I've searched through my extensions folder for hours now, I do not have any other audio drivers. However, I do seem to have two Audio Devices:

 

00:14.2 Audio device [0403]: ATI Technologies Inc SBx00 Azalia (Intel HDA) [1002:4383] (The ALC1200)

01:00.1 Audio device [0403]: ATI Technologies Inc Radeon HD 3870 Audio device [1002:aa18] (The audio controller for my video card's HDMI output)

 

I am using an M3A78-T motherboard, and an ATI HD3850.

 

----------

I had the same problem. Mac OS found 2 audio devices, that is why there is no sound. Finaly I have to use the old driver ALC_1200_REALTEK_AUDIO (alcinject.kext & applehda.kext), it works but with the shutdown problem. I'm using "iPC OSx86 Universal 10.5.6" edition, I'll try to install the original edition "Mac OS X Leopard 10.5.4 9E25 Retail.dmg" and "MacOSXUpdCombo10.5.7.dmg" to see if the problem will be solved !

I'm getting the same issue as reported by firstreflex, SocratesDemise, and others - looking but still haven't found a way to disable the (not working anyway) ATI HD Audio device from detecting on the video card. For whatever reason HDMI audio detects as internal, which I presume causes a conflict making the sound settings in control panel appear to have no device at all.

 

The only other working audio driver I've found can't use all input/output for me (M3A78-EM ALC1200 - ALC_1200_REALTEK_AUDIO old packages), just stereo out and mic in on the back panel.

 

Any thoughts on where device ID's reside? I spent about an hour yesterday digging through plist and bins with editors and did not hit on anything at all. Currently have 0x174BAA30 (ATI HDA) and 0x104382FE (ALC) in profiler.

Yes man, I think you haven't the same card of mine. You can check dev-id with OSX86tools, then click on the View PCI/Vendor list button, then run lspci (or install it, if needed).

 

I would think you have a different codec dump.

Thanks marionez!

 

For "kicks and giggles" I went into device properties for both cards in windows and it comes up with (ati) dev AA01 ven 1002 and (onboard) dev 0888 ver 10EC which suggests this may be a 888 on my m3a78-em, I'll get/post the codec dump for this discussion and see if HDAPatcher can deal with it directly.

 

lspci is giving me:

00:14.2 Audio device [0403]: ATI Technologies Inc SBx00 Azalia (Intel HDA) [1002:4383]

01:00.1 Audio device [0403]: ATI Technologies Inc HD48x0 audio [1002:aa30]

which doesn't seem to conform to this hardware in any rational way.

 

edit:/ yep, its an ALC888 on my M3A78-EM, dump taken from ubuntu live attached (couldn't get knoppix to boot on this machine.) Using HDAPatcher I get nothing in profiler but more input/outputs. Using the 888 ones from the first post, all I get is HD output listed and still nothing in profiler. Using the slim pack from the first post, I get too many devices in profiler... ;) ... beats me if I know whats going on between these files, just using HDAPatcher caused my AppleHDA kext to completely disappear. In the end, I'd love it if I could figure out how to get my front panel headphone/mic leads working.

I have GA-EP43-S3L (ICH10) mobo. It says in docs that it has ALC888 built-in audio, but the best sound I get only from your ALC1200 kexts.

Anyway the sound is still too quiet and has very bad quality.

I would think that's another ALC888 known as ALC1200 case... you would attach a linux codec dump

 

can you please tell me how do i do that? from a live linux cd? with which program?

joeblowm I think you have one of many ALC 888 versions ;)

Maybe the best thing is to work on alc888 kext driver

Don't look at me on that one, the bit that I did try to do made it rather clear to me that I do not know the real relationship between all the data in a kext and it's binary. Heck, I'm still wondering that if a verb isn't a "word that indicates an action" or a brand of DVD+/-... then what is it? :) lol

Hello Marionez,

 

thanks a lot for your LAN Driver which fixed my sleep problem. But now i have another Problem. I tried to install your latest audio driver (slim version) but i didn´t found ALCinjector.kext and ALC1200fix.kext. I tried all i could, but it seemed not to be there. :)

 

Driver.tiff

 

Do you have any idea what to do? i tried to delete only the applehda.kext and the extensions.mkext but it didnt worked. So i would be soooo glad if you would have an idea for my problem. :(

 

I have an Asus P5Q Pro Board. Thanks a lot,

 

Many Greetings

Patrick

You don't need alcinj and alc1200fix because applehda comes already fixed itself and doesn't need any injector.

 

Go in your extension folder and remove alcinjector, alc1200fix, applehda, hdaenabler any azalia and alcOLDdriver.

Then download the pack (10.5.7 version if you're running that osx version) and install it!

 

He did that on your mobo: http://www.insanelymac.com/forum/index.php...t&p=1167551

Thank you Marionez, In exact that way i tried to, but to remove alcinjector, alc1200fix, applehda, hdaenabler any azalia and alcOLDdriver those drivers have to be in this folder, but as you can see on the picture, there are no such files. The Only file which exists is the applehda. I tried to delete this driver and the extensions.mkext and to install the slim driver but the problem is still there. I don´t now what to do now....

 

Do you have any idea, why those files do not exist? And what possibilities do i now have? Maybe you want to have a look on my folder via Screen Sharing?

 

Many greetings

Patrick

 

Edit: I looked for the Audiofiles in System/Library/Extensions/ and found that:

Audiofiles.tiff

 

Then i looked for HDA files and found that:

hda.tiff

 

As i looked for "ALC" i didn´t found anything. Maybe you can help me with this information, i would be very happy

Hello Marionez,

 

a few minutes ago i tried to remove vodoohda and to install the slim version. But as a result of that, no lan and audio was working so i had to reinstall vodoohda. Sorry for the many Problems and the heavy Workload to you but i dont get it,.... Maybe you have another tip for me?

 

Many greetings,

 

Patrick

I think you're on a very wrong way, voodohda has nothing to do with lan driver. If you want to use this alc1200 driver you obviously need to remove voodoohda...

I would think you have some garbage in your extension folder, because as I linked some posts ago, there's one with your mobo who used that driver. So you're doing something wrong, kext extension directory should be a place to deal with. ;)

It's strange,

 

After I install these drivers it finds my device but there are no available devices.

 

If I go back to an old alcinject method it works.

 

Anyone have any ideas what would cause this?

 

Thank you,

 

William

Hey !

 

First of all, thanks for all those things.

 

I have a problem. It's the same as SocratesDemise.

 

I dont have anything else (sound drivers) installed ! They're only your ALC1200_1056 SLIM.

 

What should I do ?

 

(and sorry for my poor english)

 

Thanks

Kristof

 

EDIT : I have a P5Q Pro.

 

EDIT2 : I think I know why ! In 10.5.5 the driver was working. Now, i'm in 10.5.7 and the driver is not working ! Why ? I don't know ...

I have a p5ql motherboard with an ICH10 chipset, and for some reason, I can see the drivers attempting to load at time of boot, but it seems to not actually provide audio. It seems to be throwing up codec errors at the time of load at boot.

marionez, the kext works great. Thank you very much. But I'm using a 5.1 sound system. Can you make a kext that support this.

 

Thanks in advance.

There's a little problem, I don't have a 5.1 sound system, so I would get mad testing a 5.1 driver :D

Anyway I'll try to solve this maybe in the second part of August.

 

In the thread you can find the whole ALC1200 verbs, already available, I think they just need a good parameters setting, and maybe there's even some other work to do on some kext files, but now I can't really work on this. :D

 

super kid, which is your mobo?

 

Would be nice having positive feedback along with mobo model, in this way, if someone is going to post in future we can see the driver works on that mobo ;)

El Gringo I checked your codec dump.

You have the same pin configuration, but subsystem ID is different and even some pin default, so even verbs.

 

P5Q

Subsystem Id: 272859902

node 25

Pin Default 44146016: [Jack] Mic at Ext Front

node 27

Pin Default 35736864: [Jack] HP Out at Ext Front

node 30

Pin Default 21262640: [Jack] SPDIF Out at Ext Rear

Hey I could use some help, I tired what you attached on this post as well as the 1st post but nothing works. I have a P6T.

      KX AUDIO DRIVER MOD
       
      Hi guys i am a small developer, i really like to use my sound blaster cards on my machines and i love also coding, so when i find the source code for the kx audio driver on git hub and then Eugene, the creator of kx audio driver decided to no longer maintain the project, i decided to start working on a mod of this driver and maintain it. 
       
      With my mod, created starting from the sources of the last official version of kx audio driver and all the small commiunity updates, i am working to keep the driver compatible with the latest mac os versions and to improove the driver over time.
       
      Supported cards are:
       
       - most of the Sound Blaster live!, live! 5.1 and live! 5.1 digital series (except for the cards not using the 10k1 architecture)
       - sound blaster pci 512 and pci 256
       - Sound Blaster Audigy, Audigy 2 and Audigy 2 zs series
       - E-MU cards based on the 10k2 sound chip (like the EMU8852 aka 0404m, including the pcie version)
       - Sound Blaster Audigy 4 (SB0610 only) and the Audigy 4 pro
       - Sound Blaster Audigy RX (SB0155)
       - other creative and e-mu cards based on the (10k1,10k2, 10k2.5 and CA10300 based cards)
       
      The NOT supported cards includes (but are not limited to):
       
       - ES1370/ES1371/ES1372/ES1373 based sound cards
       - Any CA0106 based card and cards with similar architectures (like sound blaster live! 24 bit, sound blaster audigy SE SB0570, audigy LS and similars, but audigy SA is supported)
       - Any sound blaster x-fi (some of them works on macOS using a modified version of voodoo hda)
       - Any sound blaster recon3D
       - Sound blaster Audigy FX
       - Any sound blaster Z/ZS/ZX and similar series
       - Any sound blaster AE5/AE7/AE9 series
       - Any sound card without an emu sound chip
      - Any ISA Sound card
       
      In the time being the things i have modded or added with this mod are:
       
      - cracking and stability fixes
       
      - added a more proper support for the pci express Sound Blaster audigy rx SB0155 (which basically is an audigy 4 with a pcie bridge chip) 
       
      - more user-frienly names for the cards in the settings and other system menus (so the name will be, for example, SB live! 5.1 SB0060 instead of kx SB0060 [e880] witch was shown in the original driver)
       
      - added support to sample rate changing and bit resolution change (the absolte worst supported quality is 7 khz at 8 bit dept while the absolute best is 192 khz at 32 bit depth)
       
      - inputs support
       
      - added boot args to manage the driver (more info on those soon)
       
      What i'd like to implement but i don't know how to do:
       
       - fix the support when using more than one card, to get all the cards shown in the settings and other menus,
       
       - have the gameport/midi port of older cards to be used in mac os as a midi in/out
       
      If other developers would like to join and help they are free to do so, this is a free open source project afterall, and also an hand from other people with testing and feedback will be nice.

      A New Driver for Realtek RTL8111
       
      Due to the lack of an OS X driver that makes use of the advanced features of the Realtek RTL81111/8168 series I started a new project with the aim to create a state of the art driver that gets the most out of those NICs which can be found on virtually any cheap board on the market today. Based on Realtek's Linux driver (version 8.035.0) I have written a driver that is optimized for performance while making efficient use of system resources and keeping the CPU usage down under heavy load.

      Key Features of the Driver
      Supports Realtek RTL8111/8168 B/C/D/E/F/G found on recent boards. Support for multisegment packets relieving the network stack of unnecessary copy operations when assembling packets for transmission. No-copy receive and transmit. Only small packets are copied on reception because creating a copy is more efficient than allocating a new buffer. TCP, UDP and IPv4 checksum offload (receive and transmit). TCP segmentation offload under IPv4. Support for TCP/IPv6 and UDP/IPv6 checksum offload. Fully optimized for Mountain Lion (64bit architecture) but should work with Lion too. As of now there is no support for Snow Leopard but it can be added if someone will create the necessary patches. Supports Wake on LAN. Support for Energy Efficient Ethernet (EEE) which can be disabled by setting enableEEE to NO in the drivers Info.plist without rebuild. The default is YES. The driver is published under GPLv2.  
      Limitations
      As checksum offload doesn't work with jumbo frames they are currently unsupported and will definitely never be. No support for 32bit kernels.  
      Installation
      Before you install the driver you have to remove any installed driver for RTL8111/8168.
      Goto /S/L/E and delete the old driver (Lnx2mac, AppleRealtekRTL8169, etc.). Recreate the kernel cache. Open System Preferences and delete the corresponding network interface, e. g. en0. If you forget this step you might experience strange problems with certain Apple domains, iTunes and iCloud later. Reboot. Install the new driver and recreate the kernel cache. I recommend to use Kext Wizard or a similar utility for the installation. Reboot Open System Preferences again, select Network and check if the new network interface has been created automatically or create it manually now. Configure the interface.  
      Help - I'm getting kernel panics!
      Well, before you start complaining about bugs after you upgraded macOS and ask me to publish a driver update, you should first try to resolve the issue on your own by cleaning the system caches.
      As the driver uses macOS's private network driver interface, which is supposed to be used by Apple provided drivers only, you might run into problems after an OS update because the linker may fail to recognize that IONetworking.kext has been updated and that the driver needs to be linked against the new version (Apple provided drivers avoid this problem because they are always updated together with IONetworking.kext). As a result, the linking process produces garbage and the driver may call arbitrary code when trying to call functions from IONetworking.kext. This usually results in unpredicted behavior or a kernel panic. In order to recover from such a situation, you should clean the System Caches forcing the linker to recreate it's caches:
      Delete all the files in /System/Library/Caches and it's subdirectories but leave the directories and the symbolic links intact. This is very important! Reboot. Recreate the kernel cache. Reboot again.  
      Troubleshooting
      Make sure you have followed the installation instructions especially when you have issues with certain domains while the others are working fine. Use the debug version to collect log data when trying to track down problems. The kernel log messages can be found in /var/log/system.log. For Sierra and above use "log show --predicate "processID == 0" --debug" in order to retrieve kernel logs. Include the log data when asking for support or giving feedback. I'm an engineer, not a clairvoyant. Check your BIOS settings. You might want to disable Network Boot and the UEFI Network Stack as these can interfere with the driver. Double check that you have removed any other Realtek kext from your system because they could prevent the driver from working properly. Verify your bootloader configuration, in particular the kernel flags. Avoid using npci=0x2000 or npci=0x3000.  In Terminal run netstat -s in order to display network statistics. Carefully examine the data for any unusual activity like a high number of packets with bad IP header checksums, etc. In case auto-configuration of the link layer connection doesn't work it might be necessary to select the medium manually in System Preferences under Network for the interface. Use Wireshark to create a packet dump in order to collect diagnostic information. Keep in mind that there are many manufacturers of network equipment. Although Ethernet is an IEEE standard different implementations may show different behavior causing incompatibilities. In case you are having trouble try a different switch or a different cable.  
      FAQ
      How can I retrieve the kernel logs? In Terminal type "grep kernel /var/log/system.log". I want to disable Energy Efficient Ethernet (EEE) but I don't know how? Take a look at the driver's Info.plist file. There you will find an option named <key>enableEEE</key>. Change its value from <true/> to <false/>. Don't forget to recreate the kernel cache after changing the value. WoL from S5 doesn't work with this driver but under Windows it's working. Is this a driver bug? No it isn't, the driver is working as it should because OS X doesn't support WoL from S5.  
      Current status
      The driver has been successfully tested under 10.8.x and 10.9 with the B, C, D, E, F and G versions of the RTL8111/8168 and is known to work stable on these devices.  
      Changelog
      Version 2.2.2 (2018-01-21) Force ASPM state to disabled/enabled according to the config parameter setting. Requires 10.12 or newer. Version 2.2.1 (2016-03-12): Updated underlying linux sources from Realtek to 8.041.00. Added support for RTL8111H. Implemented Apple’s polled receive driver model (RXPOLL). Requires 10.11 or newer. Support for older versions of OS X has been dropped. Version 2.0.0 (2015-06-21): Uses Apple's private driver interface introduced with 10.8. Supports packet scheduling with QFQ. Please note that 2.0.0 is identical to 2.0.0d2. Only the version number has changed. Version 1.2.3 (2014-08-23): Reworked TSO4 and added support for TSO6. Version 1.2.2 (2014-08-44): Added an option to disable Active State Power Management (ASPM, default disabled) as ASPM seems to result in unstable operation of some chipsets. Resolved a problem with Link Aggregation after reboot. Added a workaround for the multicast filter bug of chipset 17 (RTL8111F) which prevented Bonjour from working properly Version 1.2.0 (2014-04-24): Updated underlying linux sources from Realtek to 8.037.00. Improved interrupt mitigate to use a less aggressive value for 10/100 MBit connections. Version 1.1.3 (2013-11-29): Improved transmit queue handling made it possible to reduce CPU load during packet transmission. Improved deadlock detection logic in order to avoid false positives due to lost interrupts. Version 1.1.2 (2013-08-03): Improved SMB performance in certain configurations. Faster browsing of large shares. Version 1.1.0 (2013-06-08): Support for TCP/IPv6 and UDP/IPv6 checksum offload added (can be disabled in Info.plist). Maximum size of the scatter-gather-list has been increased from 24 to 40 segments to resolve performance issues with TSO4 when offloading large packets which are highly fragmented. TSO4 can be disabled in Info.plist without rebuild. Statistics gathering has been improved to deliver more detailed information (resource shortages, transmitter resets, transmitter interrupt count). The interrupt mitigate settings has been changed to improve performance with SMB and to reduce CPU load. Configuration option added to allow for user defined interrupt mitigate settings without rebuild. Version 1.0.4 (2013-05-04): Moved setLinkStatus(kIONetworkLinkValid) from start() to enable(). Cleaned up getDescCommand(). Version 1.0.3 (2013-04-25): The issue after a reboot from Windows has been eliminated. Version 1.0.2 (2013-04-22): Added support for rx checksum offload of TCP and UDP over IPv6. Version 1.0.1 (2013-03-31): Improved behavior when rx checksum offload isn't working properly. Adds the chipset's model name to IORegistry so that it will show up in System Profiler.  
      Known Issues
      There are still performance problems with regard to SMB in certain configurations. My tests indicate that Apple's Broadcom driver shows the same behavior with those configurations. Obviously it's a more general problem that is not limited to my driver. WoL does not work in certain configurations. Old systems with 3 and 4 series chipsets exhibit performance issues in recent versions of macOS because there is no optimized power management for these systems in macOS anymore as Apple dropped support for the underlying hardware a long time ago. In case you are affected, please upgrade your hardware or find an alternative solution because I have no plans for a workaround. Sorry, but I don't think that it's worth the effort.  
      Getting the driver
      The source code can be found here: https://github.com/M...driver_for_OS_X There is also a pre-build binary for Mavericks and Yosemite: https://www.insanelymac.com/forum/files/file/88-realtekrtl8111-binary/  
      Building from Source
      I'm using XCode 4.6.3 for development. You can get a free copy of XCode after becoming a member of the Apple developer program. The free membership is sufficient in order to get access to development tools and documentation.

      tl;dr: VirtualSMC causes me a flood of log messages and correlated cpu spikes. FakeSMC doesn't.
       
      Hi, I have almost finalized my Huawei Matebook X Pro Opencore setup and everything is working very well besides wifi/bt ofc (which is about to change).
       
      However, I noticed how the cpu usage sometimes went up a little and when looking at the Console I could see a never-ending flood of:

      As you can see, multiple of these per second. Another guy with the same computer is also having this issue and posted a dsdt change to fix it. This fix didn't solve anything though
      He tried to limit the Notify call by implementing a state change requirement before calling Notify.
       
      Here is the original acpi:
      Scope (_SB) { Device (LID) { Name (_HID, EisaId ("PNP0C0D") /* Lid Device */) // _HID: Hardware ID Method (_LID, 0, NotSerialized) // _LID: Lid Status { Local0 = One Local0 = ^^PCI0.LPCB.EC0.RPIN (0x05, 0x06) If ((Local0 == 0x55)) { Local0 = Zero } Else { Local0 = One } ^^PCI0.GFX0.CLID = Local0 Return (Local0) } } Device (PWRB) { Name (_HID, EisaId ("PNP0C0C") /* Power Button Device */) // _HID: Hardware ID Method (_STA, 0, NotSerialized) // _STA: Status { Return (0x0B) } } } Scope (_SB.PCI0.LPCB.EC0) { Method (_Q81, 0, NotSerialized) // _Qxx: EC Query, xx=0x00-0xFF { Local0 = ^^^^LID._LID () If ((Local0 == Zero)) { ADBG ("LID-OFF") SGOV (0x02030009, Zero) SGOV (0x02060000, Zero) } Else { ADBG ("LID-ON") SGOV (0x02030009, One) SGOV (0x02060000, One) Notify (ALSD, 0x80) // Status Change } Notify (LID, 0x80) // Status Change } } Which he changed to: 
      Scope (_SB) { Device (LID) { Name (_OLD, One) // assuming everything else.. the lid should start open? Name (_HID, EisaId ("PNP0C0D") /* Lid Device */) // _HID: Hardware ID Method (_LID, 0, NotSerialized) // _LID: Lid Status { Local0 = One Local0 = ^^PCI0.LPCB.EC0.RPIN (0x05, 0x06) If ((Local0 == 0x55)) { Local0 = Zero } Else { Local0 = One } Return (Local0) } } Device (PNLF) { Name (_HID, EisaId ("APP0002")) // _HID: Hardware ID Name (_CID, "backlight") // _CID: Compatible ID Name (_UID, 0x0A) // _UID: Unique ID Name (_STA, 0x0B) // _STA: Status } Device (PWRB) { Name (_HID, EisaId ("PNP0C0C") /* Power Button Device */) // _HID: Hardware ID Method (_STA, 0, NotSerialized) // _STA: Status { Return (0x0B) } } } Scope (_SB.PCI0.LPCB.EC0) { Method (_Q81, 0, NotSerialized) // _Qxx: EC Query, xx=0x00-0xFF { Local0 = ^^^^LID._LID () If ((Local0 == Zero)) { ADBG ("LID-OFF") SGOV (0x02030009, Zero) SGOV (0x02060000, Zero) } Else { ADBG ("LID-ON") SGOV (0x02030009, One) SGOV (0x02060000, One) Notify (ALSD, 0x80) // Status Change } If ((^^^^LID._OLD != Local0)) { Notify (LID, 0x80) // Status Change ^^^^LID._OLD = Local0 } } } Besides me not seeing any reason to declare _OLD in LID. The idea itself shouldn't be too bad right? Well, as I said, his fix didn't work.
       
      In fact, to prove that Method _Q81 doesn't have anything to do with the issue at all, I created a Clover/Opencore patch to change _Q81 to XQ81. This resulted in my lid not working at all of course, but the log flooding still persisted!
      So _Q81 doesn't have anything to do with the issue afaik.
       
      Now, further Google searches led me to a chinese post where he tied the issue to VirtualSMC. And indeed, by migrating to FakeSMC the issue is no more.
       
      Unfortunately, I'm very fond of VirtualSMC for various reasons. So I would very much like to keep it. If not I'd have to implement the old way of doing Battery monitoring etcetc. Which isn't very elegant and update proof as it requires DSDT patching.
       
      So, I do believe that the issue may very well be in the DSDT code, perhaps in the ambient light part. I'm not very skilled at this and just started studying the ACPI spec 3 days ago.
       
      Could someone please help me out? Thanks a lot in advance
