[HOW TO]alc 662 Asrock for device HDAC@7

2 posts in this topic

Recommended Posts

after some troubles I've get a way to fix ''native'' audio support on my asrock alivenf7g.

It doesn't support voodoohda and snow apple hda so I've try to install applehda from 10.5.7 patched with taruga's hdaPatcher, a custom dummy kext containing pinconfig and device-id injetion and device HDEF under ''Name (_ADR, 0x00070000)'' in my dsdt.

Device (HDEF)
           {
               Name (_ADR, 0x00070000)
               Method (_DSM, 4, NotSerialized)
               {
                   Store (Package (0x08)
                       {
                           "layout-id", 
                           Buffer (0x04)
                           {
                               0x0C, 0x00, 0x00, 0x00
                           }, 
                           "codec-id", 
                           Buffer (0x04)
                           {
                               0x62, 0x06, 0xEC, 0x10
                           }, 
                           "device-type", 
                           Buffer (0x0F)
                           {
                               "Realtek ALC662"
                           }, 
                           "PinConfigurations", 
                           Buffer (Zero) {}
                       }, Local0)
                   DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                   Return (Local0)
               }
           }

 

et voilà, audio works 2in & 2out. perfect!

the strange thing is that the audio bridge 00070000 is different from standard 001B0000 so I believe that snow hda won't recognize driver

Another way to get only output working is using leopard applehda (above) and appleazaliaAudio.kext AppleAzaliaAudio.kext.zip no dsdt patch needed

    • ok, I am having a weird glitch with my Primary bios after modding it myself. can I get some help getting a Clean osmosis modded (for High Sierra and beyond) Bios Image?   https://www.gigabyte.com/us/Motherboard/GA-Z87X-UD5-TH-rev-1x#support-dl   the version I have always stuck with was F4, because the F5d.  I use a custom iMac 14,2 configuration that has been stable, the issues I have with stability come from not being able to get Access to the Bios, and prior to my attempt to mod it has been stable with up to High Sierra using clover, and up to Sierra with my very very old Ozmosis 894m F4 rom. I am not opposed to installing Ozmosis on the EFI Partition, But Gigabyte locked the Bios loading .efi Files, there is no shell to Force it to load HFS+ or APFS drivers.   so what I am asking for is assistance ether unlocking a Shell for my Bios, or getting a bios with the APFS, HFS+, and Ozmosis related files in it.   thanks again for everyones assistance.

    •     Install from fresh again. This time without Tony Tools, follow some guide in this topic. Install IntelHD kexts as usual in S/L/E and thats it. Everything works again, except for backlight, I never could have this work, also got heating problem and when boots apple logo dissapears from like 5 seconds and then appear the login window... Any ideas on any of this????

    • somehow I can't post a topic using safari and Firefox on Mac. no box for inserting text, is this kind of maintenance?  
    • Hello Allan!   I do have ACPIBatteryManager.kext and if i use IntelBacklight then I get stuck on boot with an error along of the lines of "busy timeout, (60s), : 'PEG0'". I have tried to patch the DSDT but failed. If i understand right, ACPIBatteryManager.kext needs DSDT edits to work? same goes for IntelBacklight?   EDIT: I tried to edit my stock DSDT using MacIASL again and i applied the battery patch for Asus Q550LF from @RehabMan Repo! I also applied the AsusFNkey DSDT patch. Now the battery meter pops up when i unplug the laptop. If i plug the charger back in, then the battery meter stays but does not update to show that the charger has been plugged in. Ive attached the DSDT below.. DSDT.aml.zip
