Sound problem

moyix · August 18, 2005

I've got a slightly odd sound issue--the kernel extension shows up as loaded fine:

...
  50    2 0xd70a4000 0x16000    0x15000    com.apple.iokit.IOAudioFamily (1.5.5b2) <31 11>
  51    1 0xd6ffa000 0xd000     0xc000     com.apple.driver.AppleAC97Audio (1.0.0) <50 11>
  52    0 0xd7007000 0x4000     0x3000     com.apple.driver.AppleAC97AudioIntelICH (1.0.0) <51 16 11>
...

And, indeed, if I look at /System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/AppleAC97AudioIntelICH.kext/Contents/Info.plist, I find that my vendor/product ID are already in there under the ICH5 AC97 Audio section, so no modification should be required.

Furthermore, I can see and set the volume on both the menubar and in the System Preferences. In the Sound panel's Output tab, it lists Line Out and SPDIF Out with the ports "AC97 Audio (PCM)" and "AC97 Audio (SPDIF)" respectively.

And yet, despite all these encouraging signs, there's no sound from anything. iTunes (yay SSE2 kernel patch) will appear to play, and the visualizations even work, but no sound is produced from anything, nor do I hear any confirmation beeps when I change the sound volume.

To deal with the obvious: yes, I checked all cabling, and tried different ports on the sound card, and adjusted the system and speaker volume. The speakers work with another system.

The Vendor/Product IDs are 8086 and 24d5 (identified by Linux as "82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller").

Anyone have any ideas? A secret volume control in OSX that I haven't found? Anything?

moyix · August 18, 2005

HAHAHA! For some reason it's routing audio out the front jack, which I forgot I even had connected. Sound is working!

cecrux · August 18, 2005

8086 and 24d5 isnt that a soundmax onboard card?

I have the same problem here, volume icon is showing up,visulazation on itunes etc but no sound.

I got the right outlet...so that one is checked.

How does your Info plist look like? my vendor and product ID didnt show under the ICH5.

I've modified it by adding the ID , but with no luck im going around in circles here.

any clues? thanks

moyix · August 18, 2005

With mine (dd'd deadmoo image) the id was already in there. the Info.plist looks like (abbreviated):

                <key>ICH5 AC97 Audio</key>
               <dict>
                       <key>CFBundleIdentifier</key>
                       <string>com.apple.driver.AppleAC97AudioIntelICH</string>
                       <key>ICH Type</key>
                       <integer>5</integer>
                       <key>IOClass</key>
                       <string>AppleAC97AudioIntelICH</string>
                       <key>IOPCIPrimaryMatch</key>
                       <string>0x24d58086</string>
                       <key>IOProbeScore</key>
                       <integer>10000</integer>
                       <key>IOProviderClass</key>
                       <string>IOPCIDevice</string>
               </dict>

and as you can see it's right there... I'm not sure what the actual brand name of the sound chip is, but it identifies itself as Intel (the vendor code, 8086, refers to one of Intel's first chips--cute, eh?)

Does the AC'97 driver load at all (as shown with kextstats)?

cecrux · August 18, 2005

Thanks for the help moyix.

...as a long time windows user i knew i was trouble once i decided to dig into this one.

-----------------------------

Doesent look right...I used deadmoos image too,but i unpatched it (with his patch) to enable rosetta because i have SS3.So something must have happened there...

I can only see AC97 Audio (PCM) the AC97 Audio (SPDIF) isnt loaded at all.

This is probably pretty simple...but im not seeing it.

wlr3 · August 18, 2005

I have the same VEN and DEV and mine appears that it should work as well, however no output.

If I play a CD, I can see and adjust the input level as "Stereo Mix", not "CD". Extensions are loaded and all appears normal, just no sound output.

I have also edited the Info.plist for my hardware and have installed the SSE3->SSE2 and CG LibSys.

Edit: Maybe the system is trying to route output to a non-existant port (I don't have a front port)? Is there a way to verify or change the output port?

inv · August 18, 2005

Hello,

Same problem here... Everything configured, turned on, connected and so on, but no sound at all..

wlr3: I also think that's the problem, but how can we solve it?

anyone has any idea?

regards,

i

EDIT: I don't have a front sound jack..

.zero · August 18, 2005

same problem here....no front jack...no fun :rolleyes: anyone??

inv · August 19, 2005

damn.. no help at all?

jchowland · August 20, 2005

If you've got an inbuilt sound card, but is covered up or not being used - test all the ports - i've got mine working on the centre speaker for 5.1!

leoniloilo · August 20, 2005

My mobo = Asus P4C800 Deluxe.

built in audio = AI Audio = ADI AD1985 6-channel audio codec.

Pentium4@3 = no SSE3.

System is dual booting:

either WinXP or OSX10.4.1.

For WinXP i was using an Creative Audigy2,

but this isn't working under OSX.

i removed the Audigy2,

and enabled onboard audio in bios.

My Mac comes from Deadmoo.

I applied all Maxxus patches.

Audio is working perfectly.

Both channels.

Cable attached to audio out, "the green one".

OK - I've got this problem too (and no front audio port!). The mic input is working fine - I can see the level meter bouncing on the audio system preferences input panel when I bang on the mic. It's gotta be simple once you know the answer.

As stupid as it is .. check if mute is checked

that got me once heh.

inv · August 23, 2005

GOT IT!

just go to the Audio Midi Setup... BUT... being root!

i used:

sudo -s
cd Applications/Utilities/Audio MIDI Setup.app/Contents/MacOS
./Audio\ MIDI\ Setup

Then.. In "Audio Devices" i found my Ac97 already configured..

I've selected the output one in "properties for" and choose format = 4ch-16bit

then, I've selected "configure speakers"

and I've replaced 1 and 2 with 3 and 4..

aply, done, close, DONE!

works for me

i

EDIT: Could also be the solution for other problems in other cards... check it out...

August 23, 2005

Ok your rule! i got my sound to work too!

Thanks your just made my day

golden86 · August 24, 2005

hey, i followed http://wiki.osx86project.org/wiki/index.php/Audio

and i got the same device ID 0x24d58086, after i done the stuff from the guide

my mac wont boot up anymore, it stalls at the grey apple boot up screen doesnt go anyway, and tried -x wont help,

could i possibly make a mistake in the plist file and did something wrong, how do i restore the original file

and what does chown -R root:wheel /System/Library/Extensions and kextload AppleAC97AudioIntelICH.kext do?

TonyDennis · August 24, 2005

I am having the same problem on my Gateway 4530GZ (Intel Pentium M, no SSE3, deadmoo's image, ICH4 (24c58086, the default). What's weird is sometimes I get sound for a brief moment. Every now and then when I change the volume it will make the bleep noise, and once I got the BRRRR error sound when I hit backspace too many times in Terminal. I cannot figure out why sound is intermittent (or very rare, anyway). iTunes says it's playing, I can control the volume, I can see the visualizations, I can see the input meter go up and down... quite mysterious.

I've attached my CoreAudio data from the Audio MIDI Setup.

Any help would be greatly appreciated.

THANKYOU. I was tearing my hair out before. This worked perfectly. THANKYOU.

My only tip to someone else would be to try renaming "Audio MIDI Setup" to "AudioMIDISetup" to get rid of the spaces just incase you get the Error about the location not existing. (you can change it back when you get your sound working)

After that just change the second command to cd /Applications/Utilites/AudioMIDISetup.app/Contents/MacOS

wlr3 · August 24, 2005

Great Job, Inv! Worked perfectly for me, thanks much!

Blackice · August 24, 2005

Hi!

I have the same audio card, but the problem is that the kernel extension refuses to load. Something about a missing IOUSBFamily and IOUSBUserClient...

anyone able to supply these?

You are a God. Bless you.

Now if I could figure out how to get this Mad Dog Card working so I can have optical audio out

johnnybluejeans · August 24, 2005

This seems like it could be the problem for my card, but I can only select stereo output.

My card is a Conexant, AC97 compliant card.

Its vendor and device ID is the one listed under ICH6 by default: 0x266e8086.

Some strange behavior I have:

- I can record sounds just fine. I tested this by recording a sound and then testing it on my Windows machine..

- I get absolutely no sound output. But my speaker does "pop" every once in a while

- No sound output through the Mic jack like some folks have noticed.

Also, under System Profiler in the Extensions category I have this error in AppleAC97AudioIntelICH:

Dependencies: Incomplete

Dependency Errors: com.apple.driver.AppleAC97Audio: No valid version of this dependency can be found

inv · August 24, 2005

have you tried to configure it through Audio Midi Setup as I did? being root and all..

hope it helps*

inv

johnnybluejeans · August 24, 2005

Yeah, tried it as root. No difference. : /

I also have SPDIF Out listed as an output device. But it is the same story there...

TheMessiahNL · August 24, 2005

I can't get it to work also.

I have a Acer Aspire 1661 Laptop. Its also uses Realteck AC97 Audio.

0x41431002 or 43411002 i'm not sure. But 1 of them.

Hopefully someone can fix it. Futher the system runs nice. Everything works.
