SigmaTel High Definition Audio (Intel 945 chipset)

markchu · March 26, 2006

Audio's working for me now with 10.4.3 AppleHDA kext. Straight forward replace (ensuring permission is ok).

Tested with 2 channel speakers. Headphones work, one of the rear outs work. Haven't tried mic.

hello ,

can you tell me what step you done...

My chipset is Intel 945PM Express, audio DevID is 7661 8384...

but i try many times but still no sound ....

please help me ...

i use 10.4.3(f1111) now .....thanks

phasornc · March 28, 2006

Can someone PM me with a hint on how to get a AppleHDA.kext from 10.4.3. I have an the 10.4.4 image and I'd rather not download a whole 10.4.3 just to get one small file. I have an intel D945GTP microATX board with the sigmatel 9220. I'm getting no sound and no listing that internal audio is available under System Profiler.

Everything else is great! Oh except Chess, the built in app. Mine just freezes using the built in Intel 950 graphics.

Jezek · April 2, 2006

yahh. where do you find out the CodecID?

Edit: I found out how. I just generated a report with that everest program or whatever and then searched for codec id.

i5hawn · April 2, 2006

you know...i have this chipset/card but i don't get a device under audio...weird.

urqing · April 3, 2006

Can anyone tell me where to get AppleHDA.kext from the install DVD of Mac os x86 10.4.3?

I checked /System/Library, but there is no Extension folder. I followed all the methods described above and now I can adjust the volume, but still no sound.

sphere · April 6, 2006

Hi,

would also appreciate if someone could e-mail me the 10.4.3 version of AppleHDA.kext or a link (mail.adress@removed.com) as I don't have a 10.4.3 image and would prefer not to download it just for one tiny file.

Thanks in advance,

sphere

hi, guys, how can i find my codec id?

i tried 'everest' and generated report, but there's no codec id.

thanx

VaiOSX · April 6, 2006

I realized one thing after i installed (on XP) the sigmatel drivers provided in bootcamp.

The stac9220x5 chipset in the (intel) mac mini/MBP/iMac are not using the same schematics as the PC's built-in stac.

The drivers are really different.

So the only way to find a solution is to write a new driver, because the pins, verbsinit and widgets are built-in and assign the drivers directly. On OS X side, you'll never find anything related to in the plist.

You can compare the Proto.ini and the I5_WHQL.ini (the first one can be find in the boot camp archive and the second in the latest intel drivers for XP) you'll see how they are different.

We need now someone skilled in kext programing to write a new driver (based on the apple's one)

Zappadoc · April 6, 2006

where to find the source ? Apple didn't release the x86 main component (kernel, kext, etc.) to the Open Darwin project...so?

Zappadoc · April 7, 2006

Hi All, if you have like me a SIGMATEL STAC92XX Audio codec, I probably found the solution we need to use the Apple driver provided with the new MacIntel Mini with minor change so if someone can post it...

Thanks

Z

VaiOSX · April 7, 2006

i think it's more than just a minor change.

the apple driver is using the firmware (EFI) to get access to the built-in speaker, pins assignment is really different.

It was easier to see it in the boot camp XP drivers.

Zappadoc · April 7, 2006

VaiOSX my friend i see your terific post on (another forum ) related to XP on mac mini and it was so amazing! really great work on this sigmatel. Now we really need your help here. Thanks.

if someone get the PPC or Intel source of AppleHDA.kext let me know... couldn't find it on open darwin...

VaiOSX · April 7, 2006

thx zappa

I would like to help, but i don't own a pc computer with the sigmatel audio codec, but i can try to do something.

What i know for now is:

• The STAC codec is recognized by the kext.

• The initverbs and pin assignment are handled by the firmware (that's why you can hear the apple chime on real mac at startup).

• The LayoutIDs are used to control the STAC features, but they are not working for PC Mobos.

• The MBP and iMac (intel) are using a different Device_ID (7682) and Mac mini (7680), can be find in the AppleHDA.kext info.plist

<key>CodecID</key><integer>2206496386</integer> (in hexa = 83847682)

<key>CodecID</key><integer>2206496384</integer> (in hexa = 83847680)

If your Sub_Sys is 0x00000100, your sound card will probably be fully recognized. (it's the apple built-in audio sub system id used for all the today's intel mac).

You will get working audio by finding and replacing the NID (nodeID) values in the Info.plist of the AppleHDA.kext

you'll find more information about HDA pin's assigment here :

http://www.microsoft.com/whdc/device/audio/PinConfig.mspx

http://www.microsoft.com/whdc/device/audio/default.mspx

One thing you have to consider and check is which .ini file (while installing the sigmatel xp driver) is used on windows and check inside the pins assignment and pins ID (0x0a > line out, 0x0f line in, are the jacks pins id used for the intel mac)

these values are important to understand how your sound card is recognized and controlled.

I will check and try to give more information later.

VaiOSX · April 7, 2006

Your are right, 2206496400 is your decimal Vendor:Device ID

But did you declare your codec in the info.plist ?

Zappadoc · April 7, 2006

what do you mean? where i need to declare it?

for instance i only changed the Info.plist of the AppleHDA vers. 10.4.6. and put it (with IOAudioFamily) on extension folder. kext are loaded but with the "layout id" error...

The AppleHDAControler plugin inside have already the 27D8 ICH7 controler declare and also the ESB Audio Intel Controler (devID 269A )...

do you think that I must change the Intel controler device id for the sigmatel codec? is the sigmatel also a controler or just a codec?

you must now check with "regmon" (check in google) the pins 11, 0f, 10, 0d, 0e, 09.

When you plug a jack in your sound card jacks socket it will detect it and modify a registry key.

We need to know which jack plug is associated with which pin.

Zappadoc · April 7, 2006

don't known how to get them, I ran the Regmon and plug the headphone jack first and then unpluged it, I also plug/unpluged the line IN (it's a laptop so the main output already wired to the internal speakers...) see attachment.

Thanks.

Now if you check with in the pinconfig.doc link previously given you will know what the hexa strings mean.

(i'm also reporting a success from someone who just had to disable the front panel audio support in his bios).

The next step is to modify the info.plist in the AppleHDA.kext

But it's time to work for me... :blink:

Do i have a shot to get it working? because I have already tried many different kext's with no luck :blink:

If so what should I get/do?

Thanks

autoy · April 8, 2006

VAIOSX, could this method be also applied to ALC880 audio in order to wire the audio inputs and enabling outputs?

Zappadoc · April 8, 2006

Aerosense please read this post entirely, boot on XP get all infos as it written here (check the XP driver files) and then ask your question.

Autoy did you try the Azalia kext? seach on google you will find a solution...

check here:

http://forum.osx86project.org/index.php?showtopic=5064&st=0

ok thanks VaiOSX. I got it! (pinconfig.doc)...

Zappadoc · April 8, 2006

VaiOSX could you explain how did you get the pin number with my logs ?

Thanks.
