1. Read "Writing Audio Drivers" on apple's site.
2. Get specs on your card, especially device registers.
3. track down BSD or Linux(ALSA) drivers for your card.
4. Port it.
5. dogbert's CMI driver found on 3rd party drivers section in wiki is helpful for ac97 pci cards.

That's all i can do for you.

Im pretty sure i deleted old kext

kext v1 info:.....
kext v2 info...
initHardware code is not the same between 2 logs
Also I restarted between the 2 versions

initHardware address is virtual, therefore different every time. Where did you try V3???

Ok cool. Verbtables are the same for the Dell Inspiron 6400 and 9400. Any other laptop/desktop people out there with sigmatel 9200 or 9220s?

[james2mart]

Ok well now that my code got deleted, I've since restarted, but using the Linux ALSA code as reference instead. This code makes alot more sense. Come to find out, the BSD driver did not work with the ICH7 chip anyway, but the Linux one does. So far in my COMPLETE rewrite, I've managed to CORRECTLY allocate memory for the Buffer Descriptor Lists, Position Buffer, and Stream Buffer(s). I have also allocated DMA memory for the CORB/RIRB buffers. These are ring buffers used for sending commands to the codec without using immediate response (IR) implementation. IR is only to be used when DMA is not readily availiable. So far, the stream buffer, position buffer, and BDLs are not actually running, but the RIRB/CORB ring buffers are running and successfully sending and receiving commands from the codec. This is a HUGE step in the right direction, and you all should see some results soon.

Excuse my ignorance, but are you saying that you can get much better sound quality from this card once a driver has been developed? Right now the quality ain't that bad, but if a driver will improve it, you have my support. Thanks a lot for your hard work!

[drib]

No, at this moment, there is no working driver for the Sigmatel 9200 for OSX86. Do not confuse it with the Sigmatel 9220 etc

So, this is not for the soundcard on the Intel GNTLKR?

[dmk]

I assume this is the sound type used in the widely-loved Dell E1505 laptops, etc?

And if that is the case, I must say...THANK YOU SO MUCH for your efforts in attempting to write this.  People like me who can't code worth a darn truly do appreciate your efforts and work, and I'm 110% behind you -- Look forward to seeing results, but understand it takes time, trial and error.  Best of luck and again thank you!

Well, I guess right now it is only for the Sigmatel 9200 (E1505, 1705/9400 ...). It might be used on the other Sigmatels (92X0, the Intel GNTLKR uses the 9220), but I thought their architecture is quiet different from the Sigmatel 9200.
Anyway, I think the best man for this answer is james2mart himself...

[james2mart]

All HDA Codecs function in the same way. It is very feasible to write a driver that reads all of the required information from the codec. Unfortunately, it is EXTREMELY difficult. Take a look at the ALSA hda implementation for universal coding. It's about 10 files and close to 10000 lines of code. If you hardcode in the node IDs and types, then you dont have need for all the recursive functions that ALSA uses to determine codec capabilities.

As of now, the hardcoded node IDs are for the Sigmatel 9200, and 9200D, and SOME 9220s that have the device ID of 0x83847690. Basically this driver will MATCH with any HDA codec ON AN ICH7 BUS. It will only work with device IDs 7691 and 7690. If I get it to work.

How do I know what my device ID # is? (For the soundcard on the Intel GNTLKR)

[Neonkoala]

In windows go to Start > Run and in the dialog box type "dxdiag" without the quotes. Click on the sound tab and look at Device ID and you can extract the numbers from that.

[sccarlso]

All I can say is if you can get the sound working on my Dell E1505 you will be a god to many many people.    It's the only thing that doesn't work on my E1505, everything else works almost out of the box, including QE video, max resolution on the wide screen, wireless (dell card, not intel pro), bluetooth (dell card) and it's FAST!  Even though it's a solo 1.6Ghz, it's still faster at most simple tasks than my dual core 3Gig XP machine.

Good luck!

Yeah, and even sleep works. I just have a little annoyance (besides using only one core and not having sound or wireless) and is that the key right of the left shift button (the "<" & ">" one) just doesn't work =(
