Is it possible that you can figure out how to add software volume and balance control to my AC97 sound processor?

00:11.5 Multimedia audio controller [0401]: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller [1106:3059] (rev 60)

I patched these two for my P5K-VM. They are based on the legacyHDA by stickpin but his doesnt work on 10.5.7 or 10.6

 ALC883_10.5.7_LegacyHDA.zip ( 14.08K ) Number of downloads: 31

 ALC883_SnowLeopard.zip ( 46.69K ) Number of downloads: 93


Edit: 10.5.8 changed the HDA kext again. It has a similar layout as the 10.6 (for now), so you can use the kexts I modded for SL to get the audio working on 10.5.8...

No, AC97 is another driver, another story.
