Actually, the G4 "Quicksilver" PowerMac3,5 is propably more alike to the G4 "Digital Audio" PowerMac3,4 in this regard. The device ID on the Digital Audio is decimal 14. The Quicksilver is decimal 21. PowerMac3,4 Digital Audio: Device ID 14, ??? chip PowerMac3,5 Quicksilver: Device ID 21, TAS 3001C CODEC chip PowerMac3,6 Mirrored Drive Doors: Device ID 22, TAS3004 CODEC chip $LINUX/sound/aoa/codecs/tas.c driver was originally made for the TAS3004, which I figure because only "tas 3004" is mentioned in the source, no other. Since the Quicksilver, which is newer than the Digital Audio, doesn't have the TAS3004 chip (Mac OS X System Profiler states "Texas Intruments TAS3001C"), but the Digital Audio seemed to work fine with the aoa-tas codec too (it's already in the kernel) I tried it with the Quicksilver as well. The modules loads without errors, the sound card is listed (/proc/asound/cards) and the volume controls are usable. I played some sound and everything seemed to work fine. So I submitted the patch. So now I have to appologize. And I'm glad the patch hasn't been accepted. Why? Because I had booted with the wrong kernel when I tested if the sound played okay. I must have still used the powermac sound module, not aoa. BIG APPOLOGIES. I tested again yesterday and today and can't get it to play a sound. I also checked the logs and all the ALSA stuff (in /proc/asound). Everything seems okay. I then tried a different mixer: pavucontrol -- because I have trouble to unmute without this on my PC too. Now the surprise: it won't let me unmute. Maybe it's just my system. I use Gentoo Linux and just recently updated the whole system to use Pulse Audio. If anyone else could try the patch or write a new one on their G4 Quicksilvers I'd be happy. And: I do understand the sign-off limiting to real names. It's a good thing.
