ALSA support on PowerMac
This page attempts to summarize the status of support for ALSA sound on Mac ["PowerPC"] hardware. The info was gathered from this [http://lists.debian.org/debian-powerpc/2005/03/msg00883.html thread on debian-powerpc] and mimics the controls offered by alsamixer.
Please add any missing info you can provide.
Note that there is an [http://tinyurl.com/b44ls Ubuntu bounty] of 500 USD for whoever manages to fix ALSA support for all PowerMac subarchitectures.
More info on the [https://bugtrack.alsa-project.org/alsa-bug/view.php?id=306 ALSA bug tracker] (use the Guest login to view).

NOTES
AWACS (601, 603, 604, 604e a.k.a. Old World)
- Beeping goes to both the internal speaker and the audio output, because the circuitry to mute the internal speaker is not detected by the driver. As such, getting beeps exclusively to the audio output requires disconnecting the cable going to the internal speaker.
Screamer (beige G3)
- CD playback requires selecting the CD source as recordable.
- Output jack doubles as speaker/headphones.
- Input jack doubles as line/microphone.
Burgundy (iMac G3)
As of kernel 2.6.13 (ALSA 1.0.9a):
- Most of the mutes don't work, or their state cannot be saved.
- Headphone detection induced auto-muting of the speakers doesn't work.
- Controls for the stereo speakers and for the headphones are reversed (wrong offset in the control matrix?).
Snapper
G5 desktop
As of kernel 2.6.12 (ALSA 1.0.9):
- The 3 outputs (line/headphones/speakers) work correctly, along with auto-detection of an insterted plug on the first two output.
- The digital input is not working yet.
PowerBook iow. alu post-february-2005 (PowerBook 5,6)
- Analog CD control is not available.
