Summary:                    compiles, but no sound comes out
Description: 
This is a plain vanilla kernel 2.6.6, which uses ALSA 1.0.4.

The kernel compiles fine, the snd_powermac module loads without any error,
but no sound comes up.

Running alsamixer gives me a mixer screen where none of the sliders can be
moved.

Power management on the driver is also broken (well, doesn't exist at all)
and after hibernation the module has to be reloaded to get sound at all.

Note that this is with a chipset where I actually *do* get sound (the one
in a PowerBook5,6), not a chipset where sound doesn't work at all.

Kernel 2.6.13 shows some major improvements: 
Almost everything ALSA works on Burgundy as it should! :-) 
Whoever worked on this since 2.6.11 deserves a big hug!

master volume:    works as expected.
headphone volume: seems to control the internal stereo speakers instead.
Oops!
headphone detect: (what is this supposed to do?)
analog CD volume: works as expected.
line input:       (no analog signal to feed the input jack and test it)
microphone input: (feedbacks if I rise it high enough, so I'd assume it
works)
mono PC speaker:  seems to control the stereo headphones instead. Oops!
auto-mute:        (what is this supposed to do?)
console beep:     works as expected.

On a general note, I cannot seem to completely silence the internal stereo
speakers or the headphones, other than by muting the master volume.

Still, this is already a *major* improvement over previous ALSA releases:
I finally get some sound on this iMac CRT's Burgundy chip! Many thanks!
:-)
