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.

to be sure: the mixer value cannot be changed via amixer program?

----------------------------------------------------------------------

Yes, that fails too.  For example:

root@omena:/home/q-funk# amixer set CD 80%
Simple mixer control 'CD',0
  Capabilities: pvolume
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 100
  Front Left: Playback 80 [80%]
  Front Right: Playback 80 [80%]
root@omena:/home/q-funk# amixer get CD
Simple mixer control 'CD',0
  Capabilities: pvolume
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 100
  Front Left: Playback 0 [0%]
  Front Right: Playback 0 [0%]
root@omena:/home/q-funk#

That has always failed on this hardware using ALSA.  

However, the old OSS driver dmasound_pmac produces sounds, so I know that
the hardware is not at fault. Then again, since OSS is being deprecated, I
cannot afford to continue using it for too long.

I would just like to point out that this is still broken in kernel 2.6.7.

Still broken in kernel 2.6.8.1 also.
