If there is no entry for CD in the mixer, but for PCM,
it seems to indicate why playback from disk works, but
even (assumed) playback from CD cannot be heared.

% mixer -f /dev/mixer0
Mixer vol      is currently set to   5:5
Mixer pcm      is currently set to 100:100
Mixer line     is currently set to  75:75
Mixer mic      is currently set to   0:0
Mixer cd       is currently set to  75:75  <=== THIS ONE
Mixer rec      is currently set to  75:75
Mixer igain    is currently set to   0:0
Mixer monitor  is currently set to  75:75
Recording source: mic

This is from a HDA audio with 3 pcm devices and 3 mixer
devices.

If I remember correctly, cdrtools is the port that brings
cdrecord. There are text mode and X CD player programs
(such as XMMS with CD audio plugin, or the simple xcd)
which you could try.

It's a simple and _predictable_ tool which you can use to
make the CD drive start playing. Everything _next_ in the
signal chain (i. e. the mixer) is handled by other tools.

So if you assume that "cdcontrol -f /dev/acd0 play" makes
the CD play, then use the "mixer" command to check all the
possible audio settings to find the next thin in the signal
chain that could be wrong.
