Yes, that explains what happens on my notebook and corresponds to
what the Handbook says:
If all goes well, you should now have a functioning sound card. If your
CD-ROM or DVD-ROM drive's audio-out pins are properly connected to your
sound card, you can put a CD in the drive and play it with
cdcontrol(1):
% cdcontrol -f /dev/acd0 play 1
Indeed, both the 'mixer' command and the (much more comfortable) 'rexima'
port show only 5 mixer devices:
Mixer vol is currently set to 12:12
Mixer pcm is currently set to 30:30
Mixer speaker is currently set to 8:8
Mixer mic is currently set to 0:0
Mixer rec is currently set to 0:0
There is no 'cd' mixer device, and the only mixer device file on
this notebook is '/dev/mixer0'.
But this does not explain why mplayer, in contrast with vlc, refuses
to play the CD, does it ?
What is the meaning and reason of the above FAILURE lines ?
2 identical lines with the GENERIC kernel,
1 single line, if I add 'device atapicam'.
That is apparently the only difference between the two cases.
Thank you again and in advance for any further help.
