Re: Sound problems - CD Player not working

[James Henstridge <james daa com au>]

Playing CDs is a bit different from playing sound files.  If you have ever
opened up your case, you will see there is a cable running from the back
of your cd drive to your soundcard.  To play audio CDs, the CD player app
simply tells the drive to start sending the audio signal to the sound
card, bypassing /dev/dsp.

OK, that is why /dev/dsp is not being used.  Now how to fix the problem.
First find out what the device name for you CD drive is.  The easiest way
to do this is to look in the /etc/fstab file, and see if there is an entry
for your cd drive (it will probably list the mount point as /mnt/cdrom or
/cdrom and use an iso9660 file system).

It is probably a good idea to make a link from /dev/cdrom to this device
if there isn't one.  If /dev/hdc is your cd drive, type the following:
  ln -sf hdc /dev/cdrom

You will also want to make sure that you can write to this device:
  chmod a+w /dev/cdrom
(this is quite safe, since the cdrom drive takes read only media).

Now everything should be working properly.

James.
