No Sound when using CDPlayer in Linux

[A_KeeleLeveller]

I can get audio CDs to play under Window$, and when I run KsCD in a terminal as root, but when I run it from either the K menu or in a terminal using my normal account, nothing, even though the display shows the CD playing. XMMS shows the CD playing, but still no sound.

Any ideas?

have you checked to see if the cable is connected between your CD and Sound Card? Windows does not require the cable but Linux does.

I tried to send you the following private message but it seems that you have private messages from moderators disabled:

I split your post out of carljenkins' thread on no sound into its own in the software forum.

Per our posting guidelines, in the future, please do not post new questions/problems at the end of other people's threads. You will get your question answered much faster if you start a new thread, and it makes it far less confusung for others to read.

Thank you.

Check your mixer settings

Ensure that the "CD" volume is up and not muted.

What distro are you using??

If it is Mandrake, check AUMIX and turn the volumes up, default is all down.

If the sound works as root, but not as a user, that's not the cable between the CDR and the sound card, it's a basic permissions problem is all that it is.

The command ls -l /dev/dsp* will give you what the permissions/groups and such of the main (most common) sound device.

If the permissions are root root, then you may want to use chgrp as root to change the group to audio, and then put yourself into the audio group. It will require that you log out and log back in to update your joining the new group.

You will also want to set the groups permissions on that device to *checks* read/write.

Heres the output from mine.
11:32PM % ll /dev/dsp* ~ <knute>
lrwxrwxrwx 1 root root 9 Nov 3 08:49 /dev/dsp -> /dev/dsp0
crw-rw---- 1 root audio 14, 3 Nov 3 08:48 /dev/dsp0
crw-rw---- 1 root audio 14, 19 Nov 3 08:48 /dev/dsp1
crw-rw---- 1 root audio 14, 35 Nov 3 08:48 /dev/dsp2
crw-rw---- 1 root audio 14, 51 Nov 3 08:48 /dev/dsp3
11:32PM % ~ <knute>

dsp is a symlink referring to dsp0, which is set up so that users in the audio group have the access to it.

Thanks, that last suggestion sorted it out.

im having similar problems. with xmms, i can play mp3 as root, but as a regular user

here is what i get with i type ls -l /dev/dsp*

crwxrwxr-- 1 root audio 14, 3 Sep 15 2003 /dev/dsp
crw-rw---- 1 root root 14, 19 Sep 15 2003 /dev/dsp1
crw-rw---- 1 root root 55, 0 Sep 15 2003 /dev/dsp56k


However, i can play CD's just fine via my regular logged in account
