Re: [proaudio] pam rlimits aware setup

[Dominique Michel <dominique.michel@xxxxxxxxxxxx>]

Check at you are in the audio group:
# cat /etc/group

If not, add yourself:
# useradd -G audio username

Check the permission of the audio device:
# ls -l /dev/dsp* /dev/mixer*
lrwxrwxrwx  1 root root  9 mai 17 15:55 /dev/dsp -> sound/dsp
lrwxrwxrwx  1 root root 10 mai 17 15:55 /dev/dsp1 -> sound/dsp1
lrwxrwxrwx  1 root root 10 mai 17 15:55 /dev/dsp3 -> sound/dsp3
lrwxrwxrwx  1 root root 11 mai 17 15:55 /dev/mixer -> sound/mixer
lrwxrwxrwx  1 root root 12 mai 17 15:55 /dev/mixer1 -> sound/mixer1
lrwxrwxrwx  1 root root 12 mai 17 15:55 /dev/mixer2 -> sound/mixer2
lrwxrwxrwx  1 root root 12 mai 17 15:55 /dev/mixer3 -> sound/mixer3

If you don't have something like this:
# chgrp audio /dev/dsp* /dev/mixer*
(You may need to check udev rules if using udev, otherwise it will not work after a reboot)

Which sound card are you using?
