But recording and playback should work. If "sudo -u cau aplay -l" and aplay -l with user cau does not work, it is a bit strange. Did you re-login after adding you to a "audio" group? There should be two ways how to get permission on audio device: - Using ACL with ConsoleKit to get permission for user on the active console. Try: getfacl /dev/snd/* and find you as user which has read/write access in the ACL. - Adding user to "audio" group to get permanent access. It looks that you get both permissions. But "cannot access file /etc/alsa-pulse.conf" looks like incomplete uninstallation of pulse. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

There is /etc/profile.d/pulseaudio.sh and /etc/profile.d/pulseaudio.csh that redefine ALSA default configuration to /etc/alsa-pulse.conf. But they should be part of the pulseaudio package and should be already away.
