Pulse Audio works on the LTSP clients.  And I can use pavucontrol to control the volume level. I've been under the impression that I should also be able to use the Gnome volume applet.  Is this true? The applet's preferences only show ALSA and OSS mixer, and does not alter the volume for either.  Should there also be a listing for Pulse? Unfortunately, I'm not very familiar with Pulse Audio so I'm looking for tips where to start debugging. $ cat .asoundrc.asoundconf # ALSA library configuration file managed by asoundconf(1). # # MANUAL CHANGES TO THIS FILE WILL BE OVERWRITTEN! # # Manual changes to the ALSA library configuration should be implemented # by editing the ~/.asoundrc file, not by editing this file. pcm.!default { type pulse } ctl.!default { type pulse } </blockquote></div>The alsa mixer interface should work without problems. What does is the output of amixer scontrols on your terminal? Also, do you get a 'Cannot find control "Master"' while running pulseaudio? Ritesh
