Public bug reported: Binary package hint: pulseaudio
When I have pulseaudio (ver. 0.9.10-2ubuntu9.3 from intrepid-updates) installed, my sound card disappears from the Volume Applet. In that case, the only device option available in Volume Applet is my USB microphone. There is no way to control loudspeaker volume. However, if I uninstall pulseaudio (which forces ubuntu-desktop also to be uninstalled), my sound card reappears. This problem appeared for no apparent reason. It may have related to update of kernel from ver. 2-6-27.11-26 to 2-6-27.11-27, but I didn't notice it until a couple of weeks after the update so I don't know whether there's any relationship. When pulseaudio is installed, alsamixer will not run. (When pulseaudio is uninstalled, alsamixer works properly). This is the output when I try to run alsamixer with pulseaudio installed: ALSA lib conf.c:2700:(snd_config_hooks_call) Cannot open shared library libasound_module_conf_pulse.so ALSA lib control.c:909:(snd_ctl_open_noupdate) Invalid CTL default alsamixer: function snd_ctl_open failed for default: No such file or directory This may be a related bug: https://bugs.launchpad.net/bugs/273578. However, my problem is not solved by killing pulseaudio because it isn't running in the first place. When I start pulseaudio from a terminal, the output is: W: ltdl-bind-now.c: Failed to find original dlopen loader.

Ttrying to produce sound with pulseaudio running causes applications to crash. Downgrading pulseaudio to ver. 0.9.10-2ubuntu9 doesn't make a difference. My soundcard: Via Technologies, Inc.
