Public bug reported: Binary package hint: pulseaudio
Pulseaudio has irregularly a high cpu usage on older thin clients used as LTSP clients which causes interruptions of sound (approx 2 sec or more). LTSP connects pa to localhost and uses an ssh socket for connection to the server. With 0.9.14 I experienced similar problems like https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/236936. Thus I installed: r...@s400-13:/# dpkg -l | grep pulse ii gstreamer0.10-pulseaudio 0.10.14-1 GStreamer plugin for PulseAudio ii libpulse-browse0 1:0.9.15-4ubuntu1 PulseAudio client libraries (zeroconf suppor ii libpulse0 1:0.9.15-4ubuntu1 PulseAudio client libraries ii pulseaudio 1:0.9.15-4ubuntu1 PulseAudio sound server ii pulseaudio-esound-compat 1:0.9.15-4ubuntu1 PulseAudio ESD compatibility layer ii pulseaudio-module-hal 1:0.9.15-4ubuntu1 HAL device detection module for PulseAudio s ii pulseaudio-module-x11 1:0.9.15-4ubuntu1 X11 module for PulseAudio sound server ii pulseaudio-utils 1:0.9.15-4ubuntu1 Command line tools for the PulseAudio sound Please also see the syslog file attached.
