Title:
0.9.15: irregular excessive cpu usage
Status in pulseaudio package in Ubuntu:
Expired
Bug description:
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:
root@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

ii pulseaudio 1:0.9.15-4ubuntu1

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. You can see all the options
PA is started with here:
pulse 3118 4.9 1.2 95660 5872 ? S<l 20:32 1:27
/usr/bin/pulseaudio --system -vvvv --exit-idle-time=-1 --disable-shm

anonymous=1 -L module-native-protocol-tcp auth-anonymous=1 -L module-
volume-restore -L module-rescue-streams -L module-native-protocol-unix
auth-anonymous=1 -n
This only happens on older clients, new clients work smooth.I also
tried the hint to comment out "tsched=0" seen
here:https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/330006.
No result.
