Title:
Heavy stutter without system load
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
Binary package hint: pulseaudio
Description: Ubuntu lucid (development branch)
Release: 10.04 AMD64
With turn from karmic to lucid beta the sound is poping and stuttering while
playing trough pulseaudio. When this happens i got tons of these lines in
messages.
Apr 19 12:13:29 agamemnon pulseaudio[5718]: ratelimit.c: 5 events suppressed
Apr 19 12:18:05 agamemnon pulseaudio[5718]: ratelimit.c: 1 events suppressed
Sometimes pulse goes to sleep_state and the sound stops completely, audio
applications grey out in this case.
The chip is a rt888 HDA. I tryed to set higher priority at
/etc/pulse/daemon.conf but -11 and forbidden realtime scheduling seems
to be the reality. I tryed different resample-method without an
effect. In karmic pulse runs with -20 and everything was fine.
pulseaudio:
Installed: 1:0.9.22~0.9.21+stable-queue-32-g8478-0ubuntu14
There is 2x 2.8GHz CPU power, 4gig of 1333 mem but load isn't needed
to let pulse stutter und popple. Other distros enable pulse-rt to
workaround this, ubuntu did not not have this group.
