stuttering of sound with pulseaudio on high loads

Asked by exactt

Binary package hint: pulseaudio

here on latest gutsy amd64

i recently switched to pulseaudio by installing pulseaudio-esd-compat . now when i play music using totem or songbird (both use gstreamer) i get little interruptions like stutterings when the computer is on high loads(high cpu and hd usage). i haven't had these problems with esd...

anyone else who can confirm this?

Hardy Alpha 1 is available at http://cdimage.ubuntu.com/releases/8.04/alpha-1/ . Please remember to install the pulseaudio-esound-compat and gstreamer0.10-pulseaudio packages, too.

thx. i already downloaded it but no time to install/test yet.

what i found out is that the pulseaudio process runs with nice level 0. if i lower it(raise priority) things get better.

You could try adding your user to the 'pulse-rt' group, then logging out and back in.

The symptom described in this bug report is alleviated by adjusting the scheduling for the pulseaudio daemon. Suggested adding the user account to the 'pulse-rt' group then logging out and back in.
