Bug Description

On resume from ram/disk, pulseaudio tool, pacmd eats 100 of cpu time.
This can be reproduced by running:

cd /usr/lib/pm-utils/sleep.d/
export PM_FUNCTIONS=$(pwd)/functions

sudo -E /usr/lib/pm-utils/sleep.d/01PulseAudio hibernate

The 01PulseAudio looks suspicios:

get_pulse_users() {
    ps -C pulseaudio -o uid= | tr -d ' '

get_pulse_sinks() {
    echo list-sinks | pacmd | awk '/\* index:/ {print $3}'

get_pulse_sources() {
    echo list-sources | pacmd | awk '/\* index:/ {print $3}'


These functions are supposed to be run as root, right?
But then pacmd couldn't connect to pulseaudio, isn't it?

I admit that I installed pulseaudio from source (latest git) on top of ubuntu's one
I have ubuntu 9.10

Please purge pulseaudio and reinstall it, then reproduce it.

I've uploaded some test packages to the ubuntu-audio-dev PPA, and they should build RSN. Please test them once they're available.

This bug was fixed in the package pulseaudio - 1:0.9.19-0ubuntu4

pulseaudio (1:0.9.19-0ubuntu4) karmic; urgency=low

  * Remove 0053-fix-sigsegv-module-bluetooth-device.patch, as it did
    more harm than good (reopens LP #437293).
  * debian/01PulseAudio: Fix bashisms, and make suspend/resume actually
    work with sudo -H -u (LP: #432096, #450461).
