** Description changed: - SRU information follows: + jaunty SRU information follows: + + Note that this SRU involves two separate bugs, this one and bug 326532. + + Impact: Users who experience problems with PulseAudio often kill it + (using "pulseaudio -k" or "killall pulseaudio", the latter of which is + more reliable). Jaunty's current pm-utils sleep hook looks for the + session-invoked command line. Users who invoke pulseaudio manually, + after killing it, with "pulseaudio -D" (or other variants) do not have + this session-invoked command line, and thus, when they suspend to ram or + disk, the pm-utils sleep hook does not suspend their pulseaudio daemons. + + Note that the use case of killing the pulseaudio daemon and allowing it + to autospawn afterward is unaffected; jaunty's existing pm-utils sleep + hook correctly reaps all pulseaudio instances. This SRU only applies to + manually invoked "pulseaudio -D", "pulseaudio -vvv", etc. + + Resolution: Modify the pm-utils sleep hook to correctly reap all + pulseaudio instances regardless of pulseaudio invocation command line. + + SRU debdiff: + http://launchpadlibrarian.net/25941550/pulseaudio_0.9.14-0ubuntu20.1.debdiff + + TEST CASE: Boot into a jaunty install. In a Terminal, issue "killall + pulseaudio;pulseaudio -D". Suspend to ram, then resume. Note the + inaudible audio from PulseAudio. + + Regression potential: No regressions have been identified in production. + -- + old intrepid SRU information follows: Impact: A portion of users with a default or updated (intrepid-updates) Ubuntu 8.10 install experience inaudible audio from PulseAudio after resuming from suspend-to-ram. This symptom is due to the PulseAudio daemon not having received proper notification to suspend clients and release the sound device(s). Resolution: Configure users' pulseaudio daemons to suspend prior to suspending to ram and to resume after resuming. This sequence is accomplished via a pm-utils sleep hook. The corresponding fixed version (0.9.13-2ubuntu3) is available in jaunty. SRU debdiff: http://launchpadlibrarian.net/20316781/pulseaudio_0.9.10-2ubuntu9.2.debdiff TEST CASE: Boot into a default or updated (intrepid-updates) Ubuntu 8.10 install. Suspend to ram, then resume. Note the inaudible audio from PulseAudio. Regression potential: No regressions have been identified in production. Background information follows: Binary package hint: pulseaudio > aplay squish.au Sonando Audio Sparc 'squish.au' : Mu-Law, Ratio 8000 Hz, Mono [Suspend to Ram/Resume] > aplay squish.au ALSA lib pcm_dmix.c:874:(snd_pcm_dmix_open) unable to open slave aplay: main:546: error al abrir audio: Dispositivo รณ recurso ocupado Then you need to killall pulseaudio for apps that use pcm starts working again. (Question: How you can stop/start/restart pulseudio? In Ubuntu /etc/init.d/pulseaudio script is disabled) If you need more information, please let me know. Thx. ---------------------------------- Hardy Uptodate IBM Thinkpad X41 Tablet pulseaudio 0.9.9-1ubuntu2
