Bug Description

Binary package hint: pulseaudio

After upgrading from 9.04 to 9.10, suspend is broken on my laptop (suspend worked fine on 9.04):
*closing the lid fails to suspend
*clicking on indicator-applet-session in the panel and selecting "suspend" fails
*running "sudo pm-suspend" fails

However, running
echo "mem" | sudo tee /sys/power/state
does suspend my laptop

The pm-suspend log file, /var/log/pm-suspend.log, shows:

/usr/lib/pm-utils/sleep.d/00powersave suspend suspend: success.
/usr/lib/pm-utils/sleep.d/01PulseAudio suspend suspend: No PulseAudio daemon running, or not running as session daemon.
No PulseAudio daemon running, or not running as session daemon.
Returned exit code 1.
Fri Nov 6 09:07:03 EST 2009: Inhibit found, will not perform suspend
Fri Nov 6 09:07:03 EST 2009: Running hooks for resume
/usr/lib/pm-utils/sleep.d/00powersave resume suspend: success.

/usr/lib/pm-utils/sleep.d/00auto-quirk resume suspend: success.
/usr/lib/pm-utils/sleep.d/000record resume suspend: success.

And sure enough, the problem is in the file /usr/lib/pm-utils/sleep.d/01PulseAudio. If I make 01PulseAudio non-executable, then my laptop can suspend normally. On my system, pulseaudio is running as user "pulse" (UID 119). If I kill all pulseaudio processes, then suspend works normally. Also, if pulseaudio is running as my regular user (UDI 1000), then suspend works normally.

Are you using a system-wide instance of PA, and why?

Yes, as you can see in the attached file (modified.conffile..etc.default.pulseaudio.txt), pulseaudio was set to start in system mode (I have changed this setting back to the default). I don't remember why I set this option, but it was probably an attempt work around some problem I was having with pulseaudio in 9.04.

Even if this configuration is not recommended, the suspend scripts should be robust enough to handle it (or else this configuration should not be possible).

Sure, there's a bug in the pm-utils script. On the other hand, don't blindly
assume that I can read attachments. This device doesn't allow me to. ;-)

If my previous comment about the attached file sounded snotty, sorry, I didn't intend it that way. I was just trying to point to relevant information in the original bug report.

After reading some more, and comparing the 01PulseAudio scripts in 9.04 and 9.10, it seems that the pacmd command used in the newer script does not work when pulseaudio is run in system mode. Perhaps the get_pulse_users function in the script should just ignore the pulse user? Something like this:

get_pulse_users() {
ps -C pulseaudio -o uid= | tr -d ' ' | sed s/119//
}

This change seems to work on my system: I can suspend and resume with pulseaudio running in system mode, and sound works after resuming.

Hmm, but (getent group pulse) is preferable. Does the following for
the function work for you?

ps -C pulseaudio -o uid= | tr -d ' ' | sed s/$(getent group pulse |
awk -F: '{print $3}')//

The following works (use getent passwd, not getent group):

True, passwd is semantically the correct one. I wonder, though, that we
shouldn't bail on the sed expression, so I've done a bit of sanity-checking
in the pm-utils script (you can double-check via loggerhead).
