#264: Audio stops after hibernate until closing all programs/connections to PA
------------------------+---------------------------------------------------
Reporter: theg33kb0y | Owner: lennart
Type: defect | Status: new

------------------------+---------------------------------------------------
Since I started using PA (Fedora 8), after all audio programs are closed
and reopened. Below are the steps I have taken to troubleshoot a problem.
There are 10 steps in this example to reproduce the bug. Debug output is
inline between "========" as code blocks. Is this a bug in PA after
resume, or a configuration problem? After an afternoon of research, there
does not appear to be any configuration change to adjust this behavior.
Thank you!

0. start pulseaudio -vvv[[BR]]
1. open xmms, start mp3 playing through pulse audio.[[BR]]
2. hibernate[[BR]]
3. resume[[BR]]
4. xmms has stopped playing at this point. I try to play any track from
the existing xmms playlist, which fails. Each attempt to play a track
results in this debug output from pulseaudio:

5. Repeats of step-4 result in nearly identical output, but the
input/output descriptors increment.

6. Open flashplayer and play pandora.com's interface swf (directly, not
through firefox) - no audio. Output from step-6:

8. Attempt to play another track in xmms, which is still open from before
hibernation. Results in same output as step-4 and does not play audio.

9. Close xmms. Output after closing xmms:

are closed (note the device suspended line in step-9's output) and the
track plays properly.

includes closing xmms after successfully playing an mp3):
