Description Hollis Blanchard 2007-09-30 18:48:11 UTC 
Description of problem:
Audio stops while playing Ogg files. The UI is still responsive, but clicking a
button like Pause or Next cause the UI to stop refreshing.

Version-Release number of selected component (if applicable):
rhythmbox-0.10.0-8.fc7

How reproducible:
It has done this about 5 times in the past hour, when playing an album that was
just imported (using the same version of Rhythmbox).

Steps to Reproduce:
1. Insert CD.
2. Click "Copy to Library"
3. Select CD in the library and click "Play".


Additional info:
"rhythmbox -d" provides no unusual output. A DB polling thread appears to
continue functioning fine even after audio stops. Sysrq stack trace is similarly
uninteresting.

sysrq-t output after audio hang
Comment 2 Hollis Blanchard 2007-09-30 18:51:25 UTC 
This is occurring on a dual-core PowerMac G5.
Comment 3 Bastien Nocera 2007-09-30 19:24:30 UTC 
Please test with rhythmbox-0.10.1-2.fc7 in updates-testing. In the future,
please attach a user-space backtrace, I know you kernel guys like your SysRq+Ts :)
Comment 4 Hollis Blanchard 2007-09-30 20:49:52 UTC 
It looks like my yum only found rhythmbox-0.10.1-1.fc7, and it is still
affected. (I assume the -1 to -2 difference is only packaging, so this
information is still relevent.)

gdb thread backtrace

This is the output of "thread apply all bt" in gdb, with some debuginfo RPMs
installed.

backtrace from mp3 hang

Hang also affects mp3 playback, but can take a while to manifest (approx 30
mins this time). mp3 playback also occasionally stutters, but less often than
Vorbis FWIW.

normal rhythmbox thread state

For completeness, this backtrace was generated after interrupting a
perfectly-running rhythmbox.
Comment 8 Hollis Blanchard 2007-10-27 16:59:20 UTC 
Problem does not affect VLC mp3 playback. Since VLC directly uses /dev/snd, that
probably rules out a bug in the ALSA driver, leaving rhythmbox and gstreamer as
candidates.
Comment 9 Hollis Blanchard 2007-12-14 18:44:45 UTC 
I haven't been able to reproduce this problem in Fedora 8.
