Apparent deadlock on playback exit

[mythtv@…]

During video playback, sound suddenly disappears, attempt to exit playback causes deadlock. This issue is intermittent and happens once out of 5-6 videos watched. Video is a recording from HDPVR.

Attaching gdb and then detaching seems to get frontend back to working state.

Attaching frontend log (general,playback,audio logging), and backtrace from gdb.

Thanks for your report. There have been many fixes relating to HD-PVR material in the last couple of months. Hopefully this issue has been fixed.

If you can still reproduce this problem with current trunk, drop a note to the -dev mailing list asking to re-open this ticket.

[Shane Shrybman]

Re-opening for now. Asked reporter to pursue user support for audio issues and to test with latest 0.22-fixes and possibly trunk as well.

[mythtv@…]

After rebuilding the system on a different set of hardware, I cannot reproduce this anymore. Please close as invalid at your discretion.
