Description robert marshall 2016-12-07 20:37:27 UTC

I use bluetooth headphones on a few occasions I take the laptop away from the headset and turn off the bluetooth device within plasma. I return and reconnect the device - which works and the volume control sees the device. But sometimes when I then play a track it appears to play but is silent (nothing on the headphones - or on the wired phone connection). If I then exit amarok to try to sort it out it crashes on exit with the following traceback

Application: Amarok (amarok), signal: Segmentation fault

General Information:
   Amarok Version: 2.8-git
   KDE Version: 4.14.2
   Qt Version: 4.8.6
   Phonon Version: 4.8.0
   Phonon Backend: VLC (0.8.0)
   PulseAudio: Yes

Doesn't appear to be crashing in pulse audio (my main suspect in view of the silence) but maybe something is getting corrupted?

Comment 1 Myriam Schweingruber 2016-12-09 09:43:05 UTC

It is obviously a MySQL error (see Thread 11), but this could be due to a corrupt database. You could do a full rescan, quit amarok and then try again, see if that helps.
Is this reproducible every time?

Comment 2 robert marshall 2016-12-17 21:58:24 UTC

It seems to only happen when I get the audio playback in that broken state. I've done a rescan and am trying to get it to happen again.

Comment 3 Myriam Schweingruber 2017-02-13 18:54:47 UTC

Any news on this?

Comment 4 robert marshall 2017-02-19 13:35:33 UTC

I've not seen it crash again so I guess the rescan fixed that bit, the silent problem is I guess pulse's problem. Close it!

Comment 5 Myriam Schweingruber 2017-02-19 15:14:45 UTC

Thank you for the feedback :-)
