Looks like an error in the Xine multimedia library.
- Can you reproduce the crash at will repeating the situation ?
Thanks

I normally get no backtrace at all, since Amarok doesn't crash. It just
suddenly stops playing music and shows the error message.

But after todays update to KDE SC 4.3.4 Amarok has now been running for 4 hours
straight without losing the audio device, so I'd say that this bug is at least
indirectly fixed by 4.3.4.

Since Amarok no longer loses the audio device, the bug is no longer
reproducible.

Many thanks!

@Dario: Sorry that I didn't respond to your reproducing quersion. The info-mail
got lost in preparation for the major exam one week later...

cheered too early - Amarok just lost the audio device again; when switching
form mp3 to ogg vorbis.

But the systemsettings dialog didn't crash, so this bug still seems resolved.
