[gentoo-user] All KDE-related programs don't play music anymore

[Alexander Puchmayr]

Hi there,

I've got a somewhat strange problem, which occurs on both my laptop and my 
desktop-pc, both running gentoo. From one day to the other, all KDE-based 
music/media player don't start playing music anymore. 
I've tried Amarok, Kaffeine and Juk, and all of them seem to hang when starting 
any kind of music file (mp3/flac/wma). But, strangly, kaffeine plays videos with 
sound without a problem. Also, other programs (non-kde), for example audacity 
and xine, play mp3 files properly. 
In kde's system settings, the phonon configuration dialog play its test sounds 
properly.

Any ideas? Any idea why it affects two different systems pretty much at the same 
time? Any idea why it worked yesterday morning and started to have troubles 
yesterday evening, without having changed anything in the system?

BTW: dmesg shows a lot of lines that might be relevant:
[21219.855176] traps: alsa-sink[12956] general protection ip:7f08486569f2 
sp:7f083fff6b70 error:0 in libasound.so.2.0.0[7f0848600000+ea000]
one per attempt to play anything in amarok.

Best regards
