Bug 273987

Application: kaffeine (1.2.2)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.7.3
Operating System: Linux 2.6.38-5p x86_64
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
When another application, like mplayer, is using the on-board soundcard, kaffeine displays a message "Cannot create audio output" on startup. When I select a TV channel to watch, kaffeine crashes.

When I start kaffeine while the onboard soundcard isn´t used, kaffeine doesn´t crash, but the other application (like mplayer) cannot use the soundcard before I quit kaffeine.

Kaffeine and mplayer have no problem sharing the same sound card when I use the Soundblaster Live instead of the onboard card.
