Bug 315663

Application: kcmshell4 ()
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.5.0-23-generic i686
Distribution: Linux Mint 14 Nadia

-- Information about the crash:
- What I was doing when the application crashed:

I was playing with sound settings, trying to get the sound to go out my digal fiber optic cable over to my Onkyo TX-NR509 sound system.  When doing this it crashes this program for some reason.

I have the alsa drivers installed, and I installed built them from the source code.

PS:  You should add Linux Mint to your crash reporting assistant :)

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Control Module (kcmshell4), signal: Segmentation fault
