Start KMix when an audio file is playing

KMix crashes as soon as I switch from a file to another

kmix (4) on KDE Platform 4.8.1 (4.8.1) using Qt 4.8.0

- What I was doing when the application crashed:

KMix crashes regularly when changing streams or the songs are switching.

I don't know if somehow the various output devices I am using are connected. I am using an external sound card and regularly plug and unplug an USB headset.
The crash occurs systematically when changing between the devices.
