Everytime i start mumble all sounds are getting really weird. I try to
describe it:

When i would play a simple sound like a short "beep", im gonna hear a totally broken "beep" at first and a second echo. But that echo Sound is OK....not broken. Try to image listening music with these effects. When i dont restart my music-player or whatever i use, this effect will remain. When i wait a few MINUTES and then restart my music-player (or game etc.), everything is OK and i can use mumble.
I tried this on natty, oneiric and now precise beta, its all the same. I tried Kubuntu und Xubuntu too.
I tried to configure mumble using ALSA only or PulseAudio only, its all the same.

Maybe good to know:
When i use PulseAudio for AudioInput and i my audio input is too loud (i speak too loud or input volume is too high) the sound will "break" to a noisy sound. Using ALSA fixes this. But maybe this is another problem.
