Hey,

currently on beta17 and on 16 before, tried the native 64bit client as well, all drivers are uptodate. My voice is more often than not very distorted when launching TS3.
Thing is it goes back to normal when I do some seemingly random things like going to settings > muting mic > testing voice, testing sound playback, switching capture mode from auto to something else and back, restarting TS3...
There's no real pattern and none of these methods work reliably either, so it's some very annoying fiddling.
No errors in the log.
I recently upgraded my hardware (soundcard is still the same) and switched from win7 32bit where this was not an issue in earlier betas.

Please fix this asap and let me know if you need more info.
