Distortion in Waveout after playing files with AC3 audio

[Sune_S]

Since installing the latest version of BSPlayer, i've had this weird issue on my system: After watching a movie with AC3 sound, all sounds that play via the Waveout driver (like Windows system sounds) become distorted, but only in the right channel!! :?

BSPLayer doesn't even use the Wave device, i've set it to use Directsound.
The distortion stops after a reboot. I use the WinDVD AC3 filter.
I know this is probably not a bug with BSPlayer.

Any ideas? Is there anything i can do to 'reset' the Wave device without rebooting? Anything i should try to re-install? Thanks.
