--- Comment #12 from kolAflash kolAflash@kolahilft.de --- Finally found a workaround.
Using Wine-1.9.11.
To the file /etc/pulse/daemon.conf I added the line resample-method=src-linear
Then restart Pulseaudio. pulseaudio -k pulseaudio --start
Found the workaround here.

But for Ubuntu-12.10 the file seems to be /etc/pulse/default.pa (default.pa instead of daemon.conf).
