Muhammad: This looks a lot like a PulseAudio bug. Your log continually prints "state 3" which means the device is still "playing" even though we're not providing it with any data. Can you report your PulseAudio and alsa-plugins (called libasound2-plugins on Ubuntu) package versions?
Unfortunately, I had to reinstall Ubuntu for some laptop issues, and I can no longer reproduce the problem. This does seem to point towards an Ubuntu issue rather than a Wine issue, since a lot of updates were installed.
