After my failed attempt to do a regression test, I went back to wineconfig to check the audio input driver, I find that now there is only one, pulseaudio, which wasn't on the list before I started the regression test. Have the wine audio drivers been changed somehow? Could this be the problem?
I assume you are using the Ubuntu Wine package. The Ubuntu packages contain the unofficial winepulse driver as well as changes to dsound that are not part of plain Wine. You need to test this in unmodified Wine.
