--- Comment #7 from Andrew Eikum aeikum@codeweavers.com --- There are a number of audio commits in between those two tags.
It would be useful to get an audio log http://wiki.winehq.org/Sound of a failing session with the latest version of Wine.
I understand it's hard because it takes a while to reproduce. You may want to quit the game if it doesn't happen after a few minutes, to delete the log file so it doesn't fill up your hard drive. You don't need to keep logging after the bug occurs, just a few seconds of broken audio is enough.
When you get a log, we would only need the end of the log starting shortly (say, 10,000 lines) before it starts spamming "underrun occurred".
Is that something you can do?
