--- Comment #5 from quasi-anonymous user from bugmenot.com winehqbugs@bugmenot.com 2010-11-02 14:36:43 CDT --- Interesting. I can confirm that sound works as it should if you use ALSA. I did try setting OSS in winecfg earlier and it did not work. Switched my Linux to ALSA to test this.
It still crashes if I try to do things though. For example removing a track from the view in the bottom middle (rightclick->delete). So this only helped remove that other problem.
Your crash log looks iffy... the stack shows it's already in ExitProcess?
I am not sure what that means, but maybe my report was not clear enough. Mixmeister crashes and notices it itself. It displays a "Submit Error Report" window then where you can choose to send a report. Pressing Cancel will not get rid of it. So I am not sure where Wine's backtrace comes into play (I am clueless about those things, more a user than programmer really).
