Hi all,

obviously there is no one on this list who has similar problems? Would
it be a good idea to post the problem into the dev mailing list?

Anyway, yesterday again I made some tests and I think, that the
OSS-output driver of Wine has a bug. Yesterday I used plain OSS (no
alsa, no sound server, nothing) and again Windows Media Player (I use it
to test sound) said it couldn't use the audio hardware. So there
definitely has to be something wrong here.

Any ideas?

Short summary:
Wine at alsa: works
Wine at jack: segfault !! I think this is cleary a bug, or not?
Wine at oss: WMPlayer couldn't use the audio hardware. Displays an error.

System: Ubuntu Breezy (breezy kernel 2.6.12-10-686).
