Ok, will default to 8bit mono then. Shouldn't we add some options then to let the user select stereo and other things? Else dsound will about allways use this mode.
My other patch fixed the problem with sample rate conversion (for alsa). If a wrong format was detected the winealsa driver would tell dsound to use a different format. Atleast this worked before Mike's patch. For the alsa oss emulation problem I have a workaround which I will port over and clean up. Basicly it opens the device for about all formats and if opening fails it means that a mode isn't supported.
