It's also a good idea to use OSS or ALSA simply because of some issues across programs and operations trying to use the same driver. I have to use aoss as a prefix for many operations because my system likes to only give sound to one program. Also like before, if you do this, tell winetricks to change to ALSA or OSS, don't use winecfg if you are familiar with it, my sound failed to work until I had winetricks force the change rather than winecfg. You will, however, need to use winecfg to confirm that sound works with the ''test sound'' button.

Alsp, I'm not sure if you have to tell config that osu!.exe or osume.exe has to run under Windows XP in order to avoid an issue I ran into before where it would say I would need to give administrator privileges. Those are minor compared to getting osu! up and running, though.
