What doesn't work: Sound. I've got kernel 2.6 with 1000Hz timing fidelity on a 2+GHz machine, and there is an awful scratching noise in every sample. That goes for both the Starcraft music (played off the CD) and the sound effects. The fullscreen video displays without any hickups, and the problem occurs even when the game is idle. So it's definitely not a CPU problem but a bug in Wine's DirectX audio implementation.
In addition to the scratching noises, all sound effects are cut off (faded, it even sounds like ??) prematurely. It's not a lot, but it's definitely audible that all sound effects are chopped in the end, so to speak.
Using Winamp with out_ds.dll (DirectSound), it seems that sounds also start scratching endlessly after doing a couple of "Play/Pause" cycles here.
Also noticeable while doing play/pause is that Wine's DirectSound is not going a very good job, perhaps with mixing, I'm not sure. When starting playback, it does one of several things, but only at the start of playing: - Leaves out samples - "supersamples" (?) stuff, eg. sound volume doubles - Decrease (half?) sound volume
Output with out_wave.dll seems to suffer some of the same problems, albeit they are harder to reproduce:
When starting a sound, a miniscule 'scratch' sound or slightly loudened volume might be heard for a split second, but almost always go away instantly and so is almost inaudible.
Some times, though, it *does* output overlapping sound samples for a prolonged period of time, just like DirectSound does all the time (when/because of some odd fading technique ?).
What it _doesn't_ have is the eternal scratching noise that Wine DirectSound has, which is of course a relief :-).
The audible hiss in DirectSound seems to be http://bugs.winehq.com/show_bug.cgi?id=2211.
Can't find any mention of the DirectSound mixing (?) problems, neither of the WaveOut ones (albeit they are less of an issue).
