Is this sound stuttering you're talking about? If so, I've been noticing it too since about 2 months ago. I think it has to do with DirectSound. If you run Steam in a terminal with debug messages turned off, you'll probably see a message that says something like this (taken from memory here):
"This soundcard's driver does not support direct access. The (slower) DirectSound HEL mode will be used instead." > > Just for fun, I reniced all the wine processes down to +15.

You might want to try and get some traces (+dsound would probably be a good start; I suppose someone more experienced could give some others to try) Regards, James > > -J > > AMD AthlonXP 2000+ > ATI 9600XT w/128MB > 1GB System RAM > Mandriva 2006.0, updated to KDE3.5 > >
