Is this sound stuttering you're talking about? If so, I've been noticing

If you run Steam in a terminal with debug messages turned off, you'll

"This soundcard's driver does not support direct access.
The (slower) DirectSound HEL mode will be used instead."

related games (including CS:S) There's bug 3665 that deals with
something a lot like what you're describing, with the HL2 intro video:

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
