So I had branched from wine-1.3.30-10-gb0652dd and applied the patch you
mentioned. It fixed HL2, HL, RAGE and - most probably - all other apps that are
affected by this bug.

Yeah, I meant Starcraft II. In case I set emulated Windows version to be WinXP
I've got this messages. Their amount vary from run to run. Applying patch that
fixes _this_ bug reduces a number of this messages. Overall amount is not too
big at all - it is about 2-5-10-15 messages total after I had started up SC2
and played back short game replay (~5 minutes in length). Having windows
version set to Win7 made this messages disappear but I've got SC2.exe crash at
the moment I exit from it which is a subject of another already reported bug.

What I had tracked down is that right after I log in into my account and SC2
opens up its main interface GUI there are several brief (~0.5-1s) pauses
(stutters) both in sound and in visual appearance. Every second time I start up
the game I've got an in-game messagebox telling something like "There was a
problem downloading content, please try again later". I suspect this problems
to be related either to the new SC2 patch I had installed today while were
looking for apps affected by this bug or to the some regression introduced
somewhere between Wine 1.3.8 and 1.3.30 (last time I were playing SC2 for
long-enough period under Wine was when Wine were at 1.3.8). Let's not hijack
this bug report, I would test it a bit later and file a new report in case
there would be enough reasons for that.

P.S. Thx a lot for your hard work over Wine's sound subsystem!
