But wine does not support FULL hardware acceleration ( just emulation only) and Vista does not use dsound any more
The winealsa driver supports Basic acceleration (primary buffer is hardware). I believe it's a quirk of DSound in real Windows to always say the primary buffer is in hardware, even under Emulation.
Under Vista/7, DSound is still available, but it doesn't support hardware acceleration without something like ALchemy and hardware OpenAL drivers.
