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.
Your definition is a little bit different
Emulation Forces emulation.
The Emulation setting above forces DirectSound into emulation mode. In this mode, DirectSound applications run as though no DirectSound driver is present. All mixing is done by DirectSound in user mode, and the resulting audio data is played back through the waveOut API
In linux openal is just software mixing of the 16 voices , so full hardware accleartion is impossible
