Well, clearly it does NOT work fine, if you can't access the KS
properties of the driver.

I already told you this.
CComPtr<IDirectSound8> pSound;
DirectSoundCreate8( NULL, &pSound, NULL );
CComQIPtr<IKsPropertySet> pKs = pSound;
If the SoundMax is not your default playback device, then use
DirectSoundEnumerate to look for the device description, and pass that
GUID as the first parameter to DirectSoundCreate8.
