Sound broken on some cards

On mid-high level soundcards.
Tried both loadsound/playsound and playmusic.

Tried with both an MBox2 and an Emu 1820m with same results.

All other sound programs from Windows Media Player to Soundforge to Cubase Studio 4 work just fine, so my hardware setup is not to blame.

The only way i get any sound at all is to go into
control panel->sounds and audio devices->advanced
and turn hardware acceleration down to 'none'.
Even then, the sound I get is disjointed, glitchy and unusable. Have tried the other settings (basic acceleration etc) but get silence.

Note : the fact that I can get the disjointed sound means it is NOT a programming error, and that the sound IS loading and playing (to a degree).

I know that BB sound works on a soundblaster audigy and live, and also a Terratec ews88mt. It even works on the mainboards 'built in' sound.

I'm running windows xp sp2 on intel dual core.
Blitz3d version is 1.98

Did you try dxdiag.exe ?

Yes, there are problems with sounds on some soundcards. I've replaced blitz's fmod sound system with BASS system.
BASS works fine on all soundcards.
