From what I can see none of the SoundBlasters support WaveRT, or at least the ones I've tried. However the Realtek ALC888 and ALC898 onboard sound chips do and I have one o these on my motherboard. So I enabled it in BIOS, problem solved.

The first time I installed Pianissimo it just worked perfectly straight out the box. Since then I've tried it on many systems and I just can't get it to work without loads of lag. I now know when it worked it was running on Win7 using WaveRT. But the problem is I have a load of different PCs and lot...
