Dual processor NT with a SB Live! card? If so, do you have another card that

I've heard not so good things about SB Live on NT with multiple processors.

Options->Plugins->Audio Output
Be default we're using the soundcard output PMO.

The DirectSound PMO should work fine -- the only drawback is that there is
an extra memcpy in there which degrades performance. The way you write data
to direct sound is not compatible with the current buffering scheme that we
have (well, not cleanly anyways), which forces us to use an extra copy. :-(

Sounds about right.

Sylvain Rebaud wrote the DirectSound PMO and maintain that now. I've also
rewritten the soundcard PMO a couple of times, and I'm still not quite happy
with it. :-(
