glitch with dsound+gfx

[Richard Dobson]

I have a Mystique, on a humble Pentium133, and have not had any audio
problems as such (though I have not been doing anything with Java).
I am however still highly suspicious about MMX, as on a Pentium that
uses the same registers as are used for floating-point. If the audio is
itself using f/p a lot, perhaps there is a clash there. Has anyone
done/know of any tests on this aspect of MMX Pentiums?
