Everyone seems to be missing the obvious reason why MMTTY didn't work
as well as the HAL-DXP38, and that is the soundcard. Don't use the one
on the motherboard, in fact, get a decent one with at least 96kHz
sampling rate. I found a Sound Blaster Audigy SE 7.1 Surround
Channels, 96 kHz SR for about $30US online. Now if I can only find a
Linux driver for it. :-( Otherwise I'll have to run Winbloze. :-( :-
