For the record, I (and Aaron I believe) do not own the 'HDSP', which I think is the PCI card that works with the DigiFace & MultiFace. (Others might have a different opinion of what the 'HDSP' is. Maybe it's just an acronym for the 'Hammerfall DSP' which is only a product line name and not an actual product.) I own an HDSP 9652. This problem does sound a bit like my experience with rev 68 firmware on my HDSP 9652 with the unpatched CVS 0.9.6 driver. Please, to everyone, try to give the complete name of your hardware as the solutions for the HDSP 9652 are completely separate from the HDSP/DF/MF solutions which are completely different from the HDSP 9632 also. what a mess, 'eh? ;-) - Mark
