Thanks for the info Paul. So do you say the digi96/8 is significantly less 
well supported on Linux than the Hammerfall/HDSP? If so, shouldn't that 
info be on alsa soundcard matrix?

Since the Hammerfall series didn't seem appropriate for my needs (digital 
I/O only, high cost), it seemed that the digi96/8 and the M-Audio Delta 
1010 LT would be good alternatives. Would the 1010 LT have been the better 
choice? What other alternatives are there for hd recording on Linux when 
Hammerfall/HDSP is not an option?

Sound Driver:3.8.1a-980706 (ALSA v1.0.9b emulation code)
Kernel: Linux neurose 2.6.12-oci2.mdk with realtime lsm module and 
PREEMPT/PREEMPT_BKL enabled. Distribution is PCLinuxOS P91 fully updated 
and with the Jack packages from thac 
(jackit-0.100.1-050708.1.pclo2005.thac).

Thanks
