The M-Audio Delta 1010 has good reviews, and apparently works well under
linux, but is pretty costly.

Ok, thanks Lars. I guess I'll be treating myself to an audiophile for
Christmas unless anyone's got a better idea.

nicely
with very few xruns, but won't do any better. The output of the
messages with 32 frames for capture, for example, is:
10:41:35.039 Startup script...
...
configuring for 44100Hz, period = 32 frames, buffer = 2 periods
ALSA: cannot set period size to 32 frames for capture
ALSA: cannot configure capture channel
cannot load driver module alsa
It looks like your hardware simply can't handle buffer sizes that small.
