No, I think perhaps "irq hungry" is a meaningless statement, rather
there's a nasty fight for resources between my AGP Rage card and the
Audiophile, I'm testing this simply by running Jack, and watching the
reports of xruns, the sblive is popping an xruns every twenty minutes, and
then the xrun is tiny like .009 miliseconds, while the Audiophile was
popping a 54 milisecond xrun every two seconds. The whole "irg
hungry" thing is perhaps a misnomer.
