I did try the mentioned card, getting mine through Newegg.

The card works with the PCI card portion of the M-Audio Delta
1010 system.  This *really* helped my xrun issue.  They went away
completely.  But, mechanically it wasn't so good.  The S/PDIF
connectors of the card that used to stick out the back of the
computer were covered up, and the DB-25 connector barely fit.
Also, the card is pretty wobbly, and there's no way to screw down
the daughter (e.g. Delta 1010) card of the pair.  If this is the
only choice available, it *DOES* work.  But, I'm going solve the
interrupt problem without resorting to this.

I hope this info is useful to somebody.

Cheerio...
