I purchased a SBLive 5.1 and ran tests with it in a Dell PowerEdge 1750
(2x2.4GHz Xeon) the last time we had complaints about sound jitteryness
and I wasn't able to reproduce it, even with heavy buildworld load.
Guess its time to pull the card out and give it another try (after I just
pulled it out of the machine yesterday...)
