I have an accelerated PowerComputing PowerCenter with a Sonnet Tempo ATA66
card suffering from the stuttering sound problem. The AV Optimizer
application from Acard really solved the problem, but just like the
application from Sonnet for their ATA100 card it does lower performance.
A nice touch is that you can turn on and off AV mode without restarting.
Using applications like Freehand while playing songs in iTunes was no
problem, but a disk intensive application like Photoshop felt noticeably slower.
Supplied in this mail are on and off graphics. [performance graphs]
Thanks for producing the Mac-tech site with the most accurate information.
All the best

The AV Optimizer link is now listed in the FAQ's Audio and IDE PCI Controller section. Here's a download link.

"mike -
once again, thanks for a great site and for your prompt response to my
emails and questions...
now - on to the "AV-optimizer" - the thing WORKS!!!!!
i haven't done a lot of testing... but i've been plagued by the dreaded
sound/video skipping/dropout that's been inherent with the older macs and ide cards... i've got an 8500/120 that's been upgraded to a G3-295 using a railgun card. i bought the tempo 66 card and have been using it to drive a
WD 45 gig cavier drive...
up until tonight, if i wanted to hear any "full" song (mp3 or whatever)
without glitches, i'd have to transfer the song over to one of my scsi
drives and run it from there...
but just a few minutes ago, i saw the info about the acard's utility -
downloaded it, ran it and for the first time in 9 months, i've got GLITCH
FREE AUDIO!!!!
.. what fun! now to try some mpg & video that was suffering
the same problems
once again - T H A N K S ! ! ! ! ! ! ! !

As noted here before (above), there is a performance drop with the AV mode enabled however.
