I have installed JAS 10.5.4 distribution and it works great.

Except my firewire audio card (M-Audio Project MIX IO).

The sound glitches, it seems like firewire connection is slow. I don't have that problem on Windows XP installation.

My FireWire card is VIA OHCI IEE 1394.

"About this Mac" displays: "FireWire Bus: Maximum Speed:Up to 400 Mb/sec"

Can anyone help?
