Yes, it sounds to me like you just had too many interupts going on,
running your AGP card at x4 will generate a lot of interupts and running
your USB sounds device at low latency will generate a lot of interupts.

So my guess is that you could have one of these things going flat out but
not both.

Do USB devices generate more interrupts per period than PCI? I think all
my machines are running AGP x2 at most.
