I just bought a Presonus Firebox recording interface and can't get the dropouts to go away at any setting. I've tried high, medium and low cpu settings on the firebox. I've tried setting the latency as high as 25ms. I've tried shutting down every service on the PC I could get away with. I also shutdown networking. For testing, I'm just trying to play a simple mp3 file using quicktime or any playback software. The file plays but there are dropouts every couple of seconds. Anyway, here's my setup...please help.
HP Media Center PC
PROC - AMD Athlon 64 X2 Dual Core, 2.0Ghz, 3Gig memory
Drive - 250Gig, 7200.
OS - Microsoft Media Center
Recording interface - Presonus Firebox..firewire interface.
