I built a PC to integrate into my church sound system a while back, and am now getting around to trying to patch in and use for recording services. Problem is that any way that I try to get an input into it, I get a horrible ground problem (I'm guessing that what it is...speakers buzz and all connected video devices have interferance) Granted, I'm just working with the integrated sound card and I know I'll need a more professional card to do things right, but I would like to connect things as is just to try to figure things out. I've tried coming directly off my mixer with a 1/4 out. Buzz. I've put a direct box in the same line and lifted the ground. Buzz. I've even run RCA outs from a connected tape deck (that has no buzz) and run that to the PC. Buzz. Any way I connect it I get the same result. Is there anything else I can try before I put the $$ down on a different sound card? Also, should I get an internal PCI card, or would a USB card make more sense? I don't need anything fancy, but any suggestions on that would be great too.
