    Turtle Beach Santa Cruz Sound Card GIVES me a ground loop?

    I've got a turtle beach santa cruz PCI sound card and absolutely love it.......except for one thing. Before it outputs sound, there is a terrible ground loop.

    For example, I get in the car, start the computer (and the car) and there's a ground loop. A REALLY bad one might I add. Once windows boots up, the ground loop GOES away PERMENANTLY!

    Kinda seems like the op amp built onto the sound card is disabled until the card is fully a zero-bit mute circuit .....well I hate it.

    Any ideas? Thanks ....oh and I've tried a ground loop isolator - didn't help.

    ground your sound card and also ground your PSU to the same spot on your cars frame. If you use an inverter.. use that grounding point

    Like hijink21 said, make sure your sound card, amp, etc are grounded.

    I have a santa cruz in my home computer, and once i didn't screw it in properly to the computer case. After i switched my amp on it buzzed like crazy. It also buzzes a lot if the ground connection's dodgey.

    Might be that the op amp isolates until it initialises? I guess if grounding doesn't help you could put a dummy load on the amp...
