| Interference coming through speakers
I've got my external SB Live card hooked up per the diagram on this site, and I've done some measurements with REW. But for some reason, when I turn up the volume on my receiver to run the tests, there's a constant interference/static/buzzing noise. This is not the 60hz ground loop hum, it comes through my front speakers as well as my subwoofer. When I disconnect my sound card from the laptop usb port, the noise goes away. So I'm wondering how I would go about getting rid of this noise, if anyone else has experienced this.
Thank you.
