I've got a SB Audigy that I'm using, 1/8" jack to rca on my receiver. When i make this connection I get alot of humming. Whats the best way to reduce this? Do I need a better cable from the computer to the receiver. The current cable is 12ft long and was fairly inexpensive. Or is this sound card just not sufficient?

If you have not done so, check your play control board off of the sounds and audio devices and make sure the line-in, mic., aux-in and tad-in are muted. you also my want to invest in some shielded cables

Also try not to have the the volume too high on your soundcard if possible.


Easiest way to bypass the bad DAC on the Audigy is to not use it. Run a digital line from your Audigy to receiver and have your receiver "decode" it.

if possible, plug you PC and your stereo setup into the same power outlet to try and give yourself a common ground. Your humming could be caused by a ground loop. Also, do you have a tuner card in your PC and is it hooked up to CABLE TV? If so you way have a ground loop from the cable company. Try disconnecting the cable feed to see if the hum goes away.


In my case, the only way I was able to complete remove the humming problem was to get a hoontech DB III daughter board for my audigy and use a optical SPDIF connection between my pc and stereo.

Had the same problem, it was a ground loop.


2 methods to correct:


$15 Ground Loop Isolator from Radioshack


or


Buy a cheater plug for your PC that has the external ground, converting a 3-prong plug into a 2-prong. I'm sure I'll get a speach on how defeating the ground on your box is dangerous, but it works & I've used it this way for a year now with no issues - and I do understand the risks.
