Why do I hear a humming/buzzing noise in my computer-receiver connection?

Question

I have tried creative labs model number ct4750 sound card and soundblaster live (high grade) sound cards in my computer. I have a cable that goes to my yamaha htr-5450 reciever and when i turn the volume up on my reciever i get a buzzing/humming sound. When i listen to music the humming sound is still there. I checked the cables, made sure the sound card is seeded correctly (since i tried 2 diffrent sound cards), made sure all sound profiles are correct and yet i still cant figure out why there is a humming. I would appreciate the help.

Thanks,

Brian

I experienced this problem years ago

In your sound card - reciever connection, the problem could be one of two possibilities:

-Interference from another electronical device around your computer

- No grounding

If your receiver doesn't ground, then that humming/buzzing noise will still be present To fix

this, do the one of the following (depending on how much you're willing to spend):

1 Link a Creative Soundblaster external usb to the RCA out/in converter

2 Choose from many sound cards that give audible stability
