Hi everyone. I know buzz/hum probs have been asked before but my problem has been ongoing and I can't seem to find a way to fix it. I purchased an Onkyo HT-S660 system a little over a year ago. A few months ago I went and bought a red/white audio RCA cable and a small RCA red/white to headphone plug adapter to hook up my computer to the receiver for playing games, movies, music, and etc.
After hooking it up I noticed that it made a buzz/hum that made listening to anything through my computer a hassle - only at low volumes could I stand the buzzing. I tried to isolate the problem with my computer by taking it apart and experimenting. I went so far as to build a makeshift computer to see if it was the case or motherboard that was causing some problems (it's an old computer).
Turns out it was the power supply touching the sides of the case. Then I found out my monitor was causing the buzzing as well...then the fridge and microwave when in use...then the new mixer I bought a few days ago for my turntables. Hooking up my turntables or cd player straight to the receiver doesn't create the buzz and my cable box and game systems don't seem to be a problem either. I went to Lowe's and got a 3 prong circuit analyzer and it found an open ground in an outlet in my room...could this be the problem or part of it? It seems everything is sounding great unless I hook my computer or mixer up to my receiver and the buzz starts up again. If anyone has any ideas whatsoever on how to fix this I'd really appreciate it.
So far I've tried:
monster power strip
hooking up computer in other rooms via long extension cord
same as above with receiver
same as above with mixer/turntables
rebuilding computer
moving around speakers
My Room Setup:
-outlet #1-
onkyo ht-r500 receiver
power strip
-ps2
-xbox
-dreamcast
-cable box
-sylvania 20" flat screen
-subwoofer
-outlet #2-

-tascam xs-8 mixer
power strip
-400mhz pII computer
-20" flatscreen monitor
-phone
-cable modem
-outlet #3-
open ground...
