Ok I have a turtle beach santa cruz sound card and my computer is a dell dimension 4300. Now what I want to do is hook up my stereo receiver to my computer to play music through the stereo. I use the stereo plug to phono plug cord and there is feedback in the speakers. Now I bought a better cord that was sheilded and there is still feedback so I tried moving the sound card away from the other card to decrease interference. Well the feedback was still there, so I started unplugging stuff. I tried using different power cord for my computer and making sure everything is grounded. Still getting feedback. So the next wire that I unplug is my computer monitor. The feedback goes away. So problem fixed my monitor is old just need a newer model. Well I tried my roomates flatscreen monitor that is a month old. Feedback is still there when i try the new monitor. So I unplug the new monitor and plug my old one back in and of course my next guess is the video card. So I am unplugging everything so I can open up my computer. Well I unplug my monitor and I don't know why but I just press the plug to the metal on the back of my computer and THE FEEDBACK IS THERE AGAIN. I don't know how to get this feedback to go away! This makes no since to me PLEASE HELP
sidenote i get this feedback even when the computer is off the monitor plug just has to touch the computer metal and the feedback is still there.
