Hi! I have EPOX 9NDA3+ motherboard (nForce 3 Ultra, onboard Realtek ALC850 etc.). Everything worked fine until I connected my VCR to PC. Since then, every time I play any kind of sound (mp3, CD, games) I hear very annoying pops. At first I thought this to be the infamous ground loop problem. I searched the net for an answer and found out that these pops should disappear when I remove my VCR from PC which I did but it didn't help. Perhaps there is another solution? I repeat, everything was working fine until I connected VCR to PC! Someone told me to mute Line in, Aux and Phone Line but it didn't do any good. I checked the speakers and wires and they're working fine. Does anyone know how to solve this one? I'd really appreciate it! Thank you!
