had something similar with wireless card on forum a few weeks ago put back wireless card to the bottom slot on motherboard and turn antenna sideways so the wont send signal to the audio output also if you can chance the audio cable for shielded one
That seems to be what the problem was. I put the wireless card back in and it started to buz randomly again. I disabled the card in adapter settings, and BOOM no more buzzing!
the only problem with putting the card at the bottom pci port is that it's a micro ATX board, and it already is on the bottom slot. I guess I'll have to pick up another netgear power line adapter or just wire my house with eathernet. Or just look into a shielded HDMI cable.
Thanks sooo much for all the help and input. I even called for an RMA number before I posted this thread, but for some reason I never received the email with the RMA info. Well I guess everything happens for a reason.
