I just set up my game systems to an AV switcher to accommodate all of them, but now I think I have a ground loop that I can't solve that's making (only) the Wii buzz!
Here's my basic setup.
Left Outlet: Grounded power strip, currently just moved stuff as part of troubleshooting so it only has the modem, router, and Xbox 360. Speakers (not used with TV) are plugged into the regular outlet.
Right Outlet: Clock and Lamp. Grounded power strip now with TV, Apple TV, Super Nintendo, N64, Dresmcast, and Wii.
Apple TV and Xbox 360 use HDMI - no problems. Super Nintendo goes in through the cable input - no problems.
Wii, N64, and Dreamcast are set up through this AV
switcher. The N64 and Dreamcast are having no sound or video problems.
The Wii, however, has a buzzing, which sounds like it's a ground loop. I'm not sure how to fix it. I'm sure I can get an AV to HDMI
(since I have 2 spare HDMI ports) but I'd like to avoid that if possible.
Moved all (and only) the stuff on the switcher + TV to the right hand power strip. No luck.
Tried having the Wii buzzing while unplugging various items. No Luck.
Tried the Wii on the regular outlet. No luck.
I can't run an extension cord from anywhere else as they all would cross doorways, including an outside door. I'm also in a rental.
Any other ideas or should I just spring for the HDMI converter?
I'm pretty good with tech stuff, but everything I found about grounding loops is about amps or is too electricity-mumbo-jumbo for me to understand.
