The PC and TV are on opposite walls so they are about 12 feet apart. so they can't use the same outlet. The PC is plugged into a uninterrupted power supply which has the three prong outlets and it is plugged into a three pronged outlet which means it should be grounded.

hi,
connect the two units to the same power outlet from the wall.
Maybe turn around the plugs for one of the units.

Hi,

are you connecting to a desktop computer?

You might try grounding your machine if this is the case.

I am wanting to run a patch cord from the headphone jack on my TV to my PC
to record some shows but there is a hum. I have Comcast cable. The patch
cord is actuallly two cords with male plugs on both ends and a connector
with two female plugs.

When I put headpohones in the jack there is no hum.

Is there something I can do to get rid of the hum?

Thanks,
Dean
