thanx for all the replies
ive switched the front and rear plugs (blue and green) already and the hum remained on the rear speakers...
ive tried unplugging the cordless phone in my room, turning my cell phone off and non of those helped
promedia tech support said to get a new control pod but since they dont deal with canadian customers, i have to deal with Micron in Ontario(Im on west coast, Micron is on East Coast)
it has been about a week since i emailed Micron and I still havent received a reply yet.
I dont think Micron is willing to do anything for me. I guess thats what happens when a company outsource its tech support in its neighbouring country.
