PC to TV through HDMI causing random buzzing?

I been watchin stuff off my laptop on my TV through the HDMI port and the picture comes in wonderful and most of the time the sound comes in crystal clear but sometimes randomly while watching the sound will start to buzz really badly. It lasts for about 30 seconds and then goes away for a while but eventually comes back. Anyone have ny idea what that could be and if so how to fix it?

Check to see if your laptop’s mic is on (if your laptop has one).

Good thought but I don’t have a mic actually. Thanks tho.

could be any number of things. It could be a system fan coming on and you are hearing the interference, it could be a dirty connection (unlikely), it could be something driver related or performance related…

and I dont know of too many lappys that dont have some sort of built in mic these days… you might want to make sure :slight_smile:

I’ll double check and make sure. Thanks for the help guys.
