Speaker Hum using ROKU Player


Hire an electrician.

Not joking. Humming is very difficult to solve. In the olden days of 2-channel analog audio, one would say, throw an in-line ground isolator in there and be done with it, but these days with multiple other types of hookups, arrrrggghhhh.

Google and try some of things people have gone through.
 
If it's a ground loop type "hum" it can be very easy to solve. You just have to try a few different things like trying a different outlet. Unplugging stuff and replugging in components one at a time. Or even using a 3 prong to 2 prong adapter, it just depends on what's causing it.

Happy listening, the Prisoner...
