I have a brand new Roku Express that just came yesterday. When playing media, there is a very high pitch chirp or squeak that is unbearable. It is at random intervals, sometimes a few seconds apart and sometimes several chirps in a second. It happens with hulu, Netflix, and prime and comes through the TV speakers, stopping when the show is paused. We've tried another hdmi cable, both hdmi ports, hooking to power outlet, and using the tv power. Nothing helps or changes it. Otherwise I really like the Roku, but this makes watching it impossible for me and I'm already very disappointed in this company that I can't just contact support directly.
