I just purchased a 3941X Express 4K and have non-stop humming. Has there been a solution found to this problem yet? I’ve found a few posts but no mention of a solution. I’ve tried different HDMI ports on the tv, powering it by TV USB or a home outlet, even swapped HDMI cable, power cord, and power adapter for known functional ones with no change. SW says it’s up to date - 11.5.0 build 4312-CR. I’ve run out of things I can check so any help would be greatly appreciated.

@OldSchoolHuman-

I don't have any solutions for you, but to help those who might ...

Do you hear this humming coming from the Roku itself, or is it coming through the TV (and/or sound system) speakers?

Thanks Makaiguy. The humming comes through the tv speakers and/or the sound bar. If I mute the TV the humming stops. If I go to another TV input not plugged into the Express the sound also stops.
