Buzzing from Roku Streambar
I have seen similar topics but no posted resolution. I purchased the Roku 9102R Streambar in February. It is connected to a Vizio D32f-G4 via HDMI ARC. SN YL005A576666 Software version 12.5.5, bui...
Update: It lasted about 3 days since the last time I had to unplug for over a minute before the buzzing returned. I did as you suggested and moved it to a different (non ARC) HDMI port. The buzzing ceased, however -- as expected -- there was no sound from the TV.
I returned it to the ARC port and the buzzing returned.
I did a "reboot" on the TV itself and the buzzing stopped without having to reset the Streambox.
At this point, I am confident it is the TV causing the issue, not the Streambox. I don't have another TV with an ARC port on which to test, but I'll continue to work with it.
Thank you for all the follow-up!
