Just bought Roku Streaming Stick +. The audio has a horrible buzzing sound. Cannot hear the programming . If I increase the volume it does NOT increase the buzzing sound. However when I mute the TV the buzzing goes away. Help!!!
Have you tried switching the HDMI ports used on the TV to see if that resolves the issue. For troubleshooting purposes, have you also tried connecting your device to another TV to see if you are experiencing the same issue?
If the issue is still not resolved, please send me a PM with your Roku account email address, and include the serial number of the Roku device from Settings>System>About. I'll be able to assist you further from there.
