My Roku 4802R worked great until the other day. Audio cuts out like a bad signal on a cell phone. It’s on every channel and even the clicks you hear when scrolling the menus also cut out. The screen also flashes/glitches about every 30-45 seconds. 
I have switched HDMI PORTS
Switched HDMI cables.                                     Reset my modem/router.                             Unplugged Roku.                                          Unplugged the TV.                                             Internet connection speed is great              Software is up to date                  Everything WAS working fine.         Nothing changed on my end. 
I only have the problem when using Roku.
