Help with audio & video playback issues, TV display type recognition & compatibility, HDCP messages, troubleshooting playback errors, advertisements, and resolving power issues.
I recently installed two Roku Express devices and I logged into my AT&T TV app. The sound/picture is completely out of sync and completely unwatchable. I've called AT&T and they told me to do some basic troubleshooting, no solution has worked. Is this an AT&T issue or a Roku issue? Any tips would be greatly appreciated!
