Why will Roku not help any of us with the audio lag issue? There are pages of posts in the TCL audio lag thread asking for help with no recent replies from Roku? Yet, Roku is responding on this forum to other threads. Why???
Re: Why will Roku not help us with the audio issue?
First try power-cycling the TV (actually pull the plug) - and perhaps restarting the cable box too to see if it makes any difference. If that helps, maybe you can find some less drastic way to re-sync.
I have a similar issue on a Sony android TV where sometimes after using a TV app, going back to the cable box has the audio out of sync and found that temporarily switching to a different HDMI input on the TV and back to the cable box would clear it up. Also, if you don't have a surround sound system, be sure the cable box is set to send stereo.
