Audio out of sync with video on xi tv
Past few weeks the audio has been out of sync with the video on my x1 tv. I have no new tvs or connected device & its intermittent .it off by a few milliseconds causing physical discomfort . I have restarted & refreshed my box several times with no effect. Its not all the time & as far as I can tell not every channel.
Note my tv is a stand alone tv & not connected to an entertainment system or stereo system
