Suddenly I have Audio sync issues

Re: Suddenly I have Audio sync issues

Some suggest going to audio settings on the box and if it’s set to hd, set it to stereo. I did and it worked for awhile but went out of sync again. I just switch inputs back and forth vie the upper left button on the xfinity controller and that also works.

I have the problem too. Comcast could care less. Switch if you want a fix.

sync (mpeg streams) is up to the 'sink' (in your case a TV) to adjust.  moving the HDMI to a different port as well as a TV firmware update can reet the sync settings of your TV. use your TV's remote and go to the TV menu to the audio section and adjust 'lip sync'. fixed?

Re: Suddenly I have Audio sync issues

I will call the lead tech for the installation of fiber optic in my community. Two techs have been here and I still have the problem. I believe it is a software problem that Comcast will not admit. I will email all the local subscribers and see how it's going for them.

mpeg (the way video is sent digitally) is a set of streams. the TV in your case receives the streams and uses timing markers to be sure video is in sync (there is a normal sync signal and one about 1/2 second later as a backup). use your TV remote and fix it yourself.

Re: Suddenly I have Audio sync issues

The problem has gone away on it's own, I'm suspecting Comcast made a correction.  It has been weeks and the probem has not re-appeared.

Re: Suddenly I have Audio sync issues

I've done that. Have 3 TVs. Problem of syncing on all three.  This is a Comcast problem and they can't fix it for some reason. I will keep complaining and advising to avoid Comcast in the hope they will respond. I am an old school technician and this is a software problem Comcast will not admit to nor able to fix at this time. So Comcast service should be avoided.

For now the problem has stopped, and I do agree it is on Comcast end.  Lets hope it doesn't come back.  Maybe they figured it out and corrected the problem.
