Sound cuts out completely on all stations soon after power on.

Sound cuts out completely on all stations soon after power on. It only has sound for a few seconds. If I power off and back on the sound comes back until we’re done watching. It happens every single time I turn on the TV, no matter how long it’s been. If it’s off a few hours/days. It happens. If I change the input to Roku or others the sound works fine. I’ve replaced the box because of it, and changing the box didn’t fix it. Same issue.

Hello @Steve1399, thank you for visiting our Forum and for the great detail in your post, I can see why this would be something you want addressed. It's odd that when you restart the box it allows you to hear the sound again, but either way, I have your back on this. Do you have any 3rd party audio devices connected to your cable box, or is it straight to your TV? Also, what type of cable do you have connected from your cable box to the TV or audio device?

@Steve1399 If you replaced the box, the cause may come from the cabling, the sync from the receiver to the tv, or the receiver itself. Testing other cables is a good way to narrow down the cause. As well, testing if this happens while directly connected to the tv, or to a sound bar if you have one. Just to test, and see if it's with the service or equipment. Another source to verify basically.

I have the exact same problem.  I just moved into a newly built home, but also had this same issue at my previous home.  Most times when I turn the television on it works fine, then suddenly the sound goes out, but the picture is fine.  I turn the television off, back on and sound returns, then suddenly goes out, over and over again.  When I moved I bought all new televisions, had them connected by XFinity and now I have the same issue.  Given this happens no matter the type of cable used to connect, the type of television, sound bar, no sound bar, and regardless of location in my home or in the city, it has to be an xfinity issue.

@user_m49b17 Thank you for taking the time to reach out to us here on our Xfinity Forums. I can understand how frustrating this is while trying to enjoy you programming. I'm happy to see how we can help. Can you tell me if you had your cable boxes upgraded or changed when you moved? Have you tried using a new HDMI cable? Have you also attempted to troubleshoot via the Xfinity app when the sound goes out?
