Audio out of sync by 15-20 secs on any TV in my house

The past couple days the audio is out of sync with the video on any channel by about 15 seconds. Both TVs utilize roku. I have 300/300 async fiber that is not having performance issues with anything else.

I change the channel and come back to what I was watching and within 2-3 minutes it occurs again.

Is anyone else having this issue? Thanks
