4K Thursday night football no audio

[griam01]

Tried to watch Thursday night football in 4K and the video was slow to load (*** across the screen) and when it did load the video there was no audio. I have watched 4K on the X1 box for Netflix and Amazon prime shows, but don’t think I have tried any regular stations. Anyone else have this problem?
