Is Comcast / Xfinity aware of this? It's been 2 days and no sound for NBC. Same for all our TVs. Every other channel is fine.
to confirm, your set top boxes do not have sound either? did you try toggling SAP on/off (normally off)?
I wanted to touch base before closing out your post.
Did you get the sound working?
I wanted to reach out one more time and touch base before closing out your post. Did you have any other questions?
I am now closing this post out due to inactivity.
Please reach out again if you need any help!
