Audio cutting out, submitted diagnostics

Volume keeps cutting out on me today..It seems that during the commercials on a TVE stream, the volume cuts out. I can move forward and backwards on the timeline and it will correct....including any place where volume was not playing.. . example:

watching my show.. commercial comes on... somewhere in there the volume cuts out (seems between commercials is when it starts)... if I backup on the time line and move forward, the volume comes back. running surround sound off.

Run a speed test from the shield under Support. What does it show?

Happened again just now.. submitted another set of diags.
