The sound settings don't appear to help and a number of others have also tried this and no success in getting rid of the issue. Also, turning off the surround sound shouldn't be the fix as so many people want the surround on. Thanks for the reply.
I am just running optical audio from TV to Sonos play bar. I have been a Bell Fibe TV subscriber since 2013. This never ever happened with the old pvr hardware. On the new hardware it never happened either until around September. It happens on record...
Same issue here for a few months now. Watch a recording on the new Android Bell PVR box and every few minutes the sound cuts out for about 5 seconds and then works again. Super annoying
