I'm seeing a weird problem with my Series4. If I pause live tv for a while, then fast forward to the end of the line (current time), when the signal comes out of ffwd I get video but no audio. Changing the channel brings back the audio, as does pausing for a second then pressing play. I also get audio if I time it right where I press play as it's coming out of ffwd...just wanted to see if that worked while I was troubleshooting. Restarting hasn't helped. Any ideas? Thanks!
