Audio cuts out on ABC (and only ABC) at the same time each night

[rdefrancisco]

Been a verizon customer for about a month.

We've discovered a very strange problem where ABC (HD and SD) loses all sound at 8 PM EST every night. No other channel loses sound, just ABC. The picture stays perfect, it's just completely silent.

The sound returns after prime time several hours later, but this happens reliably every night, and again, only on ABC.

Anyone experience anything like this? Any resolutions?

This is almost certainly not your problem, but I'll throw it out there because I had a similar problem. My Internet was fine, and all channels except for 4 and 5 (NBC and Fox, respectively, in my viewing area). It turned out to be the ONT. For some reason, it had issues with just those two channels. The technician who replaced it showed me a graph on their laptop showing that those two channels were affected. He said that it would keep getting worse once this started happening. He replaced the ONT and I didn't have the problem any more.

However, in my case, channel 4 was completely out, and channel 5 had excessive pixelization and freezing.  Since yours is audio only and only at certain times of the day, that's not likely it.

You may be right anyway, it could affect only audio as any signal interference could cause either problem. Could be that ABCs prime time shows are using Dolby audio and the system is having an issue passing that on that particular frequency. It also could be just the Fios box itself. I would try powering down the entire system including the ONT, then powering the Fios devices back up one at a time, starting with the ONT and see if that reset helps. If not, you might need a Box or the ONT to be replaced. Also try changing the audio setting in Main Menu > Settings > Audio & Video > Audio > Audio Passthrough to disable and see what happens. Also is the signal going through a receiver or soundbar?
