Hello, AndyH.
Thank you for being a long time customer. I can only imagine how frustrating the audio loss you are describing can be. I'd like to help. There are a couple of things that can impact audio during TV viewing. Many of them are covered here

One thing to check is your cabling between the tv box and your TV. Sometimes reseating this cabling can correct the issue. Some audio settings (such as SAP) can affect the audio you expect to hear. You can find how to check the settings for your particular equipment here
