On your NextBox, have a look under "Settings - Audio" and change it to "Other". Perhaps your TV doesn't like incoming DD5.1 signals, which are what most HD channels broadcast.
Edit - I just noticed you're from NB, so there may be a different way for you to access the audio settings on a STB in Atlantic Canada, but you should still be able to set say PCM or "other" instead of DD somewhere.

Lose sound when switching to HD channels
Hello,
I've just purchased a brand new 4k TV, everything is great with standard definition, However when I attempt to watch an HD channel there is no sound, if I shut the tv off and back on there is sound but when I leave the hd channel to watch standard definition there's still sound but if i go back to Hd the sound is gone again.
Its like the receiver is having issues adjusting from standard audio to HD audio, the picture is great and I'm running from Nexbox direct to tv via Hdmi cable.
Any ideas on a fix would be greatly appreciated.

What model TV, also is the Rogers box plugged in directly to the tv using an HDMI Cable, or does it go through a receiver?
I'm assuming you have a Motorola STB. Here's a link for settings:

1. Go into the user menu per the instructions in the second paragraph.
2. Scroll down to Additional HDMI Settings and set the audio for LPCM instead of auto or PassThrough.
