Unmute seems to be glitchy

Channels playback quality is the best our HD DVB-T2 playback brilliant in both video and audio though our Apple TV thanks.

However little bug..

Shake to mute works great however when we unmute the mute symbol disappears but the sounds does not. We have learned to skip back a few seconds on the broadcast/video and that recovers the audio.

Mine does this, too. I wonder also if an alternate way of activating mute could be added (other than shaking the remote)?

You can mute from the swipe down menu, from the iOS control center remote, and via Bluetooth remotes using the 'm' key. There is also an API (getchannels.com/api)
