After a power cut, 24 hrs ago, (with the box being used), we have lost sound on all channels.
Repeated cable checks, box restarts etc. do not fix the problem.
Typing this whilst on a long hold to help line so any thoughts would be much appreciated.
Have you ruled out your TV speakers?
TV speakers were ruled out but just did the HDMI cable in/out thing again and it worked!
Why is that? So annoying and random!
Be good to know for next time.
