Every now and again when I switch on my tv there is a picture but no sound. This has happened about 3/4 time over the last few months, and the only way I know of to get the sound back is to reboot the Mutant HD51 box.
Now this is ok for me to do, but my other half would not be able to do it, as she is not as technically minded as I am. Is there any other easier way of getting sound back when there is non when the TV is switched on.

Thanks
