Sound disappears when you change channels from SD to HD channel
We use our retail Youview box everyday and it's normally left on channel 1 (BBC) overnight. 99% of the time, when I get up and change the channel to 101 (BBC HD) everything is hunky dory but occasionally when I change channel to 101 the sound completely disappears.
Changing back to channel 1 doesn't work as the sound still remains off (as do all other channels) and changing back and forth from SD to HD also does nothing.
The only fix is to hard boot up the box by pressing and holding the power button on the front of the machine which then fixes the problem.
As I said above, the only time this seems to be happening is when the channel list is automatically re-organised and possibly when new channels are added. Just before I change the channel to 101 and the sound mutes I do notice that the machine is very sluggish with accepting the remotes commands. Might be linked, might not be linked.
Can you at least maintain the existing retail box; I've given up asking for any new features or even some polish like additional players/apps.
