IvanPiacun:
If you have the sound muted on the Vodafone Gen2 Set Top Retail Cloud PVR Box when you turn it off with the remote then when you turn it back on again with the remote the sound remains muted and cannot be unmuted. You then have to pull the power cord from the box after turning it off with the remote, wait 5 seconds put the power back into the box, wait about 30-60 seconds and then turning it on with the remote restores the sound. I believe this is a bug.
@IvanPiacun I believe you would be correct
