Just got blue sky on tuesday... getting the same ussue as reported in the 2014 forum post on loss off audio. Happens sporadically on multiple channels. Currently watching SLOW WEST on 473 at 12:56am, May 28, 2017 in Fort St John BC. Switched to 474 - THE ACCOUNTANT... also happening there but far less frequent. Super annoying. I rebooted the box both 10 minutes ago and yesterday... no change.
