Slight hiccup - I had to reflash my HD-FOX to get it to do anything at all. I've not been too careful about power cycling: I have the HD-FOX hooked up to a Qumi, and because the Qumi has no remote on/off at the moment (very crudely) I have a remote control on the wall socket and just zap the whole lot (note to self: move RC to the Qumi outlet only). However, at first sight the power cycling had nothing to do with the problem. I started up last night and had the vision-but-no-sound HDMI problem. So I cycled through stand-by... and the HD-FOX wouldn't start up again. Whatever I did - reset, stand-by button, cold start - all I got was a green light and the Humax splash screen, going back to black screen and red light. One clue I got was that before it shut down the front panel showed "UPDA". Nothing left to try, I reflashed official 1.02.20 and all was well again.
