I almost never use DishHome Interactive but in boredom yesterday I decided to see what was there. No problem accessing it and I played around for a while. The problem came when I exited it. I had no audio when I went back to regular programming. I tried everything to no avail. Then I swapped tuners and there was audio on the other tuner. Swapped back and still no audio on the first tuner. I finally forced a reboot with the power button and that fixed it. Guess I'll keep my hands off the DishHome button from now on. It's mostly a gimmick anyway.
