I have had my sprout for a couple years now, but recently it has two big issues. The first is that when I watch tv, the volumes coming from the tv optic are really low. Like I turn it up really high and its not terribly loud. (this is annoying in that if I change to streaming music the levels become normal again, and it blasts the heck out of it). Playing around with settings on the tv once, I randomly clicked a button, and the volume went up, then after a few seconds went back down again. This is weird.
I would say it was my tv, but I just got a new tv, and its the same situation.
Then to add insult to injury, I have been experiencing the 30 second cutout that other users have noticed. It only happens when watching tv (at these higher power levels). I would assume its a heat issue, or a protection feature, but its unclear which one it is.
