Today I was fooling around and decided to try out the earjack feature of my Bel 995. I plugged it into the RD, and turned it on. No sound, so I figured the I should just switch headphones, still no sound. Then I unplug it including the headphones and repower the RD. It powers up fine, but with NO SOUND :-(.
The temperatures have risen and almost hit 90 yesterday, but this morning the sound was fine. I have factory reset the RD, and still nothing. I don't see how it is physically possible to blow a speaker by plugging in earphones.
