[arm-allstar] fob

[Ken]

Yeah - in the early days I burned out the input of a fob. It's easy enough
to do.  If you attached an electrolytic capacitor that had, say, 12 VDC on
it, that would likely be enough.  Sticking the fob on your laptop is an easy
way to test it for input and output ... no fancy test equipment required.

Joe,

 Obviously you have an audio problem. A scope would fine it in an instant
but you could signal trace with an amplifier and speaker. If audio is
getting to the FOB chip then you might have a bad FOB. It has been known to
happen. The FOB is working with outbound audio? The FOB green LED is
blinking properly?  Having no audio at all with rxboost=1 and levels turned
up to max would possibly indicate a short somewhere in the audio path.
