[ICOM] IC756PRO3 no transmit and receive audi

[George Szymanski]

Thanks for the extra input Stephen.

I'm not sure if the dsp is involved.
One thing I noticed yesterday was that the band edge beep is also
missing. I don't think this goes through the dsp stage?
Anyway, it's another clue!

Thanks and 73 to all
