The problem is for sure a local problem on your system. Make sure that your system meets the system requirements on the product page and read the manuals how to operate this aircraft.

Thought I would try Olaf's settings. Both Captains and FO's radio's COM-1 and COM-2 seem to function properly. Just firing it up but will give it a short flight.

The same problem here - only ATC answers can be heard. Also no text for outgoing calls. ATIS also in a loop with the first words of the info. In default A320 no problems.

Yes, we need a list!  This way we, the customers, can take heed of the list and where issues are on the list and complain much if we are unhappy with the list. We shall meet every Thursday before the evening meal and talk of the list and move the items up and downward on the list.  After discussion we shall complain again of the list and the changes made.  Once we grow tired of the list, we will add to the list a demand for another list with a timeline.   Aerosoft, stop wasting time working on the list and make a list of what you should have been working on for us to complain about!  The customers demand it!
