Bonanza F33A for X-Plane: radio problem

Hi.

I recently purchased the Carenado Bonanza F33A for X-Plane (I use XP-10).

I am quite new to XP, and this is my first Carenado plane, so probably I am missing something basilar, but I did not find nothing in the various product manuals.

The problem is related to the radio. I tune COM 1 to the desired frequency (for example the ATIS, I tried also with clearance, ground and so on), but I don't hear anything.

I am able to correctly use the radios on the default XP-10 GA aircraft (e.g. the Cessna or the Cirrus), but I have this basic problem with the Carenado Bonanza.

Could you please give some advices to solve the problem?

Thanks.

A.
