Ok, I see the problem. And if the mic input is not used as a signal
source but a "silent stream"? That may simulate a PTT function without
hardware muting the mic.

If I want to place two calls - one for intercom (without any muting) and
one for the ATC (with muting) I cannot mute the mic - only the data
stream of the VoIP-session...

We will see. Thanks for your hint! First of all fgcom has to run with
the basic functionality on as many platforms as it can.
