I have new PC with Windows 7 and have installed FSX; REX; ORBX; 737NGX.  All works well with good fps.

 

Last week I flew on VATSIM from EGKK to EGCC and return. Multiple air traffic controllers were online and all functioned correctly. Upon landing back at EGKK I switched from EGKK APP to EGKK GND as requested, but could not get voice contact with the ground controller. The radio was set to the correct frequency for ground control - but the voice channel stayed with EGKK APP.  I operated the transfer button to switch the selected and standby frequencies several times   - but the frequency did not switch.

 

At the start of the flight I had selected EGKK GND and it had worked, Throughout the flight I changed the COMM frequency about 7 times. All worked okay. It was only returning to EGKK and selecting EGKK GND again that I had the problem.

 

Any ideas much appreciated.

Could be an issue on the controller's end, or the server. I'd try switching to a freq with no voice (122.8 for example) then to the GND freq. 

VATSIM sometimes has weird issues with voice. It sometimes helps to switch out and back to the frequency. I also had to disconnect from the network and connect again to get it to work (very few times).

Thanks for the tips. I will try next time it happens.
