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.

Was the MIC button pressed? Or got turned off accidentally and you didn't realise

If a controller did not log on properly, or select the right voice channel, this can occur.  This happened during the FDX event right after the 777 was released.  GND and DEL didn't coordinate the log on and managed to screw something up.  In the end, they just used non-standard frequencies to sort it out.  That's a VATSIM issue in the end.

 

For what it's worth, there's a function in PMDG Setup > Simulation (last page) that allows you to force the 777 radio to override all other radio functions.  I don't think it would've helped in your case because it was likely a VATSIM client issue, but it's there to try in the future.
