I have the regions folder in my C:\Pilot2ATC_2021_x64\Sounds\ATC_Chatter\Regions but there is no sound.  I am connected to P2A, have the "Play Chatter" checked,volume is the way turned up, game is connected, I changed the frequency from atis to clr delivery in game on my radio in my PMDG 737 but there is no sound.  There is no flight plan created but I shouldn't need one I don't think.  It shows the location of my aircraft at current airport.  The regions tab is on United States currently.

If you copied all the sub-folders and files from the Stick and Rudder X-ATC-Chatter application's Region folder over to the P2A's ATC_Chatter folder, then the chatter should work.

In addition to the volume control on the Chatter tab of Config, you may need to turn up the volume on the COM Panel that you access by clicking on the STBY frequency on the main P2A screen.
