Happy New Year. I have the latest beta v2.6.4.2.beta 4b installed, and up to the previous 2 versions ATC recognized my voice communication. Since then I have lost the ability to speak to ATC. I have assigned the PTT button to my joystick (I also checked to make sure it was not bound to another function), and have "Require P2A or Sim Focus" checked under the "Btns" tab in the config. I can can get by using the "Say It" button, but it is puzzling how the voice recognition has stopped working.

You can check if it's the button assignment or not by using the PTT button on the main screen of P2A and see if holding that down allows you to talk to ATC.  

If so, then the problem is with the button assignment.  If not, something else is wrong.  Check the following:

1.    SWITCH SETTINGS: Check to be sure the Power indicator in the bottom left of the main P2A screen is  green.  If not, then you need to turn on the battery switch and avionics switch in the aircraft, or if that doesn’t turn it green, check the 2 options “Ignore Battery Switch” and “Ignore Avionics Switch” in the Config P2A Setup panel.
2.    MICROPHONE: Be sure the mic volume is turned up and the mic is not muted.  Some mics have physical volume and mute controls and it is easy to forget to set  these.
3.    VALID CALL SIGN: Make sure you are using a valid call sign by changing it to the default Mfg: Beech; Tail Number: N431VB and pressing the Save Button.  You can send me a screenshot of this page and I will let you know if there is a problem with the call sign.
4.    VALID FREQUENCY: Be sure you have a valid frequency showing in the Active frequency display.  Open the Radio Panel and check that the frequency selected has a valid controller assigned.  Try swapping the active and standby frequencies a couple of times.
5.    PTT BUTTON: Use the PTT button on the main screen to eliminate the possibility of it being the Joystick button setup as the issue. Also, it should turn green when you press the joystick PTT button.
6.    VALID PHRASES: Make sure the phrase you are using is appropriate for the controller.  “Say Altimeter” should work with all controllers, so use it.
7.    WINDOWS VOLUME SETTINGS: Check the Windows Volume Mixer and be sure Pilot2ATC volume is turned up. (While P2A is running, rIght click on the speaker icon in the task bar and select Volume Mixer).  Also check the volume of the voices in P2A Config.  On the Communications tab of the Sound dialog, be sure "Do Nothing" is checked for when Windows detects Communications activity.
8.    P2A VOLUME SETTINGS: The latest versions of P2A have new volume settings.  The COM Panel that pops up when you click on the Standby Frequency area has a main volume control that controls both Chatter and Voice volumes.  There are also separate volume controls for Voices and Chatter in Config.
9.    HEADSET SOUND SETTINGS: If you are using a headset, Windows may recognize that and put a set of "level" settings on the Levels tab of the Headphone Properties.  To set these, select the Headset in the playback devices Windows Settings and press "Properties". Select the Levels tab.  Be sure all levels are turned up as in this screenshot - notice the Microphone setting here on the Playback device:
10.    ADVANCED HEADSET / MIC SETTINGS: Be sure the Advanced tab of the Properties window for your default recording device has the sound format set to 2channel, 16 bit, and either 44,100 Hz or 48000 Hz (CD or DVD Quality).
11.    STERO MIX: Be sure that you have this turned off if it is an option.
12.    HEADSET AS DEFAULT PLAYBACK AND RECORDING DEVICE: If you have a headset mic set as the default Recording/Audio Input device, be sure and set the Headset as the Default Playback/Audio Output device.  Some users have had their microphone not working because  they set their Speakers as the Playback device.  
13.    NOISE CANCELLING HEADSET: If you have a noise cancelling headset like used in real aircraft to reduce engine noise, these may not work with the Speech Recognition.  Try using a standard PC headset.
14.    DEFAULT COMMUNICATIONS DEVICE: If using a headset as the default Playback/Recording device, be sure it is not also being used as the Default Communications Device.  This assignment of multiple duties seems to cause a problem.  Likewise, be sure the microphone is not assigned to any other duties besides the default audio input device.
15.    GRAMMAR HELP SCREEN AND DIAGNOSTICS: Try using the Grammar Help screen.  
⦁    Press the Grmr Help button to the right of the Flight Plan
⦁    Press the Practice button 
⦁    Take a screenshot of the resulting Message box with the connection information and email to me 
⦁    Try saying "Say Altimeter" with no other words.  It should be recognized.  Let me know the result.
⦁    If not being recognized, press the "Replay" button and see what your voice sounds like.  If no sound, then your voice is not getting through to Pilot2ATC.
15.    SOUND DRIVERS AND ADD ON PROGRAMS - Many PCs come with Sound Add On programs from the manufacturer that are run at startup.  Some of these programs may "Capture" the microphone and prevent Pilot2ATC from hearing it.  Also, some addons may have such features.  Check to be sure there are not other sound programs running.  Also be sure that you have the latest Audio Drivers for your Microphone installed.
16. REMOVE SONIC SUITE Check your PC for a program named Sonic Suite and remove it.  It prevents the Speech Recognition from working.  This is common on new PCs from ASUS and other manufacturers.
17. Sound Bar or Other Sound Hardware AddOns Some users have reported that disconnecting sound hardware equipment like a Sound Bar or external speakers resolved the problem of a Mic not working.
 

Thanks for your assistance Dave. Lately I have been starting P2ATC before MSFS and everything was working except for my issue. I am not sure if starting the program after I start MSFS is the proper procedure, but that is what I did and voila!, issue solved. In any event, I will start P2ATC after the sim loads from now on.
