Hi,
What is your default input and output audio device on Windows? You probably have “NoMachine Microphone Adapter” set as a default output device. In this case NoMachine records audio stream from this device and transmits it to the other side, so that is why you can hear your voice on the client side.
If “NoMachine Microphone Adapter” is your only available option for output device you can try to add “NoMachine Audio Adapter”. Please run the following command as administrator using correct path of NoMachine executables, for example:
"C:\Program Files (x86)\NoMachine\bin\nxservice64.exe" --deviceadd --inffile "C:\Program Files (x86)\NoMachine\bin\drivers\nxaudio\amd64\nxaudio.inf" --hardwareid *NXVAC
After that, set “NoMachine Audio Adapter” as the default output and “NoMachine Microphone Adapter” as the default input in Windows sound settings. If you are doing it in a NoMachine session you can just use the command below to respawn nxnode process which will start audio service with new selected default device:
taskkill /f /fi "IMAGENAME eq nxnode.bin" /fi "USERNAME eq SYSTEM"
