Question / Help Unable to hear audio in real time from gaming PC on streaming PC

I am using NDI to send audio/video to the streaming PC and everything works fine except I am not hearing any audio from the gaming PC on the streaming PC. I see the audio bar moving up and down according to the audio from the gaming PC, but the sound is not played. If I record, audio is captured from the gaming PC and played, but for my purposes someone will need to hear the audio as I am recording/streaming on the streaming PC. Does anyone know how this can be achieved?
