I am testing audiocapture and audioplay node on raspberr yp 4B. Here when i tested it by capturing audio on pi and playing in remote computer with audio_play it is playing the audio on my headphone.

But when i run the audio_capture in pi and try to play the audio in same pi with its audio jack. The sound is not comming. When i echo the audio output it is working fine. I also checked the audio output device with comd: speaker-test -c2 -twav -l7 and the audio output is working fine. when i check the audio output devices here is the output:
