Hi,
This camera only has a single microphone. How can we make it as a analogue audio output??

I understand that the camera only has a microphone, but the Pi4 recognizes it as a USB Audio Output and disables the audio jack. I just plugged in a USB audio out and this will provide audio output but it still shows the USB Camera as an audio output and the headphone jack remains disabled.

Hi,
From ChatGPT:
To enable the audio jack on Raspberry Pi 4 with a USB camera connected, you can try the following steps:

  1. Check the audio settings:
  • Open the terminal on your Raspberry Pi.
  • Type alsamixer and press Enter.
  • Use the arrow keys to navigate to the USB camera audio output.
  • Press the M key to unmute the audio output if it is muted.
  • Adjust the volume level if needed.
  • Press Esc to exit.
  1. Disable the USB camera audio output:
  • Open the terminal on your Raspberry Pi.
  • Type sudo nano /usr/share/alsa/alsa.conf and press Enter.
  • Scroll down to the section that starts with defaults.ctl.card and defaults.pcm.card.
  • Change the values of defaults.ctl.card and defaults.pcm.card to the number corresponding to the audio jack.
  • Press Ctrl+X, then Y, and Enter to save and exit.
  1. Restart the Raspberry Pi:
  • Type sudo reboot in the terminal and press Enter.
  • After the Raspberry Pi restarts, the audio jack should be enabled.
