Webcam audio not working on F32

My Webcam has an audio input function. However, when I record a video with it, the sound is not captured. What should I do to solve this issue?

Make sure to switch the audio input to the camera as well as increase the input volume level.
Check out the Settings > Sound, or use pavucontrol.

I did this. There is a red line beneath the audio option whichever option I choose.

Still not sure if I need to buy a new Webcam.
