Can't capture image or audio from Logitech webcam on Ubuntu server

I have a Logitech C500 webcam and I want to periodically capture image and audio from it, so I am looking to write a simple script. My server is a VM on esxi.

Here is the related info:

$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 0e0f:0002 VMware, Inc. Virtual USB Hub

$ v4l2-ctl --list-devices
UVC Camera (046d:0807) (usb-0000:02:01.0-2):
        /dev/video0

then I run:

$ fswebcam -r 640x480 --jpeg 85 -D 1 web-cam-shot.jpg
--- Opening /dev/video0...
Trying source module v4l2...
/dev/video0 opened.
No input was specified, using the first.
Delaying 1 seconds.
--- Capturing frame...
Timed out waiting for frame!
No frames captured.

I also ran

$ ffmpeg -f pulse -ac 2 -i default -f v4l2 -i /dev/video0 -t 00:00:10 -vcodec libx264 record.mp4

but the text output stops after the "libpostproc" line and no file is produced.
Any help?

Does the webcam work in a normal app, like vlc/sane/skype or even Zoom?

The two webcams I used were not sensitive enough to use audio input at the levels required. Zoom or pavucontrol let you see the audio input. What do you see?

My setup is on an Ubuntu server, so no GUI to work with skype or zoom

If you're trying to use X apps without X, I have no advice for you really.

EDIT: The fact that you're trying not to use X shopuld really have been in post #1. Do you have any console onlyh video apps on your server?

Do you have all the audio and video modules for it?

There's a CONFIG_HID_LOGITECH for older devices, but I don't have that enabled. I use VideoLAN. The ffmpeg command works, but the output is really long.
