kali linux – No sound output or recording

I have to use Kali Linux for my job. This involves vulnerability scanning using GVM/OpenVAS and remediating vulnerabilities. The software I’m using is only available on Kali repositories. I also need to record some of the process and comment. I noticed that Kali comes with recordmydesktop built in and VLC media player.

I have a freshly installed Kali Linux 2021 on two systems both don’t have sound output through built in speakers or 1/8″ headphone jack. I know nothing about pulseaudio or alsa. I have attempted some solutions to attempt to install alsa-tools, etc (everything from this post: No sound after login – Kali 2016.2).

When I run simplescreenrecord I can see my USB microphone and when I select it, I can see the audio db incoming moves when I speak into it. However, nothing is in the recording, and furthermore, moving the video file to another computer, no audio on it.

Also, no output for audio/videos, etc.

Tried installing additional tools:

sudo apt-get install libasound2 alsa-utils alsa-oss

If your goal is to propose that problems in Kali should not be fixed, then please don’t. I don’t need an answer within the next 20 seconds. If the answer pops up in the next few months, that would be a bonus.
