I have been using Ubuntu for a while; this is not a new install. The mic worked perfectly in a Zoom meeting yesterday. Today it was unresponsive. In system settings the mic test is also unresponsive. I suspect it has nothing to do with the app.
Found this microphone is not working on ubuntu 20.04 in lenovo-g50-70 and it describes a similar issue on different system. I also ran cat /proc/asound/card*/codec* | grep Codec got the output
Codec: Realtek ALC256
Codec: Intel Kabylake HDMI
Codec: Nvidia GPU 99 HDMI/DPUnlike Abhishek; I have no idea where to begin editing the alsa~conf file. Does anyone have a generic answer, or insight into this?

Wait for the next daily update cycle.
Not sure this qualifies as an answer but; after much research, updating, debugging, infinite restarts, and exploring countless *.conf files... It just started working. I have no idea why it failed, or why it started working again.
--Theory: I also see an intermittent bug in the wifi on startup. I think some resource is being allocated incorrectly. Or unrelated software packages are trying to share something that should not be shared.
I should also note that the sound problem has appeared a few times this past year. Usually after updating the Zoom application. Coincidence? Maybe it's cleanup is removing a critical file that the system needs?
Apologies to the community for my non-answer. I will monitor to see if anyone has more insight.
I appreciate the 'non-answer'. I have this problem too, but am new to the community and cannot upvote due to lack of reputation. Help me out?
But yes, several times I have also noted that the mic works fine (internal to the laptop AND bluetooth headphones) but then some days it just doesn't. Super annoying to sit on a zoom like a dope without a mic and then ask for a minute to boot back to windows...
