Code: 
I have hp z240 desktop and I want to record a webcam video.
Cam works fine but external mic does not work.
I am using chrome.
https://online-voice-recorder.com/ I am using to try and record+play.

I hope this is the right place to post.
I can play movies and youtube no problem, I find Fbsd mixer easier than
archlinux.

Any tips on what to tweak to get the mic going?

I see something where you can set variables for Chrome.
When I try, it says camera in use...
Does anyone have and example of setting the recording device for pcm3?

Also I notice realtek on pcm0 says play and rec, could it be that I can record without the external mic??
Any help appreciated.
 
I see something here that might help.... but can't quite get it going.

I'll just leave it here. Chromium works if launching with environment variables explicitly setting which sndio device to use for input and output. In my case I do this in my verison of /usr/local/bin/chrome:

Code:
export AUDIODEVICE="rsnd/0"
export AUDIORECDEVICE="rsnd/2"
mixer -f /dev/mixer2 mic 50

rsnd/0 is the built-in sound card for output, rsnd/2 is the Logitech webcam connected via USB. Mixer setting below sets a reasonable mic level. Now I have Zoom, Teams and Google Meet in FreeBSD. Nice.
 
Code: 
g@dagon:~ $ export AUDIODEVICE="rsnd/0"
g@dagon:~ $ export AUDIORECDEVICE="rsnd/3"

amazingly this worked
I set those and started chrome in same xterm.
