Chromium with USB headset microphone

Question

I've recently installed Ubuntu 22.04 on my Thinkpad T495 and started using my USB headset (It has a jack pin, but with a jack-to-USB converter) in a USB hub.

It works fine in Firefox, Audacity and other applications, but the sound input is not working in any chromium-based app. Neither in Chrome or Chromium Web Browser, nor in Slack desktop app.

I've tried

• configuring ALSA in alsamixer
• pavucontrol
• set the default sound card in ~/.asoundrc
• set the default source and remapping in /etc/pulse/default.pa
• adding slack to apparmor complain
• reinstall slack from snap, and two different .deb file (even apt upgrade slack-desktop)
• uninstall completely chrome and chromium, then install it from snap and uninstall again and install from .deb
• checking ~/.config/Slack/logs for anything related to sound or alsa
• disabling other soundcards
• disabling mic boosts

If I open a chromium app (slack desktop app, slack in chrome, google meets in chrome) and pavucontrol, then on the "Recording" tab the volume meter indicates input from the source as I speak, but the application's (again slack or chrome) indicator is at constant zero.

Slack's and Chrome's sound test gives "Success" for both speaker and microphone, and I can hear the test sounds, but the microphone seems mute.

I checked the alsamixer and pacmd list-source-outputs, and those show the microphone, and it isn't muted, and the volume level is at 100%.

I've tried to plug the headset into a jack slot, but that just didn't work at all in any applications.

Answer 1

I ended up removing pavucontrol, pulseaudio and even alsa, then simply put my headphone into a jack input, then reinstalling the removed packages. I tried without pavucontrol, but it was neccessary to make it work from Chrome.

Since these reinstalls my microphone works fine in Slack and in anything Chromium related softwares. I think the problem could be that the USB soundcard isn't preferred in some components.
