Microphone not available after switching setup

It might be possible to get microphone working after changing location, and audio devices, by restarting audio server

systemctl --user restart pulseaudio

Previous topic from May was resolved by seting the Jabra USB speakerphone as the default-source

Jabra 510 microphone not working

To set Jabra microphone as default-source

pactl set-default-source alsa_input.usb-0b0e_Jabra_SPEAK_510_USB_501AA5DC007F022000-00.mono-fallback

If that device is unplugged to change location, system will use another available source as the default-source

I suggest use this command to find the correct name of the other microphone source

pactl list sources short | grep -v monitor

If the other microphone source is the Logitech headset shown in previous topic, and the source name has not changed

pactl set-default-source alsa_input.usb-Logitech_Zone_Vibe_125_2215MH00URA8-00.mono-fallback

OR

Install pulsemixer to change the default-source
