Hi Azaz,

I'd take a guess that the Pulse configuration is pointing at a card number as these are assigned dynamically - hence when you remove the mic and plug it back in it can get a new card number.

Have you tried specifying the Jabra as your input device by name as described here: https://mycroft-ai.gitbook.io/docs/using-mycroft-ai/troubleshooting/audio-troubleshooting#specifying-an-input-device
