Hello,

I have the issue that my microphone is not available after booting my PC (microphone is permanently connected). The source is completely missing:

It would be great if you could help me to fix this issue. I'm glad the provide more information if you need them, just ask for it. Thanks!

Make sure you've actually actively selected the corresponding profile so it gets stored as the default with e.g. pactl set-card-profile or on the configuration tab in pavucontrol before opting for the replug trigger.

Maybe additionally run

sudo alsactl store

once after being in the fixed situation

Thank you! Setting the profile to

output:analog-stereo+input:analog-stereo

solved the issue.
