My mic doesn't get detected. I've tried what's said in this post and it worked yesterday but after rebooting I have the same problem again and it is not working (accessing to pavucontrol). I also tried checking alsamixer and everything seems fine and the mic is unmuted.
I use Ubuntu 18.04
This is my data:
