I have a Lenovo IdeaPad 320-15IKB with Ubuntu 18.04. When I try to use any kind of microphones, the system seems to not recognice them.

I tried with wired headphones and bluetooth (both working on other devices) and both appear in "output devices" from Audio Setting, but in input just appear "internal audio" (the mic of the laptop)

I also check on pavucontrol and it's the same as before.

If I write lspci | grep -A8 Audio returns

I tried add some Codec lines on alsa config (some solution out there) but I think there is no codec for Realtek Generic (thats what says using less /proc/asound/card0/codec#0) or may be is a polite way of saying "I don't recognice your card, sorry" shutting down XD

Does any one knows what could be happening?

PS: Sorry if it's confusing to read, it's the first time I write this much on a forum.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
