microsoft teams microphone not working

i am using arch Linux. my mic runs perfectly well on all my apps ( zoom, ...) but it doesn't seem to be working using Microsoft teams. either the web app(login using Firefox , chrome) or even when installing teams from the AUR. i also didn't found lots of people having the same issue on the arch wiki so i'm posting here for further help. i really appreciate it if someone helps me with that, i'm new to arch. i am using lenovo ideapad 330 . i have installed teams from the aur repo

https://aur.archlinux.org/teams.git 

there is no errors while running from the terminal the command is :

it opens normally. in the device settings in teams the built in audio and mic are selected.
