setting up Microphone on opensuse 15.2

My requirement is to be able to use a mic on desktop running opensuse 15.2 for google meet/Teams call etc.

There are literally tons of tutorials out there for ubuntu and a vast majority of them are using gui tools. But opensuse's kde "sound" and ubuntu's gnome tool "sound" are different. I have already tried this with a JBL quantum headphone (mic+headphone combo port, used splitter to connect to mic & line out ports), a generic(read chinese) 3.5mm mic and a JBL CSLM20. I still cant use arecord to at least verify that my mics work with my desktop !

Currently I have reverted my changes and considering Opensuse's relevant wiki page as a starting point.

Here's my soundcard info along with the device which can play a test sound via my speakers (connected to line out).
