Microphone Not detecting by system

I am using pulseaudio as my sound driver

@Sabbir_Ahamed_Maruf

Sound Server-3: PulseAudio v: 15.0 running: yes
Sound Server-4: PipeWire v: 0.3.40 running: yes

I see many people are using PulseAudio and Pipewire together, so there must be a solution.
Personally, I moved to pipewire only. But you should make sure that at least pipewire-pulse is installed for the complete replacement.
I’m copying below a couple of references for using pipewire, but you can search in the forum (I’m not an audio expert, a normal set-up of audio with internal and an external wired headset with microphone works for me).

Pulseaudio/Wireplumber conflict

Yes. There's no need to have both, and PipeWire is rapidly becoming the better option (for many people it already is). Just sudo pacman -S pipewire-pulse will do it.

Many Audio Issues

Install and run pavucontrol to check your configuration, and make sure PipeWire is actually running (e.g. systemctl --user status pipewire.service pipewire.socket). It looks like you're limited to ALSA, which, as mandog says, doesn't support multiple simultaneous devices. There won't be a tutorial for troubleshooting a specific problem.

For PulseAudio microphone issues maybe you could give a look at the Arch Wiki:
