My headphone - boAt Rockerz 510
here's pactl list card

i've found that i have these two input devices in pauvcontrol

The device with monitor in start (Monitor of boAt Rockerz 510), is mistaken for microphone by all apps, whenever an apps chooses it (automatically) , the currently playback audio (say a yt video playing in background) gets picked into the specific app as a mic input.

but if i manually switch the input device to boAt Rockerz (without the Monitor in initial name), the automatic profile switching takes place in my system.

the even after the profile gets switched, the audio from mic get's picked by the application...

Is there any way to stop the audio from the output to get routed to the monitor of headset..
or is there any way i can set my default mic to Headset...(not the monitor)

Note:- this may be device specific issue, but any help is appreciated
thank you

Well, the green checkmark in pavucontrol is what sets the default input device. What you're saying is that even though the first device is set as default, any application will use the monitor device (or even set it as default?)? It looks like you're using PipeWire which used to have all sorts of trouble with remembering defaults. Did you check its logs yet?

idk how to check logs any help would be appreciated

Probably journalctl --user -u pipewire.service.
