I have a TRSS headset with earbuds and a microphone. The speakers, internal mic, headphones work fine but when I select the microphone of the headset, the headphones stop working(no sound) and they turn into the microphone(speaking into the earbuds records voice).

What kind of connector does this headset have? Is it a standard 3-pole 3.5mm male connector, or something else? Do you have this problem plugged into another device? Does your soundcard jack support headsets like this (some may only expect sinks, not sources connected to it)? What kind of device are you plugging it into?
That pacmd output is just for your soundcard, it doesn't really tell us anything about what's plugged in. Have you tried selecting the headset in pavucontrol? It could be the wrong thing is selected, and that's why it's behaving poorly.

There are basically 2 TRRS standards CITA and OMTP https://en.wikipedia.org/wiki/Phone_con … _standards.
Maybe you have a mismatch between computer and headset. Although I would expect it to be permanently at fault if this is the case.

Headset has a 4-pole 3.5mm male connector. No the headset(both headphone and mic) works perfectly on android and another laptop. The soundcard jack has the symbol for headset/mic(h/m). Its a notebook specifically Asus x200ca.

Just tell me what to post I'll post it.
I have pavucontrol-qt installed and In the output section their's => Port: Speaker and Headphones and Input => Internal Microphone and Microphone.
Everything works as expected but selecting Microphone stops the output of the headphones and turns them into Microphone.
Same with alsamixer.

I'm not sure but the headphone uses OMTP standard.

I think your headset is CTIA (not CITA sorry) as it is advertised as being apple compatible, also it works with android (most likely CTIA). For the laptop you would have to ask ASUS as i cannot find detailed information about it.
It would be a good idea to test with different headsets or adapters (split or CTIA to OMTP).
Or you ignore all that and workaround it by buying a USB Soundcard with TRRS output.

I bought a USB Soundcard with TRRS output everything works fine thought microphone input is a bit laggy and wired maybe something to do with configuration.
But the problem is not with the standards(CTIA or OMTP). The only difference between CTIA and OMTP is that the Ground and microphone pin are interchanged. But my problem seems to be that the left and right channels are being recognized as the microphone. I think the driver(snd_hda_intel) is at fault here.
Even though I have a workaround I would still like to resolve the problem. So any help is appreciated.
