Thank you reply. My Laptop's specs is here. https://www.acer.com/datasheets/2015/4876/ES1-131/NX.MYKSJ.002.html
My laptop has 4 pole jack instead of 3pole earphone+3pole mic jacks. It is compatible for Apple TRRS 4pole. It works in windows10 perfectly. I have Apple 4pole <-> EU 4pole(Nokia) hardware converter. https://www.amazon.com/Josi-Minea-Headphone-Connectors-Smartphones/dp/B011S8XKTU And I have 4pole to 3pole earphone+3pole mic jack divider like this. https://www.tvps.com/3-5mm-4-pole-jack-y-splitter-plug-to-2-x-3-5mm-3-pole-sockets-cable-adapter/ecs-4pyspc/ And I also have 3pole mic and 4pole plugin-power mic. http://www.edutige.com/etm001.html http://audiotrack.co.kr/en/microphones/292 When I pluged in my mics on laptop jack, it doesn't appear on "PulseAudio Volume Control". When I pluged in 3pole earphone+3pole mic with 4pole-> two 3pole divider, earphone part works only. I searched and found some documents like me. https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1523100 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1821269 Title: [Aspire ES1-131, Realtek ALC255, Mic, Internal] No autoswitch (4-pole combo jack mic doesn't detect) Status in alsa-driver package in Ubuntu: Incomplete Bug description: I use realtek alc255 analog audio jack.
