Bug Description

I use realtek alc255 analog audio jack. External jack is 4 pole combo(apple type. not europe type.).
When I plug 4 pole mic into jack, It doesn't detect.
So I can't my voice through external mic.

My laptop has internal mic. It belongs to Intel sound(HDA Intel PCH. Audio device: Intel Corporation Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Series High Definition Audio Controller (rev 21)).
Internal mic works well.

For a 4-pole combo jack to work you need:

1. To be sure the laptop's socket supports 4 poles (is there a headset icon next to it?); and

2. To be sure your headset uses the same standard as the laptop. Unfortunately there are at least two different and incompatible standards for 4-poles ("TRRS"):


I can't find any detailed specs or photos of that laptop. If you are sure there's a headset icon next to the port then my next suggestion would be to try a different type of headset (a PC headset instead of Apple, or vice versa).

Changed in alsa-driver (Ubuntu):

Thank you reply.

My Laptop's specs is here.

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.
And I have 4pole to 3pole earphone+3pole mic jack divider like this.

And I also have 3pole mic and 4pole plugin-power mic.

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.
