Comment 25 for bug 1873384

I've installed Ubuntu Desktop and now I find out the problem's temporary solve. Please someone can notify the teams that can solve this problem.

In Ubuntu Desktop, when I plug in the headphone(headset actually, it have speaker and mic and can work properly on mobile phone, one 3.5mm jack), the pop-dialogue show up and give me 3 choose items-------Headphone Headset and Speaker

When I choose the headphone item, my headset speakers can work properly. I didn't test the mic because my laptop have a build-in one.
When I choose the headset, the problem shows up, my headset can't work.

In KDE Desktop and Xfce, they both use PulseAudio Control Panel. PulseAudio detects headphone automatically without pop-up dialogue, and the problem shows up.

Maybe the PulseAudio detects the headset correctly, but it treat the headset as old fashioned 2 x 3.5mm jacks kind. Now the new kinds of headset have only one 3.5mm jack with speaker & mic channel on it. My Inspiron 15 Gaming 5577 have the 2-in-1 3.5mm jack hole so when system use old fashion mode it can't work properly.

It can also explain why it can work in headphone mode. Headphone mode is compatible with the 1 jack headset but can't use headset's mic.

Suggestions: Provide KDE and Xfce4 Desktop environment 'Headphone plug-in' pop-up dialogue so that we can choose 'headphone'compatible mode at least. Separate headset mode into '1 jack headset' and '2 jack headset' mode to make headset work properly in different platform.
