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.
