I'm using an HP EliteBook 9470m. It has one single combined input jack for microphone and headphone. I get clear nice sound with headphones missing a microphone, i.e headphones with only a three contact jack as shown on the right in the picture below.

When I use my phones headset (four contact connector on the left in the picture below), I get somewhat weak sound. I have to keep pressing the headset's button to get full sound quality.

Audio jacks

I assume Ubuntu does not auto-detect the kind of jack that is plugged in. How do I get Ubuntu to recognize my mobile's headset?

  • My question is similar to this one, except that my laptop has a combined audio jack that should in principle work. – con-f-use Mar 19 '15 at 12:50
  • May be it's a hardware compatibility issue. Try a headset from another manufacture. Also try to insert it partially (90%) – Prinz Mar 22 '15 at 6:31
  • The 90% work. I noticed it before. But it's not a solution. The jack just pops out this way, if I don't hold it in place. – con-f-use Mar 22 '15 at 8:48
  • Does it means that this dialog which allows you to select your headphone type won't pop-up when you plug it in? – P.-H. Lin Mar 26 '15 at 7:31
  • I've never seen it to this day. – con-f-use Mar 26 '15 at 9:27

This clearly have to do with pulseaudio package indeed.
