 headphone and speaker have to use different audio output if you really want independent headphone in notebook

Sounds works as expected in windows 7. So it should be possible to somehow make it work as expected.

In the GUI audio settings under the output tab, in the "play-sound-through" list, there is one device listed:
When the headphones are plugged it says "Headphones Built-in Audio".
When the adphones aren't plugged in it says "Speakers Built-in Audio".

@Raymond
So ubuntu fails to add the extra audio output automatically?

Hi,

I have the same issue in ubuntu 14.04, clevo W355SSQ.

grep "Codec:" /proc/asound/card*/codec*
/proc/asound/card0/codec#0:Codec: Intel Haswell HDMI
/proc/asound/card1/codec#0:Codec: VIA VT1802

Status changed to 'Confirmed' because the bug affects multiple users.

[Thilo Uttendorfer (t-lo)]

Why is this a duplicate? "No sound after suspend/resume" seems not related to this bug.

Nevertheless, I can confirm this bug on Schenker XMG system on 14.04 and 16.04. There is a workaround described here: http://storax.github.io/blog/2016/04/24/xmg-p505-headphone-jack---sounds-easy/

Would be nice if Ubuntu would detect plugged in headphones automatically.
