Ubuntu 15.04 is used in a call-center. Where they are using this PC

enter image description here

Agent have random headphone to listen audio, so they connect or unplug the headphone in the Asus speaker output jack.

The moment they put the headphone jack unplug Ubuntu over-smartly put the headphone volume level to 0% and puts speaker volume level to 100%.

How can i tell Ubuntu to stop doing this auto settings? and freeze it as following setting? So that the headphone is plugged or not plugged i do not care, my setting remain frozen to headphone only?

    Welcome to Ask Ubuntu! ;-) Support for Ubuntu 15.04 ended on Feb 4 2016 so it's now off-topic here too! :-( If you don't like upgrading often, read this – Fabby Feb 05 '16 at 16:44
  • I upgraded into new version now. can you please instruct for the new version how to setup the headphone volume to 100% as frozen? –  Feb 05 '16 at 16:50

    What version did you upgrade to? I'm still on 14.04 Long Term Support, so if that, I can help you further. – Fabby Feb 05 '16 at 16:58
  • YES - i have 14.04 too, 15.10 too, 14.10 too, what-ever you can show i can then interpret it into my 15.04 or 15.10. –  Feb 05 '16 at 17:05

    OK, What's the output to lsb_release --short --codename&&uname --kernel-release and alsactl --version? – Fabby Feb 05 '16 at 19:04
  • Sir, wily && 4.2.0-16-generic and alsactl version 1.0.29 –  Feb 05 '16 at 23:57
  • Its killing my project, as its running in call-center people do not want to open terminal and do command line arguments, they want cake like Windows OS. please advise, how to make the headphone volume level to 100% (in your way, then i can migrate into my versions). –  Feb 05 '16 at 23:59

Try to disable the "automute" control that you see in Alsamixer:
use right arrow arrow key to move to this control, then down arrow key to disable "automute": your speaker should now be independent from headphone jack,
and only controlled by the "speaker" fader (mute it).
