On my Notebook (with Realtek ALC269VB) the sound over speakers works well until I plugin the headphones, Speakes get muted as expected but no sound on headphones. I noticed that as soon as I plugin the headphones, Alsamixer, Ubuntu Sound Control and pavucontrol switched to 'Headphones' which have no effect (does not really exist). When I switch back to 'Speakers' everything is fine; I can control the sound of headphones. This is a kind of work-around (starting pavucontrol to switch from Headphones to Speakers) but not relly satisfying.
My complete sound configuration and a screenshot of Alsamixer.
You may notice that Alsamixer says 'Intel Cougarpoint HDMI' instead of 'Intel HDA Realtec ALC269VB' what it did two days ago. Anyway, I couldn't find any differences between it.
My question:
In order to easy the work-around: is there a command line option to switch to 'Speakers'?

Pulseaudio always tries to switch to a newly available audio port when it becomes available. To stop this we can edit our
default.pa. This file is located in/etc/pulse(defining settings for all users) or in~/.pulse(to override these settings for a single user). Just comment out this line to stop pulseaudio from switching ports as follows:To take effect we need to restart pulseaudio server with
pulseaudio -k(or restarting our session).
