Comment 6 for bug 1251127

HP desktop pc with audio line-out / headphone jack in front and rear AND a built-in mono speaker.

Hardware: 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02)

Debian wheezy stable system with pulseaudio 2.0-6.1

With alsa there is a ""Simple mixer control 'Independent HP'" if set to
  * "Enable", sound is /only/ audible through the built-in speaker
  * "Disable", sound is /only/ audible through the connected headphone/line-out

With pulseaudio (thanks a lot to poljar #pulseaudio IRC !):
 (1.) If I unplug any line-out audio cable aka headphone cables, then
      * pactl set-sink-port 0 analog-output-headphones
        Makes sound only be audible through the built-in internal mono speaker
      * pactl set-sink-port 0 analog-output-speaker
        Makes no sound audible (which seems to be exactly how it should be :)

 (2.) If I plug an headphone cable either rear or front, then:
      * pactl set-sink-port 0 analog-output-headphones
        Makes sound /only/ be audible through the plugged headphone/line-out
BUT:
      * pactl set-sink-port 0 analog-output-speaker
        Makes sound /only/ be audible through the plugged headphone/line-out TOO

<poljar> statement: that sounds wrong, analog-output-speaker should either tagged as not available if the hardware prevents it to output to the speaker while something is connected or it should work, so feel free to report a bug

I created for both cases (1.) and (2.) the pulseaudio-output and the client-output. I hope you find them useful. Please let me know if you need anything else.

The system is a headless server system.
pulseaudio is running as user pulse

To get the pulseaudio-output it ran like this (debian default with changed --log-target and added -vvvvvv):

/usr/bin/pulseaudio -vvvvvv --system --disallow-exit --daemonize --log-target=file:/tmp/pulseaudio.log --high-priority --disallow-module-loading=1

So unter pulse I did not find any way yet to use the built-in speaker for sound-output when I have a headphone/line-out plugged.
Even though under alsa I am able to toggle the output to come through the built-in speaker and with or without a headphone/line-out plugged!

This is bugging me, because I have my stereo plugged all the time to the system, but it ONLY gets turned on, when I need it. So important system notifications should be played through speaker.

Please help :)

Thanks a lot in advance !

Tormen.
