(I reverted the changes for this output as I'm manually setting the value of it after boot).

seem one of the two headphones is dock station headphone/line out as you have dock Mic and two headphones

you have to post output of alsa-info.sh and pulseaudio log to find out why analog-output port is selected when speaker port has higher priority


		device.description = "Built-in Audio Analog Stereo"
		alsa.mixer_name = "Realtek ALC269VC"
		alsa.components = "HDA:10ec0269,17aa2204,00100203"
		module-udev-detect.discovered = "1"
		device.icon_name = "audio-card-pci"
	Ports:
		analog-output: Analog Output (priority: 9900)
		analog-output-speaker: Speakers (priority: 10000)
		analog-output-headphones: Headphones (priority: 9000, not available)
	Active Port: analog-output

You have the "analog-output" port selected, which mutes the Speaker element. Changing the port to "analog-output-speaker" should make the speaker output work.

Changing the port can be done with pavucontrol, for example. Or on the command line:

    pactl set-sink-port alsa_output.pci-0000_00_1b.0.analog-stereo analog-output-speaker

		output:analog-stereo: Analog Stereo Output (sinks: 1, sources: 0, priority: 6000, available: yes)
		output:analog-surround-40: Analog Surround 4.0 Output (sinks: 1, sources: 0, priority: 700, available: yes)

are your computer  Lenovo thinkpad ?

it seem the driver cannot differentiate notebook with dual headphones and dock headphone as surround40 was supported

Yes, I do. I haven't dock the computer nor plug headphones.

it is unlikely to debug if you don't provide alsa-info and pulseaudio verbose log

it use alc269_fixup_pincfg_no_hp_to_lineout to differentiate dual headphone jacks in dell desktop and headphone and dock headphone jacks

this  mean one of the headphone playback switch may need to rename as "Dock Headphone Playback Switch"

any reason why no dock-headphone.conf when there is dock-mic.conf  ?

is it just because headphone and dock headphone share the "Headphone Playback Volume" control

Sorry. I don't usually have much time during the week. Thank you for your time (I'm programmer so I'm aware that it's a 'bit' hard to debug without debug info).

seem bug of alsa-driver

speaker-test  -c4 -t wav -D hw:0,0

should fail with invalid channel count 

because driver assign headphone and dock headphone to multi_out similar to those dual headphones notebook

Sorry - I haven't noticed the question along the comments. I'm using the in-kernel drivers (3.12.something currently).

I still have the problem with 3.15. Should it be reported to alsa developers or is it he problem with pulseaudio?

I believe this is a pulseaudio bug. This probably has the same root cause as bug 74609.

I believe this bug has been fixed in git master. If not, feel free to reopen this bug.
