No sound output through docking station headphones jack for Dell Latitude E5450

[mathematatin]

1) Release: 15.04

2) I do not know the package or version.

3) Expected: I expect sound to be output from the speaker that is connected to the headphones jack of my docking station.

4) Actual: No sound output at all.

I have this problem with my new computer: Dell Latitude E5450/5450 (Late 2014) Service Tag: 4W7RQ32. I can confirm that the docking station and speaker both work, as I did not have this problem on my older Dell Latitude E5420 (Early 2011) Service Tag: 1WW25S1 running Ubuntu version 14.04LTS

The icon on the docking station looks like headphones. It does *not* look like a headset or a line out. Attaching image.

if it is dock line out, look like you need to add

[Jack Dock Line Out]
required-any = any

otherwise you need to use hdajackretask to change dock line out to dock headphone

[Raymond (superquad-vortex2)]

why there is dock-mic.conf but no dock-headphone.conf nor dock-lineout.conf ?

do pulseaudio need to support dock line out ?

I have a Dell D630 Latitude laptop plugged into a Dell PR01X port replicator/dock station. I have been struggling with this problem, too. I solved my problem by changing the configuration in "Pulse Audio Volume Control" from "Analog Duplex" to "Digital Stereo (IEC958) Output + Analog Stereo Input". Playback through the audio headphone jack in the dock station works.

[Eric Lee (hotelterminus)]

Thanks Larry, that's so counter-intuitive I never thought to try it but now I have sound through the dock analogue jack.

[Moe Zarella (moezarella1337-deactivatedaccount)]

Larry's solution works, but the downside is the laptop's internal headphone/mic jacks and speaker is still muted when you undock it, unless you switch back to Analog Stereo duplex manually. This was tested with xubuntu 16.04 (x86) on a Dell D620 (Sigmatel Audio). Has anyone found a solution to let the laptop switch between outputs automatically? It even works with Win XP...

Thanks in advance.
