Hi
Having a problem with the Dell Latitude 5175 audio coming out of the dock headphone jack.
By default, the dock headphone jack is shown as an unconnected pin, and connecting to it does nothing (does not mute the speaker, no audio out). If I enable this using hdajackretask, the auto-mute now works but there is no audio out. I also found that if I disable the on-board headphone jack, I can get audio out of the dock headphone but it is extremely faint.
I saw there is a model for this that seems related, dell-headset-dock, but it is setting the pin as a microphone not as a headphone jack.
I've confirmed in Windows that the pin I am using is the correct one (0x1a), and its functioning as expected in Windows.
I've attached two outputs of alsa-info... NORMAL is the default output, QUIET is the output after my changes to enable the dock headphone.
NORMAL: https://pastebin.com/f8sTb6EK
Thanks,
Jackson
