[alsa-devel] Headphones not detected when using Dell Dock WD15
Hi,
I reported this bug to pulseaudio[1] but after some investigation it looks like the alsa mixer is not working for the dock.
I'll be happy to provide any additional info which might be required (attaching alsa-info.sh BTW). Please add me to the Cc as I am not subscribed to this list

Did you try to update the dock BIOS? The old BIOS on some Dell docks had a few known issues.

I might try. I don't have Windows in the laptop so it might be a little bit difficult.

I tried with a virtual machine but the firmware update program crashes for some reason. Anyway the dock seems to be working fine because the Windows virtual machine properly detects the headphones when plugged in.

Well, it's a USB-audio device and it doesn't give the jack detection control like HD-audio.

Not sure about the next step. Do you need additional information to solve the issue? Are you saying that it's a HW issue and that alsa is not going to provide any fix? I'm a bit confused.

In general Linux USB-audio driver doesn't provide the jack detection control. If any, it's vendor-specific.

The problem is not just that jack detection doesn't work, the problem is that the mixer doesn't work at all:
$ amixer -c1 amixer: Mixer hw:1 load error: Invalid argument
I would expect the USB-audio driver to provide a mixer control for choosing the routing, unless that's implemented in some non-standard way too. As it stands, PulseAudio has no control over the routing, so the headphone output apparently can't be used at all.

Hrm it's not clear to me. The routing among which?

According to Sergio's earlier mail, the firmware has not been successfully updated, so I guess at this point we can blame the firmware.

After I sent my previous mail, I realized that I've been assuming that only the rear output (speakers) of the dock works, and the front output (headphones) doesn't, but Sergio never actually said that. So I was talking about routing between the rear and front outputs, but now I'm not sure if that's the problem after all.

AFAIK, there is no routing selection in the device but only the mute / volume controls. Realtek people told me that the non-working output (one of headphone or line-out) is likely the firmware bug.
Actually, this might be worked around by not touching any mute / volume control. Writing some value screws the firmware, as it seems.

So the problem is that I could not find a way to update the firmware as I don't have Windows on my laptop. I tried using a VM but the update software crashes just after trying to execute it.
