No "Select Audio Device" panel when plugging headphones, and no sound output to headphones

[Pierre Equoy]

Summary
=======

Internal speakers work as expected, but when plugging headphones through the 3.5mm jack, the "Select Audio Device" panel doesn't show up (it normally shows up to allow user to select what kind of device has been plugged in, be it headphones, microphone or headset). In the Sound Settings, the Output Device automatically switches to "Headphones - sof-hda-dsp", but no sound can be heard even though the vumeter in the Sound Settings moves!

Steps to reproduce
==================

1. Install focal beta
2. Make sure the sound works as expected using the internal speakers and an audio file or Youtube
3. Plug headphones in jack 3.5mm interface

Expected Results
================

- In Sound Settings, the headphones are automatically selected as output device
- In Sound Settings, the vumeter under the Output Device moves according to the sound
- Sound can be heard through the headphones

Actual results
==============

- In Sound Settings, the headphones are automatically selected as output device (OK)
- In Sound Settings, the vumeter under the Output Device moves according to the sound (OK)
- No sound can be heard (Not OK)

Attached are output of `pactl info` and `pactl list` before and after plugging headphones, while playing a tune on Bandcamp in Firefox.

This bug should probably just be about the missing dialog.

The second part:

> In the Sound Settings, the Output Device automatically switches to "Headphones - sof-hda-dsp", but no sound can be heard even though the vumeter in the Sound Settings moves!

is probably better handled as bug 1866194 (which also needs answering please pieq).

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Rex Tsai (chihchun)]

This is a known issue[1][2]. This will remain as a known limitation at the moment - headphone would be recognized as headset, and no prompt to users to overwrite it, and Intel is still working towards a long term fix to it.

@Daniel:

I've tried the workaround I've described in bug 1866194 comment 7, but it doesn't work on this device.

As Rex mentioned, it's probably a known limitation... for the time being, I'll use the HDMI audio output and plug my headphones to my external screen (that works fine).

@Pierre Equoy:

It looks like you are having 2 issues. The Sound selection UI not appearing and no sound coming out after plug-in. Can you have a look at this question https://answers.launchpad.net/ubuntu/+question/690501. Is this the problem you are having with sound. Should I link my question to your bug report?

It seems like its an issue with Dell's hardware and whatever changes were made between 19.10 -> 20.04

[Hui Wang (hui.wang)]

We have a private bug which is similar to it. #1875597

[Hui Wang (hui.wang)]

the first issue of this bug https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1881659 is similar to this one.

[Sebastien Bacher (seb128)]

Is that still an issue with other fixes that landed?
