Unplugging headset with audio panel open mutes internal mic

I've tried to reproduce this bug on a couple of machines.

On Xenial, on a Thinkpad X270 - I don't have access to the "Internal Mic" when a headset is attached. Only a single mic is shown, and when I unplug a headset the volumes are correct.

On an Artful running GNOME Shell on a Dell Inspiron 11 - I do have access to the internal mic while a headset is attached, but adjusting the volumes as described does not recreate this bug.

Seems that it might be hardware dependent as well as a potential u-c-c issue?

Patch from the OEM team to address this issue.

This bug will not happen on Lenovo machines, since the headset-mic on Thinkpad is called Microphone instead of headset-mic.

This bug only happens on Dell machines which can't detect headset microphone from HW perspective, so when a headset is plugged in, a headset-mic and a headphone-mic will be showed in the sound-setting, and the problem only happens under this situation.

BTW, If you plug a headset into a Dell laptop, and a "Unknown Audio Device" dialog (unity-settings-daemon/plugins/media-keys/what-did-you-plug-in) pops up immediately, this means there are headset-mic and headphone-mic on this machine, then you can reproduce this problem on this machine.

I can't reproduce the issue on a dell latitude e6410, is it supposed to happen with any headset?

@Daniel, did you see reports about similar issues while triaging? Do you have hardware that would expose the issue in which case could you maybe have a look?

The attachment "ucc.patch" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

I've tried three different Dells today and can't reproduce any such problem. The internal mic always restores correctly and working.

Tried both 17.10 and 16.04 but it sounds like you mean Unity where the dialog is "Unknown Audio Device". So that's either 16.04 or 17.04.

And no I don't recall related bug reports.

Ethan.hsieh installed Ubuntu 17.10 (Artful Aardvark) daily build (Sep. 13) on steamboat mlk.
This bug can not be reproduced on Ubuntu 17.10.
The settings is gnome-settings-dameon 3.25.92-0ubuntu1.

If it's not reproducible in 17.10 (using Gnome) then at best that's "Fix Released" or "Invalid" for gnome-control-center.

Buf if someone can still reproduce it in 16.04/17.04's unity-control-center then this bug would remain open.

I can reproduce this problem in 16.04 with unity-control-center.

Hui, could you try if that's still an issue on 17.10? (under GNOME and Unity)
Also do you know what hardware is required to trigger the issue?

@Seb, per #8, it can't be reproduced on 17.10. Not sure why we need to test again.

Also, for machine, does the information on #3 and #4 not enough for you ?

Looks like there is some a race issue involving unity-control-center (and maybe caused by pulseaudio too). I suspect that gnome-control-center is affected by the problem too but its just harder to reproduce. I'm stating this because even with the provided hardware, enabling the debug logs in pulseaudio, the problem is hard to reproduce. I'm going to tweet a little bit the proposed patch and SRU it.

The sound panel needs some love I guess. E.g. why is g-c-c deciding which port the system should use after the user unplugs the headset? In my opinion this should be PA's job. g-c-c should react to changes notified by PA and "update PA status" just if there is an user interaction with the GUI.

Basically something like that: http://paste.ubuntu.com/25824913/. This makes more sense to me. I cannot see any regression. @Seb, @Will, @Yuan-Chen what do you think?

Tested the patch in #14, it works.

Thanks Andrea, the changes looks good and I'm preparing the SRU upload

Hello Will, or anyone else affected,

Accepted unity-control-center into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/unity-control-center/15.04.0+16.04.20170214-0ubuntu2 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-xenial to verification-done-xenial. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-xenial. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

I can not reproduce this bug with the unity-control-center 15.04.0+16.04.20170214-0ubuntu2 on DELL Latitude 7490.

Were these tests, from the bug description, also performed with the new version of unity-control-center?

Regression Potential
===================
- Make sure that plugging/unplugging headphones does the correct thing.
- Make sure that manually selecting an headphone actually switch mic.
- Please also check that output sound works too.

@Brian,

This is from OEM team.
We had verified the unity-control-center 15.04.0+16.04.20170214-0ubuntu2.
This bug can not be reproduced with the unity-control-center on -proposed.

I'm sorry, we seem to be miscommunicating.

It's great that you verified that the bug is fixed. That is, that the internal mic is muted if you unplug the headphones while the control centre is open.

There were other concerns about the SRU though - specifically, that the following items *also* be tested:
- Verifying that plugging/unplugging headphones does the correct thing.
- Verifying that manually selecting a headphone actually switches the mic.
- Checking that output sound works too.

Were those verifications done, in addition to verifying that the bug cannot be reproduced?

@Chris,

I verified below check items on DELL Latitude 7490:

- Verifying that plugging/unplugging headphones does the correct thing: Pass
 When plugging a headphone, the Unknow Audio Device dialog will pop up. And, the headphone works fine. When unplugging the headphone, the device will be remove from the Settings list.
 When plugging a headset, Unknow Audio Device dialog will pop up. And, Both input and output function works fine. When unplugging the headset, the device will be remove from the Settings list.
  When plugging a microphone, Unknow Audio Device dialog will pop up. And, the microphone works fine. When unplugging the microphone, the device will be remove from the Settings list.

- Verifying that manually selecting a headphone actually switches the mic: Pass
 When plugging a headphone and switching the input device manually, only Internal Microphone works. The "Headset Microphone" and "Microphone" do not work.
 When plugging a headset and switching the input device manually, the "Internal Microphone" and "Headset Microphone" work. The "Microphone" does not work.
 When plugging a microphone and switching the input device manually, the "Internal Microphone" and "Microphone" work. The "Headset Microphone" does not work.

- Checking that output sound works too: Pass
 When plugging a headphone and switching the output device manually, both the "Speakers" and "Headphones" work.
 When plugging a headset and switching the output device manually, both the "Speakers" and "Headphones" work.
 When plugging a microphone and switching the output device manually, only the "Speakers" works. The "Headphones" does not work.

@Brian and @Chris,

The "Regression Potential" items have been verified.
Could this unity-control-center in -proposed be SRU?
