The line-out on the Dell Dock station can't work

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1806532

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

This bug also needs to backport 3 patches to alsa-lib of cosmic and bionic, here is the debdiff for alsa-lib cosmic. Please review it, if it passes review, please help enqueue it.

thanks.

This is the debdiff for bionic

And the debdiff is generated based on bionic-proposed branch of https://git.launchpad.net/ubuntu/+source/alsa-lib

thanks.

And the debdiff in the #2 is generated based on cosmic-proposed branch of https://git.launchpad.net/ubuntu/+source/alsa-lib

Thanks for the work, it looks like 0011-conf-ucm-Dell-WD15-Dock-Fix-incorrect-device-names.patch and 0012-conf-USB-Audio-Add-Dell-WD19-Dock-in-the-IEC958-blac.patch were commited after 1.1.7 and is not in disco though so they need to be added there first before we upload the SRU

The cosmic debdiff looks fine, I can upload that once disco has been updated. Can you work on the debdiff for disco as well?

@seb128,

OK, got it. Before I upload the debdiff for cosmic and bionic, I tried to generate debdiff for disco too, but it always failed when I ran "debuild -sa -S" for disco.

I am trying to generate the debdiff for disco now. Will upload it soon.

thanks.

Ok, let me know what error you get/if you can help. Note that the first patch is in 1.1.7 so you don't need it, also you might need to use 'update-maintainer' since we are adding a diff ... if you give your error/log I can try to help you

This is the debdiff for disco.

I installed a disco daily build through docker, then generated the debdiff under disco, there is no any errors when running "debuild -sa -S".

thanks.

Thanks, that looks good. I've merge proposed those changes to Debian since we are in sync it would be nice to stay this way, https://salsa.debian.org/alsa-team/alsa-lib/merge_requests/1. I'm going to upload to disco meanwhile so we don't block on them to merge it.

@Hui, could you give some details here on what's the status of the kernel patches. Are they in cosmic and/or disco yet? Do we need to block the alsa SRU on those bits to land to be able to verify the change works?

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

@Sebastien,

The kernel patches for cosmic and disco already got ack from ubuntu kernel team, and they are enqueued in the next release of kernel.

And it is safe to SRU alsa-lib first even without kernel patches. If the kernel doesn't contain those patches, the alsa-lib will work as before, the new added patches for alsa-lib will not introduce any side effect.

And after the new alsa-lib is ready, I will build a kernel myself to verify it if the ubuntu formal kernel is not ready.

thanks.

Hello Hui, or anyone else affected,

Accepted alsa-lib into cosmic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/alsa-lib/1.1.6-1ubuntu1.1 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-cosmic to verification-done-cosmic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-cosmic. In either case, without details of your testing we will not be able to proceed.

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

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

The build failure for cosmic and bionic (after applying the debdiff of #2 and #3) is because I forgot to add one more patch to add this ucm to configure.ac.

here I fixed it, and generate an incremental debdiff for cosmic (since the debdiff of #2 is already merged to cosmic-proposed branch). If need me put this debdiff and the debdiff of #2 into one debdiff, let me know.

thanks.

This is the incremental debdiff based on #2 for Cosmic.

This is the debdiff for bionic, it is not an incremental debdiff (since the debdiff of #3 is not merged to bionic-proposed branch yet), this debdiff will replace the one in the #3. It fixed the problem of forgetting to add dir in the configure.ac.

The verification of the Stable Release Update for alsa-lib has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

Hello Hui, or anyone else affected,

Accepted alsa-lib into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/alsa-lib/1.1.3-5ubuntu0.2 in a few hours, and then in the -proposed repository.

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

Could you please add some details about the verification process for bionic rather than just switching the tags?

enable the bionic-proposed repository
sudo apt-get update
sudo apt install linux-image-unsigned-4.15.0-44-generic

sudo apt install linux-modules-extra-4.15.0-44-generic
sudo apt install libasound2 (updated to 1.1.3-5ubuntu0.2)

Then reboot and plug the dock to a Dell laptop through TB bus, open the gnome-control-center and select the sound, we can see the USB headphone and USB Lineout from output device tab and USB Mic from input device tab. And both USB output and input work well.

Then change verification-needed-bionic to verification-done-bionic

Can we get this verified for cosmic as well?

...ignore me, I see the alsa-lib part has been already released for cosmic.
