[ALSA] [PATCH] Clevo P950ER ALC1220 Fixup

[Jeremy Soller]

== SRU Justification ==
This request is to add a sound quirk requested by System76. This adds
support for the P950ER, which has the same required fixup as the P950HR,
but has a different PCI ID.

The patch was already submitted upstream in this email:
http://mailman.alsa-project.org/pipermail/alsa-devel/2018-May/135685.html

However, the patch has not landed in mainline as of yet, so it is being
requested as SAUCE.

== Fix ==
UBUNTU: SAUCE: ALSA: hda/realtek - Clevo P950ER ALC1220 Fixup

== Regression Potential ==
Low. Limited to a new sound quirk.

== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.

I built a Bionic test kernel with your patch.

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1760721

Can you test this kernel and see if it resolves this bug?

Note about installing test kernels:
• If the test kernel is prior to 4.15(Bionic) you need to install the linux-image and linux-image-extra .deb packages.
• If the test kernel is 4.15(Bionic) or newer, you need to install the linux-image-unsigned, linux-modules and linux-modules-extra .deb packages.

Thanks in advance!

Thanks, I am looking at it now.

[Jeremy Soller (jackpot51)]

The audio, which does not work with the current Ubuntu kernel, now works as expected!

[Jeremy Soller (jackpot51)]

By the way, I installed the kernel from http://kernel.ubuntu.com/~jsalisbury/lp1769721/, since the above link had a 0 instead of a 9.

[Joseph Salisbury (jsalisbury)]

Thanks for testing and sorry for the typo. I'll submit and SRU request for this patch.

[Jeremy Soller (jackpot51)]

Thanks, I appreciate the help in getting it into Ubuntu!

Hello jsalisbury,

I am wondering what the process is for merging this now that the SRU was acked.

Thanks

[Joseph Salisbury (jsalisbury)]

We need two acks and then commit will be applied to the master-next kernel source branch. It will then be released to the -proposed repo before it goes to -updates.

There is a wiki that describes the process here:
https://wiki.ubuntu.com/KernelTeam/KernelUpdates

[Jeremy Soller (jackpot51)]

Thanks for the information!

[Brad Figg (brad-figg)]

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!

[Jeremy Soller (jackpot51)]

I do not see the linux-image-4.15.0-23-generic package in proposed

[Jeremy Soller (jackpot51)]

I finally saw all the packages in proposed - I guess they are not published at the same time?

I am testing now.

[Jeremy Soller (jackpot51)]

Brad, the 4.15.0-23 kernel solves the problem.
