Support for Realtek audio solution ALC3329B+ALC1708B on new Dell PTL platform

[Chris Chiu]

SRU Justification:

[Impact]
New Dell platform with Realtek codec ALC3329B+ALC1708B powered by Intel PantherLake will have no basic audio functions w/o Soundwire Driver Support.

================ Linux Kernel ========================

[Fix]
Backport new Intel soundwire drivers of the following
ASoC: sof-function-topology-lib: escalate the log when missing function topoplogy - kernel/git/broonie/sound.git - ASoC
ASoC: SOF: Intel: use sof_sdw as default SDW machine driver - kernel/git/broonie/sound.git - ASoC
ASoC: SOF: add platform name into sof_intel_dsp_desc - kernel/git/broonie/sound.git - ASoC
ASoC: soc_sdw_utils: export asoc_sdw_get_dai_type - kernel/git/broonie/sound.git - ASoC
ASoC: Intel: export sof_sdw_get_tplg_files - kernel/git/broonie/sound.git - ASoC
ASoC: soc_sdw_utils: add name_prefix to asoc_sdw_codec_info struct - kernel/git/broonie/sound.git - ASoC
ASoC: soc-acpi: make some variables of acpi adr and link adr non-const - kernel/git/broonie/sound.git - ASoC
ASoC: SOF: Don't print the monolithic topology name if function topology may be used - kernel/git/broonie/sound.git - ASoC
ASoC: SOF: don't check the existence of dummy topology - kernel/git/broonie/sound.git - ASoC

and ALC3329B+ALC1708B from Realtek

ASoC: rt722: add settings for rt722VB - kernel/git/broonie/sound.git - ASoC
ASoC: rt1321: Add RT1321 amplifier support - kernel/git/broonie/sound.git - ASoC
ASoC: rt712: avoid skipping the blind write - kernel/git/broonie/sound.git - ASoC
ASoC: sdw_utils: add rt1321 part id to codec_info_list - Patchwork
ASoC: sdw_utils: add name_prefix for rt1321 part id - kernel/git/broonie/sound.git - ASoC
ASoC: SOF: Intel: add hyphen between name and index to amp name_prefix - kernel/git/broonie/sound.git
ASoC: SOF: don't check the existence of dummy topology - kernel/git/broonie/sound.git - ASoC

=============== linux-firmware ========================

[Fix]
Backport the patch firmware from Realtek
realtek: rt1321: Add patch firmware of MCU - kernel/git/firmware/linux-firmware.git - Repository of firmware blobs for use with the Linux kernel

=============== alsa-ucm-conf ========================

[Fix]
Backport the patch

and

PR (https://github.com/alsa-project/alsa-ucm-conf/pull/628 [github.com])

 from upstream

[Test Case]
1. Boot up the machine of new Dell Intel PantherLake platform with Realtek ALC3329B+ALC1708B.
2. Open settings->Sound->Output Device and make sure it's not Dummy audio devices
3. Click test icon for basic audio output functions
4. Use `arecord` to record and play the recorded audio file with `aplay` for basic speaker/microphone functions.

[Where problems could occur]
It adds the support for new Realtek codec+amplifier on PTL platform. No regression expected at the current stage.

This bug is awaiting verification that the linux-oem-6.17/6.17.0-1007.7 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-noble-linux-oem-6.17' to 'verification-done-noble-linux-oem-6.17'. If the problem still exists, change the tag 'verification-needed-noble-linux-oem-6.17' to 'verification-failed-noble-linux-oem-6.17'.

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.

what about the resolute kernel?

[Timo Aaltonen (tjaalton)]

Hello Chris, or anyone else affected,

Accepted linux-firmware into noble-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/linux-firmware/20240318.git3b128b60-0ubuntu2.22 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, what testing has been performed on the package and change the tag from verification-needed-noble to verification-done-noble. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-noble. 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.

[Nick Rosbrook (enr0n)]

I sponsored the resolute upload with one minor change -- you forgot to run `update-maintainer`, which ensures that the Maintainer field in debian/control is set correctly for Ubuntu.

[Nick Rosbrook (enr0n)]

The questing debdiff is very difficult to review. There is a lot going on there.

Two of the bugs referenced are marked fixed released. What's going on there?

There appear to be about 20 patches added, yet it's very unclear which patches apply to which bug. This is difficult to review.

Please, consider (a) re-submitting as a git-ubuntu PR so that individual commits can be associated with the appropriate patches, (b) use debian/patches/lpXXXXXXX subdirs to organize patches by bug, and (c) use proper DEP3 patch headers like Bug-Ubuntu to indicate the relevant bug there, too.

Hi @enr0n,

The initial version of the patch was uploaded 1.2.12-1ubuntu2 under lp:2100732,
but the fix(lp:2106394) was revised twice afterwards. Unfortunately, we missed carrying the final/revised fixes forward.

The verification of the Stable Release Update for linux-firmware has completed successfully and the package is now being 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 Nick,

May I know if it is ok to upload noble before @binli fix questing's problem?

Thanks,

[Viral Wang (viralwang)]

Hi @enr0n,

Apologies for jumping in at this point.

As the project manager for the PC program, I would like to share some considerations regarding the business impact of the customers' Panther Lake platforms. Based on this assessment, we may sincerely appreciate your kind support in prioritizing the Noble upload.

Please kindly let me know if there is anything I can assist with or any additional information required from my side to help facilitate or expedite the process.

Thank you very much for your support and understanding.

[Bin Li (binli)]

Hi @enr0n,

 Thanks for your feedback, I have updated the changelog to make it simpler.

[Nick Rosbrook (enr0n)]

The noble upload is blocked by the questing upload. So no, it cannot proceed before questing. I have not even had a chance to review the noble debdiff yet due to the questing reviews.

Thanks for the new debdiff. I will review again soon.

[Nick Rosbrook (enr0n)]

Thanks for making the changelog simpler. I think it's more clear what is actually being changed now. I have sponsored questing.

[Nick Rosbrook (enr0n)]

The noble changes look good to me, but Michael Lin asked me about including another change (bug 2131725) in the noble SRU, so I am getting mixed messages about prioritization here.

I am waiting to upload noble until things are clarified.

[Nick Rosbrook (enr0n)]

Sponsored noble now as well.
