Make digital mic on the AMD Renoir machines work under gnome desktop

[Hui Wang]

[Impact]
On the LENOVO AMD Renoir machines, there is a digital mic directly
connected to the APU instead of the codec, so there are two separate
sound cards in the system, one is for analogue codec driven by hda
driver, the other is for the dmic driven by ASoC acp driver.

The current audio stack (pulseaudio + alsa-ucm-conf + alsa-lib) doesn't
support this design yet, it could support all audio devices on the codec
well, but it doesn't support that dmic well. In the gnome-control-center,
the dmic becomes two input devices: analog input and multichannel input,
and users can only record sound from analog input, the multichannel input
can't function at all. Besides this issue, there is another issue, after
users plug an external mic, the external mic can't replace the dmic
automatically, this gives users a bad experience since this behaviour is
different from the other audio designs.

[Test Case]
On the AMD Renoir machines:
* Boot the system with these updated packages (already backported kernel
drivers to Focal and oem-5.6 kernels), open the gnome-control-center
 - we could see the digital mic in the input device tab, and only one
input device
 - we could record sound through this dmic
 - we could play sound through the speaker
 - plug a headset, we could see the output device become headphones and the input device become headset mic
   - we could play sound to headphone and record sound from headset mic
 - plug an HDMI monitor, there is HDMI audio choice
   - play sound to HDMI audio, we could hear the sound from the speaker on the monitor
 - Suspend and resume, redo the previous steps, all audio devices still work well.

On other machines:
Boot the system with all updated packages or partial updated packages,
check all input devices and output devices, they worked the same as
before. this SRU doesn't bring any impact on other machines.

[Regression Risk]
For machines without using ucm, like traditional PC and Laptops with
HDA audio, it is possible that the pulseaudio can't parse the audio
devices well that there is only a dummy audio device on the
gnome-control-center, but the possibility is very low since this SRU
didn't touch the non-ucm part, and we already tested on a Dell HDA
audio machine, the audio function worked as well as before.

For machines using ucm, the regression possibility is the pulseaudio
fails to parse the needed ucm, then there is no dmic or there is only
a dummy audio device in the gnome-contro-center. This possibility is
very low too, We have tested this SRU on Dell and Lenovo dmic machines,
they worked as well as before. And for the LENOVO dual codec machine,
we don't have the hw at the moment, but changes for this machine are
all coming from upstream, and Cert team will verify the -proposed on
this machine since they have the machine. For other ucm machines, the
regression possibility is very low since this SRU doesn't touch their
ucm at all.

This SRU doesn't introduce any external API changes

[Sebastien Bacher (seb128)]

@Hui, thanks for the work. That's going to be a complicated SRU, just a small comment, the 'regression potential' section is supposed to describe what sort of problem could happen following the change, it's meant to give an hint of what to focus on in the testing

see https://wiki.ubuntu.com/StableReleaseUpdates#SRU_Bug_Template for detailed explanations

'low' (and the rest of the section focussing on why it's low) is sort of missing the point, could you rework it? I expect in that case we would need to test also on non AMD config that they are not regressing?

[Hui Wang (hui.wang)]

@Seb,

Ok, we are going to do the large scale test for this SRU, and after the test, I will rewrite the [Regression Risk].

Once the debdiff is uploaded, it is ready to review.

thx.

[Hui Wang (hui.wang)]

@seb,

I plan to upload the debdiff for focal, but how to handle the groovy? we will definitely upgrade those packages to higher version in the groovy sooner or later, do I need to upload debdiff for groovy as well?

[Sebastien Bacher (seb128)]

@Hui, we will get the new version but unsure when so if it's not too much extra work it would be b etter to generate debdiffs for G

[Hui Wang (hui.wang)]

OK, got it, will upload for G.
thx.

[Hui Wang (hui.wang)]

This is the alsa-lib debdiff for Groovy.

thx.

[Hui Wang (hui.wang)]

This is alsa-ucm-conf debdiff for Groovy.

thx.

[Hui Wang (hui.wang)]

This is the pulseaudio debdiff for Groovy.

thx.

[Hui Wang (hui.wang)]

This is alsa-lib debdiff for Focal.

thx.

[Hui Wang (hui.wang)]

This is alsa-ucm-conf debdiff for Focal.

thx.

[Hui Wang (hui.wang)]

This is pulseaudio debdiff for Focal.

thx.

[Sebastien Bacher (seb128)]

Thanks, I've uploaded the changes to groovy now. It would be nice having some confirmation it works there before SRUing to focal. One point for improvement also, the changelog have no human description of the changes which is suboptimal, especially in case of a SRU

[Sebastien Bacher (seb128)]

I've also commited to the pulseaudio Vcs, the alsa packages don't have a Vcs

[Hui Wang (hui.wang)]

Thanks Seb.

And I verified that these 3 groovy packages worked very well on 4 machines I have.

Install the groovy daily built image on the lenovo amd renoir laptop, enable the -proposed, install the pulseaudio_13.99.1-1ubuntu9, alsa-lib_1.2.2-2.3ubuntu2 and alsa-ucm-conf_1.2.2-1ubuntu2, reboot. open the gnome-sound-setting, there is digital mic in the input device list, and It could record the sound. run suspend and resume, recheck the digital mic, it still could record the sound. check speaker and hdmi audio, all worked as before, plug a headset, sound could output to headphone and I could use headset-mic to record the sound too.

Then I did the same test on a Dell dmic machine, a lenovo I+N hda audio machine and a dell intel hda audio machine, the audio all worked as well as before. Didn't find any regression on the new packages.

thx.
