alsa-project alsa-ucm : Audio endpoint is not switching when external mic connected

alsa-project alsa-ucm : Audio endpoint is not switching when external mic connected

[Mukunda, Vijendar]

We recently up streamed ACP PDM driver for Renoir APU.

Our ACP IP has an internal PDM Decoder block where DMIC is directly connected.
There are no KControls defined for PDM Driver.

Our platform supports on board DMIC and South bridge Azalia (HD Audio ) endpoint .
By default, DMIC endpoint is used as audio input device.
When Headset Mic jack connected, it's not switching to External Mic.

How does audio endpoint will switch in gnome when external mic is connected?
From our understanding, UCM conf file for HDA driver is also required for 
configuring mixer controls for HD Audio capture device.
Similarly when External Mic is removed , it has to switch to internal dmic .

Need help in resolving this issue.

Thanks,
Vijendar

Make sure that the Headset Mic priority port in pulseaudio is is greater than 
the one for DMIC.

An configuration example for UCM (DMIC connected to DSP, HDA codec for rest):

   https://github.com/alsa-project/alsa-ucm-conf/tree/master/ucm2/sof-hda-dsp

If you need a help to create a new configuration for your hardware, show the 
output from the alsa-info.sh script, please.

This audio design is  a bit different from sof-hda-dsp, the dmic is on a 
standalone sound card. Please see the alsa-info.txt:

And that's an interesting case.  Can we manage multiple cards in a
single UCM profile?

I am not much familiar with UCM files creation.
As per my understanding, UCM entries will program the mixer controls
depending up on the use case and selected device.

But for PDM sound card there are no mixer controls defined.
Do we still need to add UCM entries for PDM sound card  along with UCM entries for
HD Audio sound card ?
For example mentioning the pcm device for PDM sound card, 
even we don't program any specific kcontrols ?

UCM is more than that.  It manages which PCM device is chosen, which
jack control corresponds, etc, too.

Got it. Could you help us to get the UCM file which will work for both sound cards for our platform.

UCM describes the verbs (profiles), devices (ports in PA) in verbs and the 
enable/disable/transition settings. So it's not only about the kcontrols.

Basically, for your case, you need to configure pulseaudio correctly for the 
legacy probe ALSA soundcard mechanism (priorities). PA should switch to the 
profile/port with the highest priority when available. There is also some 
gnome code which handles the shared mic/headset mic inputs where the hardware 
cannot detect the connected device (it may not work for your case correctly).

Or, you may create one UCM verb with the devices from multiple ALSA soundcards 
(and the PA will handle this in the one profile like one legacy soundcard).

Yes, it should work, but we need to extend pulseaudio to avoid fallback to the 
legacy ALSA profile when the "slave" soundcard is enumerated. PA should skip 
this card. We need to check if the empty UCM verb is supported.

Also, UCM has ${CardId} substitution (for the master card config), but we need 
to address the slave, too. Perhaps, we should add something like 
${GetCardIdByName:STRING[:INDEX]} where STRING may be the name of the 
soundcard (it will be 'acp') in this case. The INDEX may refer to multiple 
instances (INDEX = 0 first soundcard found).

I suppose it's not only about PA, but in general we need to define how
to deal with it.  I can imagine to provide a UCM profile that is
mapped to some dummy ops for the slave card, for example.

FWIW, I see a similar requirement for the recent change in USB-audio
for Gigabyte Auros Master with AMD TRX40: it provides a front
headphone output from a separate card while other I/Os are served by
another card.  It'd be handy if both can be combined.

Please, create a new issue with the mentioned alsa-info URL at github:

https://github.com/alsa-project/alsa-ucm-conf/issues

I'll give a look when my time permits.
