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

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:

Takashi
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 ?

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 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).

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

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.
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).
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.
thanks,
