@RanderWang

It's probably a mismatch between topology names and UCM expectations. @RanderWang @ranj063 FYI.

wait for thesofproject/sof#6508

@syedk008

@syedk008 Can you please clarify what HD-Audio codec(s) are you using on your MTL platform? Are you using the onboard ALC711 or external HD-Audio codec(s) on Realtek Add-in-card?

I can reproduce this issue on our MTL-RVP-HDA, I also copied the ucm2 files(https://github.com/thesofproject/alsa-ucm-conf/tree/master/ucm2/sof-hda-dsp) to /usr/share/alsa/ucm2/, but it still doesn't work.

ALC245 with Realtek Gen3.x card.

try using alsaucm to see what you are missing, it'll be a lot less complicated than figuring out what PulseAudio does. PulseAudio is history btw, you ought to be looking at PipeWire.

with changing PCM numbers for Dmic and HDMI in UCM files (Hdmi.conf and HiFi.conf), PulseAudio seems working. These changes may not be compatible with other platforms.

@ranj063

can you share those UCM changes, it means the topology is incorrect. @ranj063 @bardliao FYI

@ranj063 can you look into this?

@ranj063

I think the HDMI PCM IDs are wrong in cavs-passthrough-hdmi.conf

@ranj063 @bardliao any idea why we are using these, instead of default 5,6,7?
Define {
	NUM_HDMIS 	3
	HDMI1_ID	1
	HDMI2_ID	2
	HDMI3_ID	3
}

This seems to be redundant. We define HDMI_IDs in hdmi-default.conf

        HDMI1_ID                        5
        HDMI2_ID                        6
        HDMI3_ID                        7
        HDMI4_ID                        8

        HDMI4_ID                        8

But UCM expected ids are 3,4,5

That's right, the file ucm2/Intel/sof-hda-dsp/Hdmi.conf refers to HDMI devices 3,4,5

edit: makes sense, HDA analog is 0, digital 1 and alt digital 2. So the base can only be 3.

@plbossart

@plbossart In fact, HDMI1_ID is BE id, not PCM id. The pcm id is hard code to 5, 6, 7, 8.

hdmi-generic.conf will be used by sdw topologies, too. So, we can't simply update the pcm id.
See thesofproject/sof#6787

@syedk008

@syedk008 Could you please try thesofproject/sof#6904

@syedk008

@syedk008 Could you please try thesofproject/sof#6904

yes, changing DMIC_PCM_ID to 6 works. I had tested this change before.

@syedk008

@syedk008 Patches are merged. Could you please try the tplg for the latest sof code?

@syedk008

Closing. @syedk008 Please reopen this issue or file a new one if you still see opens.
