Audio driver fails to load on Meteor Lake reference board

[JianpengChang]

Hello,

I'm doing some tests on the MTL RVP, there is something wrong with the firmware of sof, the error is missing sof-mtl-rt711-2ch.tplg. But there is no sof-mtl-rt711-2ch.tplg in any version of sof-bin.
I have tried the latest Linux kernel, and got the same error. But if I rename the sof-mtl-rt711-4ch.tplg which I can see in the latest version v2025.1 of sof-bin to sof-mtl-rt711-2ch.tplg, it works. I have read the similar issue #4880, so is this a similar error that the RVP configuration is wrong makes it point to 2ch.tplg?. Hopefully to get any guidance.

Environment:

• MTL-P DDR5 SODIMM SBS RVP
• Intel(R) Core(TM) Ultra 7 155H
• linux 6.6.78-yocto-standard

@bardliao are we missing a 2ch dmic topology variant in sof-bin?

[bardliao]

@JianpengChang Can you try sof-mtl-rt711-2ch.zip?
The PR is thesofproject/sof#9910

[JianpengChang]

@bardliao, it work on the latest kernel 6.14

@JianpengChang Can you renamesof-dyndbg.conf.txt to sof-dyndbg.conf and put it in the /etc/modprobe.d/ folder and share the full dmesg log? It looks like you need to update your display driver. But I don't know is there other error in the dmesg.

May I know why you need to use the 6.6.78 kernel?

[bardliao]

@JianpengChang Can you check if DMIC capture work well?

[ranj063]

@bardliao, it work on the latest kernel 6.14

The new topologies wont work with the older kernel because we use partial matching for the stream names.

@JianpengChang Can you renamesof-dyndbg.conf.txt to sof-dyndbg.conf and put it in the /etc/modprobe.d/ folder and share the full dmesg log? It looks like you need to update your display driver. But I don't know is there other error in the dmesg.

May I know why you need to use the 6.6.78 kernel?

alsa-info.txt
dmesg.txt

It's the strategy of Yocto. They are maintaining different versions of kernel, base on the upstream to do some backports and fixes. Usually we don't use the latest kernel.
It's not inconvenient for me to check DMIC today, really sorry.

[JianpengChang]

@bardliao, it work on the latest kernel 6.14

But, it doesn't work on 6.6.78, it seems that I need fetch some patches. Here is the error log:

The new topologies wont work with the older kernel because we use partial matching for the stream names.

Do we have a plan to support older version? If not, this means we have to update kernel or backport, if a tplg is missing again, am right?

Really thanks for your replay. @ranj063 @bardliao

[bardliao]

Not sure if you put sof-dyndbg.conf.txt to the /etc/modprobe.d/ folder properly. It seems there is no required debug log in your dmesg.
I removed the iDisp devices from the topology. sof-mtl-rt711-2ch-noHDMI.zip Hope it help.

[JianpengChang]

It works but the HDMI codec still failed.
