@rodrigovivi if you have 2 DMICs and no HDaudio external codec, then chances are the configuration is similar to the HP SoundWire versions.

Can you add this file sof-dyndbg.conf.txt as /etc/modprobe.d/sof-dyndbg.conf, reboot then attach the dmesg log.

Also provide the result of

cat /sys/bus/acpi/devices/*/adr  | grep 025d

[rodrigovivi]

$ cat /sys/bus/acpi/devices/*/adr | grep 025d 0x000030025d071201

[plbossart]

Thanks @rodrigovivi, so you have one RT712 on SoundWire link0, 2 DMICs and HDMI support with iDISP.

of course we don't support this configuration...

Usually we have a RT712 for jack/amp and the RT1712 for the DMIC. Here the latter seems replaced by the PCH-attached DMIC.

wow. I'll start cooking up a patch shortly.

[plbossart]

@rodrigovivi can you try the patch in PR thesofproject/sof#4925 and also unzip/copy this file sof-mtl-rt712-l0-2ch.tplg.gz in /lib/firmware/intel/sof-ipc4-tplg/

Reboot and attach the results. You should see a sound card if I didn't screw up the indices.

Thanks!

[rodrigovivi]

dmesg-audio-with-patch-take-1.txt It goes further, then it fails...

[plbossart]

Ok that's probably the topology file, I don't really understand how the indices are handled. @bardliao can you take a look?

[rodrigovivi]

one important information here: the sound over USB works pretty well even without this patch. USB speaker and USB headset works well. only the native laptop speakers and mic doesn't work. I was surprised by that over the weekend. So, I really can do meetings on this laptop and sound works for my regular case. But I'm still up to test any patch here and get this product really working out of the box. There might be users out there who really depend on the native speakers/mic.

[bardliao]

@rodrigovivi Can you try sof-mtl-rt712-l0-2ch.zip?

The dmic01 id is 3. I modified the indices in the topology.

[plbossart]

The dmic01 id is 3. I modified the indices in the topology.

@bardliao is this because we don't have the amp feedback on rt712?

Yes, BT and USB are orthogonal to the Intel IP for audio, so they might work even if the DSP doesn't. Still there's no reason why this configuration wouldn't work with minor tweaks, as you said there will be lots of others who need jack/speaker/mic.

[bardliao]

The dmic01 id is 3. I modified the indices in the topology.

Yes.

@rodrigovivi Thanks for testing. Could you try sof-mtl-rt712-l0-2ch.zip?

[bardliao]

@rodrigovivi Do you have a chance to test sof-mtl-rt712-l0-2ch.zip? We will merge https://github.com/thesofproject/sof/pull/9041 if the test result is positive.

Hello everyone! I'm also having this issue in a Swift SFG14-72 running latest Ubuntu 24.04. I tried the linked topology and it didn't work for me. Is this ticket going to be continued in issue 9085? Is there something I can help to debug this?

@franc5 You need to apply https://github.com/thesofproject/linux/pull/4925 to your kernel. And from https://github.com/thesofproject/linux/issues/4970, https://github.com/thesofproject/sof/pull/9041 should be good. The DSP panic looks like a different issue.

[rodrigovivi]

I'm sorry for the late reply here. With the latest sof-mtl-rt712-l0-2ch.zip I do can see the output audio enumerated, but no sound is audible when testing the speakers. also no microfone enumerated. dmesg-apr-29.txt

[plbossart]

@rodrigovivi I don't know what's going on with GitHub but your attached dmesg-apr-29 didn't go through.

[rodrigovivi]

dmesg-apr-29.txt

[plbossart]

@rodrigovivi I don't see anything wrong in the dmesg log. The speakers probably miss a mixer config. For the dmics, I don't really understand what you meant by "no microphone enumerated". what is the output of 'arecord -l' ?

[rodrigovivi]

The Gnome Settings shows the output device, but even with tuning the volume, nothing is audible. But for the input devices it just shows: "No Input device"

$ arecord -l List of CAPTURE Hardware Devices card 1: sofsoundwire [sof-soundwire], device 1: Jack In () [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: sofsoundwire [sof-soundwire], device 10: DMIC Raw () [] Subdevices: 1/1 Subdevice #0: subdevice #0

[plbossart]

that's because you don't have a UCM file.

Try capturing something with "arecord -Dhw:0,10 -c2 -r48000 -fS32_LE -d10 test.wav" and see if there's any sound coming in.

[rodrigovivi]

I couldn't hear anything... then I plugged the usb-audio, where I can hear stuff and I played it again and still couldn't hear anything. so, still output is listed, but it doesn't work. input is not listed and even arecord directly didn't worked.

[plbossart]

"arecord directly didn't work" Did you mean that the recorded file is silent, or that some sort of error happened. It could be that we are using the 'wrong' set of channels, the interface supports 4 channels so if the OEM picks 2 we have a chance on using the pdm1 instead of classic pdm0.

[rodrigovivi]

silent! I couldn't listen to anything...

[plbossart]

ok, so we need to try the 4ch setup and see if the channels 2-3 are used

Can you add this in a .conf file in /etc/modprobe.d/

options snd_sof_intel_hda_common dmic_num=4

and unzip/add this topology file sof-mtl-rt712-l0-4ch.tplg.gz

if you can record something and share the wav file that would be great.

[plbossart]

Oh and the number of channels needs to change of course:

arecord -Dhw:0,10 -c4 -r48000 -fS32_LE -d10 test.wav

[rodrigovivi]

$ find /lib/firmware/intel/sof-ipc4-tplg/ | grep sof-mtl-rt712-l0-4ch /lib/firmware/intel/sof-ipc4-tplg/sof-mtl-rt712-l0-4ch.tplg

dmesg-apr-30.txt

[plbossart]

Not following what goes sideways, we do add the 4ch count

"cavs-sdw\;sof-mtl-rt712-l0-4ch\;PLATFORM=mtl,NUM_SDW_AMP_LINKS=1,\
SDW_AMP_FEEDBACK=false,SDW_SPK_STREAM=Playback-SmartAmp,\

NUM_DMICS=4,PDM1_MIC_A_ENABLE=1,PDM1_MIC_B_ENABLE=1,DMIC0_ID=3,DMIC1_ID=4,\
PREPROCESS_PLUGINS=nhlt,NHLT_BIN=nhlt-sof-mtl-rt712-l0-4ch.bin,\
HDMI1_ID=5,HDMI2_ID=6,HDMI3_ID=7"

It's possible though that somehow we use the NHLT blob coming from ACPI tables.

But at the same time, I see

[  483.498873] snd_sof:sof_ipc4_prepare_copier_module: sof-audio-pci-intel-mtl 0000:00:1f.3: copier host-copier.10.capture: reference output rate 48000, channels 2

so not sure what's going on. @bardliao @ranj063 any ideas?

[bardliao]

Maybe try "options snd_sof_intel_hda_common sof_use_tplg_nhlt=1" to use the nhlt in the topology first?

[rodrigovivi]

options snd_sof_intel_hda_common sof_use_tplg_nhlt=1 and options snd_sof_intel_hda_common dmic_num=4 ?

[plbossart]

yes both options @rodrigovivi

[rodrigovivi]

Using both: $ cat /proc/cmdline [snip] snd_sof_intel_hda_common.sof_use_tplg_nhlt=1 snd_sof_intel_hda_common.dmic_num=4

dmesg-may13.txt

$ arecord -Dhw:0,10 -c4 -r48000 -fS32_LE -d10 test-4ch-may-13.wav arecord: set_params:1398: Channels count non available

mic still not listed in the gnome sound configuration.

[plbossart]

for some reason, even with the 4ch option the kernel selects the 2ch topology

[   15.253637] sof-audio-pci-intel-mtl 0000:00:1f.3: DMICs detected in NHLT tables: 2

Not sure why that is the case.

My money is on the option not being selected, if you enable dynamic debug you should see this, but it's not in your log...

/* allow for module parameter override */
    if (dmic_num_override != -1) {
        dev_dbg(sdev->dev,
            "overriding DMICs detected in NHLT tables %d by kernel param %d\n",
            dmic_num, dmic_num_override);
        dmic_num = dmic_num_override;
    }

[rodrigovivi]

what debug config and/or levels do you need? But what to do to allow the override and not end up in this place.

[plbossart]

just make sure the sof-dyndbg.conf file exists in /etc/modprobe.d/ as described earlier in https://github.com/thesofproject/linux/issues/4923#issuecomment-2052436089

[plbossart]

@marplusz see https://github.com/thesofproject/linux/issues/4923#issuecomment-2054591643

I am not sure what the status is, we never had any test results on the files suggested in https://github.com/thesofproject/sof/pull/9041 and there are comments from @ujfalusi that were not addressed either.

Bottom line we need to reopen this for the 2ch case.

[bardliao]

@marplusz @rodrigovivi @plbossart The dmic_num=4 belongs to the snd_sof_intel_hda_generic module not snd_sof_intel_hda_common. So, the options should be

options snd_sof_intel_hda_common sof_use_tplg_nhlt=1 options snd_sof_intel_hda_generic dmic_num=4

And the tplg file will be sof-mtl-rt712-l0-4ch.tplg

I set the options: options snd_sof_intel_hda_common sof_use_tplg_nhlt=1 options snd_sof_intel_hda_generic dmic_num=4

I recorded a wav file: arecord -Dhw:0,10 -c4 -r48000 -fS32_LE -d10 test.wav

No sound was recorded. I checked the file in Audacity and nothing was recorded on any channel.

@marplusz can you add this file sof-dyndbg.conf.txt as /etc/modprobe.d/sof-dyndbg.conf, reboot and attach the dmesg log. Thanks!

Log file from dmesg dmesg_log.txt

[plbossart]

the log is missing all the initial parts that can help us see what the configuration is @marplusz

[marplusz]

@plbossart Please write what I should insert. Above I made the usual ones dmesg > dmesg_log.txt

[marplusz]

I updated the system and did it again. I can see the difference in the log. I have a vanilla kernel so it may be unstable. dmesg_log2.txt

@marplusz Can you share the output of "amixer contents" command while you are running the arecord command?

[marplusz]

@bardliao To do this, I restored the parameters: options snd_sof_intel_hda_common sof_use_tplg_nhlt=1 options snd_sof_intel_hda_generic dmic_num=4 I rebooted journalctl | grep audio -> journalctl.txt dmesg -> dmesg_log

_terminal1 -> arecord -Dhw:0,10 -c4 -r48000 -fS32_LE -d10 test.wav

_terminal2 -> amixer contents numid=4,iface=MIXER,name='Master Playback Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on numid=3,iface=MIXER,name='Master Playback Volume' ; type=INTEGER,access=rw------,values=2,min=0,max=655

36,step=1 : values=45212,45212 numid=2,iface=MIXER,name='Capture Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on numid=1,iface=MIXER,name='Capture Volume' ; type=INTEGER,access=rw------,values=2,min=0,max=65536,step=1 : values=45212,45212 journalctl.txt dmesg_log.txt

@marplusz Sorry, you need to specify the card number. Please redo this with amixer -c0 contents.
