[BUG] No sound on Acer Swift SFG14-72-735T (Intel Ultra 7 155H)

[liquidev]

There seems to be missing firmware for the DSP chip used in this particular laptop. Journalctl mentions a missing topology file:

I've looked for this topology file but it doesn't seem to exist anywhere. There's only sof-tplg/sof-hda-generic-idisp-2ch.tplg, but not sof-ace-tplg/sof-hda-generic-idisp-2ch.tplg.

The following audio chip is reported in lspci:

@liquidev can you try installing v2.9 https://github.com/thesofproject/sof-bin/releases/tag/v2024.03

[liquidev]

@lgirdwood I did try installing the latest release there before submitting this issue but to no avail. (Tried uninstalling the Arch-provided package and then using install.sh from the tarball, the effect was the same.)

I believe the Arch-provided package may simply be the same as the v2024.03 tag in sof-bin. Unless you're saying I should try cloning the repo and installing from there instead of using the tarball.

[liquidev]

Just tried installing v2.9 from the git cloned repo, no luck either. Same systemd journal logs as before.

[lgirdwood]

I've looked for this topology file but it doesn't seem to exist anywhere. There's only sof-tplg/sof-hda-generic-idisp-2ch.tplg, but not sof-ace-tplg/sof-hda-generic-idisp-2ch.tplg.

Can you try a soft link here so the kernel will find a similar file.

@ujfalusi @plbossart fyi - could the arch kernel be missing a kernel patch ?

[ujfalusi]

It is a SDW device:

Apr 26 11:28:17 construct kernel: sof-audio-pci-intel-mtl 0000:00:1f.3: DSP detected with PCI class/subclass/prog-if info 0x040100
Apr 26 11:28:17 construct kernel: sof-audio-pci-intel-mtl 0000:00:1f.3: SoundWire enabled on CannonLake+ platform, using SOF driver
..
Apr 26 11:28:17 construct kernel: sof-audio-pci-intel-mtl 0000:00:1f.3: No SoundWire machine driver found
Apr 26 11:28:17 construct kernel: sof-audio-pci-intel-mtl 0000:00:1f.3: hda codecs found, mask 4

Apr 26 11:28:17 construct kernel: sof-audio-pci-intel-mtl 0000:00:1f.3: DMICs detected in NHLT tables: 2

Since no SDW machine driver was found the stack falls back to HDMI only topology, but indeed we only have the basic sof-hda-generic-idisp.tplg which does not support DMIC (and this machine has SDW+DMIC+HDMI).

The root cause is that we don't know this setup, so we fail to get the correct machine driver and the fallback to HDMI+DMIC does not work due to missing tplg.

@kv2019i, FYI

Is there anything I can do to fix this (or help fix this?)

@lgirdwood I tried making the symlink but it's failing with a different error now:

[ujfalusi]

@liquidev, can this help you: #4923

[liquidev]

@ujfalusi It looks promising but I have no idea where to begin testing out the patches. Do I need to compile the thesofproject/linux kernel with the patches, and then put the tplg file wherever the kernel module will tell me to? Or does this only involve recompiling the sof-specific kernel modules and then installing them somehow?

Any pointers or instructions would be appreciated 😄

[plbossart]

Can you attach the results of this updated script (bash alsa-info.sh.txt), i'll help us check if this is really a SoundWire topology.

alsa-info.sh.txt

[liquidev]

Sure, here it is:

alsa-info.txt

I'll get to setting up a local kernel for testing in the meantime.

[liquidev]

I'm afraid I can't set up a custom kernel by myself, it's beyond my technical ability at the moment. After a couple hours I managed to compile it successfully but then Arch's mkinitcpio fails to produce me a usable initramfs, which causes my root partition to not be loaded properly.

I just want my audio to work 😕

Operating System: Windows 11

I'm afraid I can't set up a custom kernel by myself, it's beyond my technical ability at the moment.

The only way not to have to go through all this pain is to buy a device that officially supports Linux. This is especially true with audio where there is a lot of hardware "creativity".

I hope you can find someone who can help you with this sort of kernel hacking.
