[HELP NEEDED] Legion Pro 7 16IAX10H - Missing ALC287+AW88399 topology and quirks
Hi SOF developers,
I'm reaching out for help getting audio working on the Lenovo Legion Pro 7 16IAX10H (subsystem ID 17aa:3906/17aa:3907). This laptop uses an Intel Arrow Lake-S platform with:
* Codec: Realtek ALC287 (detected as ALC287, actually ALC3306 per specs) * Amplifiers: Awinic AWDZ8399 (x2) on i2c-2 at 0x34 and 0x35 * ACPI device: _SB.PC02.I2C2.SPKR with device ID "AWDZ8399"
*Current Status:*
The good news is that the snd_soc_aw88399 codec driver exists (kernel 6.7+) and successfully binds to the I2C devices. When I force SOF with |snd_intel_dspcfg.dsp_driver=3|:
* sof-audio-pci-intel-mtl claims the device successfully * SOF firmware loads: intel/sof-ipc4/arl-s/sof-arl-s.ri (v2.13.0.1) * However, it falls back to the generic machine driver (skl_hda_dsp_generic) * This loads intel/sof-ace-tplg/sof-hda-generic.tplg * This topology only includes HDA codec paths - NO I2C amplifier integration
*The Problem:*
Without proper topology and machine driver integration, the AW88399 amplifiers aren't connected to the audio pipeline. Currently, audio is extremely quiet and tinny (sounds like only tweeters working?)
*What's Needed:*
1. A topology file for ALC287 + AW88399 combination (e.g., "sof-arl-alc287-aw88399.tplg") 2. ACPI/DMI quirk entries for 17aa:3906 and 17aa:3907 that: * Force SOF driver instead of legacy snd_hda_intel * Select appropriate machine driver (not generic) * Configure SSP routing for codec + I2C amplifiers
This might be distantly similar to existing implementations like sof-mtl-rt5682-max98357a.tplg.
*How I Can Help:*
I'm happy to:
* Test patches and provide detailed logs * Provide ACPI dumps or any other system information needed * Help with debugging and validation
This issue affects multiple recent Lenovo laptops with ALC3306 codecs (see kernel bugzilla |#219651|), so a fix would benefit many users.
We've already discussed this issue extensively here: https://bugzilla.kernel.org/show_bug.cgi?id=218329
There are also discussions here: https://forum.garudalinux.org/t/audio-issues-on-lenovo-legion-pro-7-16iax10h...
Any guidance or pointers would be greatly appreciated!
Thank you!

On HDA device the i2c codecs are usually connected to the HDA codec and they control them. I personally have not seen any device which would have Analog HDA codec and an i2s (SSP) codec connected directly to Intel SSP port.
Others can correct me on this..
I think what you need is something similar to other Legion devices where different amps have been used:
$ cat sound/hda/codecs/realtek/alc269.c | grep "Lenovo Legion 7" SND_PCI_QUIRK(0x17aa, 0x3877, "Lenovo Legion 7 Slim 16ARHA7", ALC287_FIXUP_CS35L41_I2C_2), SND_PCI_QUIRK(0x17aa, 0x3878, "Lenovo Legion 7 Slim 16ARHA7", ALC287_FIXUP_CS35L41_I2C_2),
Basically you need to figure out how the AWDZ8399s are connected and what commands they need. Only Lenovo or Realtek/Awinic might know what needs to be done to get the speakers working as they should.

Thank you very much for your answer!

I am essentially a just random Linux user. I don't have any connections into Lenovo, Realtek or Awinic. What can I do to help work on this issue? All I have is my laptop. I'm happy to provide any information I can about the hardware, to run tests, and to help with development, but I can't just randomly ask people at Lenovo or Realtek or Awinic what is needed to get the speakers to work, since I don't know anyone who works there. I'm just some guy.
I still want to help, even if that involves potentially contributing code. Just tell me what I can do!
Thank you,

I would send a mail to linux-sound@ver.kernel.org, Cc-ing Takashi Iwai tiwai@suse.de
and ask for help and hints on what to try.
Unfortunately we don't have information on these devices and their setups and since it is shipped Windows, OEMs are not too eager to help.
There are success stories of capturing HDA verbs from Windows and using those sequences in Linux then converting that to a patch, but I cannot help with that.
I still want to help, even if that involves potentially contributing code. Just tell me what I can do!
At this point I would start with linux-sound and see if you can get pointers from there to how to proceed.

Hi Péter,
Thank you, I just sent an email to linux-sound cc’ing Takashi Iwai as you recommended.
Regarding capturing HDA verbs from Windows, I’d be perfectly happy to try to do that and document what I get if it would help in creating a patch. I’ve never done this before (I only found out today what an “HDA verb” even is), so this might take some time. But I’ll see if I can get some kind of log that shows the HDA verbs used by the Windows driver, and share it online.
