Acer Aspire AV16-71P (Arrow Lake, ARL): No SoundWire machine driver found (RT712-only link 0 config, internal speakers/mic/headset jack missing) #5891
Description
Description
Internal speakers, headset jack and DMICs do not work on this laptop. Only HDMI outputs (from the Intel HDMI codec) are exposed by PipeWire/ALSA; Bluetooth audio works fine since it does not depend on the DSP.
The kernel reports No SoundWire machine driver found and falls back to skl_hda_dsp_generic with the HDMI-only topology, so the Realtek RT712 (jack/speaker/mic) on SoundWire link 0 is never instantiated.
This looks similar to #4923 (Swift Go 14, MTL), but on Arrow Lake, and with only the RT712 reported on link 0 — no separate amplifier codec is reported by ACPI.
I checked current upstream:
- commit 242200c ("ASoC: soc-acpi-intel-arl-match: add rt712_l0_rt1320_l3 support", in v7.1) adds an ARL entry for RT712-l0, but it requires an RT1320 on link 3 (
arl_rt712_l0_rt1320_l3) plus thesnd_soc_acpi_intel_sdca_is_device_rt712_vb()machine check. This machine reports no device on link 3. - The referenced topology
sof-arl-rt712-l0-rt1320-l3.tplgis not present in sof-bin (checked up to v2.14.3) either.
So this specific configuration (ARL + RT712 on link 0 only + PCH DMICs + iDISP HDMI) appears to be unsupported so far. Could a match entry + topology be added for it (analogous to what was done for MTL in #4923)? Happy to test any patch/topology.

Notes:
- The SoundWire slave on link 0: mfg_id 0x025d (Realtek), part_id 0x0712 (RT712), version 0x3.
- I don't know whether this RT712 is the SDCA "VB" variant; nothing probes it today due to the fallback. Can test/check on request.
- Willing to provide
acpidump, full dmesg, alsa-info snapshot, NHLT dump or test kernel/topology builds.

@pdaether Can you try #5901? And please share the full dmesg log.
pdaether commentedon Sep 6, 2026
I tested PR #5901. The new machine description appears correct, but the
machine_checkprevents it from matching this laptop.Test environment:
Exact PR #5901 result
I verified that the patched
snd_soc_acpi_intel_matchmodule was loaded (srcversion 3E2F7F7FA6CEEDF9A013E37). The result was still:The reason seems to be this line in the new entry:
SDCA_QUIRKS_RT712_VBrequires aSDCA_FUNCTION_TYPE_SMART_MICfunction, but this laptop's RT712 exposes only UAJ + SmartAmp. The laptop uses two PCH DMICs instead, matching the purpose of this new entry.Diagnostic test without the gate
I rebuilt the same patch with only the
.machine_checkline removed. No other PR behavior was changed. This works:ALSA then exposes:
PipeWire selects
Arrow Lake cAVS Speaker, and internal-speaker playback was tested and heard clearly. It also exposes the PCH digital microphone and headset microphone.Could the
snd_soc_acpi_intel_sdca_is_device_rt712_vbcheck be removed from this new link-0-only entry, or replaced with a check that accepts this RT712 UAJ + SmartAmp / PCH-DMIC configuration?Full redacted dmesg logs for both boots:

Oh, and thank you very much for your work!
It is the first time that I hear sound from this notebook without connecting a bluetooth headphone first, which wouldn't be possible without your work.
bardliao commentedon Sep 7, 2026
Yes, I can remove the snd_soc_acpi_intel_sdca_is_device_rt712_vb check. @jack-cy-yu FYI
bardliao commentedon Sep 7, 2026
@pdaether PR updated. Could you test it again? And can I add your
Tested-bytag in the patch?pdaether commentedon Sep 7, 2026
I retested the updated PR #5901 at commit 8181298 on the same Acer Aspire AV16-71P.
Test environment:
The updated module was loaded successfully and the RT712 configuration now matches. SOF loaded all expected function topologies:
ALSA exposes the expected playback devices, including Jack Out, Speaker, three HDMI devices, and Deepbuffer Jack Out. The previous No SoundWire machine driver found failure is gone.
Internal speakers and the microphone both are working.
The updated PR works correctly on this machine.
Yes, you may add my Tested-by tag to the patch. Thank you!
bardliao commentedon Sep 8, 2026
@pdaether Can you share your Tested-by tag? I can't find your email from github.
pdaether commentedon Sep 8, 2026
Tested-by: Patrick Daether daether@pd-digital.de
Tested on an Intel Tiger Lake laptop running Ubuntu 22.04. The audio playback issue is completely resolved by this patch.
bardliao commentedon Sep 9, 2026
@pdaether Sorry, could you test the updated PR again? I made some change to make the code more generic. Otherwise, it will impact all devices that with rt712 on link 0.
pdaether commentedon Sep 9, 2026
I retested the latest PR #5901 revision at commit 9b91e67 on the same Acer Aspire AV16-71P.
The expected patched module was loaded, the RT712 link-0 machine matched, and the previous No SoundWire machine driver found error did not occur. SOF loaded the expected function topologies:
I also physically tested both internal-speaker playback and microphone recording; both work correctly.

Thank you for your help @pdaether

I can confirm that the final PR revision also works on Arch Linux.
Test environment:
linux 7.2.3.arch1-37.2.3-arch1-3.1-acer-rt712sof-firmware 2025.12.2-1linux-firmware:20260810-21.6.80.5.17I rebuilt the official Arch
linuxpackage with commit9b91e670bd3fa6c98b35666ccaffc0882614e507applied. Since the Linux 7.2 source already containsrt712_0_agg_adr, only the 16-line patch from that commit was needed.The patched kernel boots successfully.
This confirms the same patch works with the Arch Linux 7.2 kernel configuration and packaging, in addition to the previous Ubuntu test.
