        Bug ID: 214995
       Summary: Sof audio didn't recognize Intel Smart Sound (SST)
                speakers, microphone and headphone jack
       Product: Drivers
       Version: 2.5
Kernel Version: 5.11.0-40-generic
      Hardware: Intel
            OS: Linux
          Tree: Mainline
        Status: NEW
      Severity: high
      Priority: P1
     Component: PCI
      Assignee: drivers_pci@kernel-bugs.osdl.org
      Reporter: nicolarevelant44@gmail.com
    Regression: No

Created attachment 299549 --> https://bugzilla.kernel.org/attachment.cgi?id=299549&action=edit The output of dmesg and lspci -v

I have a Huawei Matebook D15 notebook with Intel Smart Sound Technology as sound card. SST includes speakers, microphone and headphone jack so none of the 3 work. Bluetooth and USB headphones work. I have already tried to change "options snd_intel_dspcfg dsp_driver" and reload alsa (alsa reload) for each value but nothing (only small changes in dmesg). The first lines of dmesg_dump.txt are errors because of the 'alsa reload' command. The log is verbose because I add some options from this web page: https://thesofproject.github.io/latest/getting_started/intel_debug/suggestio...

My sound card is listed in PCI so the last lines of dmesg_dump.txt are the output of the 'lspci -v' command

aplay -l shows only 3 HDMI outputs with sof-hda-dsp

Hi Nicola,

Thanks very much for the report and sorry for the problem.

It's possible there's a power management issue, e.g., reads to the 00:1f.3 device are timing out because the device is in D3cold, but I can't tell from the part of the dmesg log you attached. In that case, reads will generally return ~0 (0xffffffff), but it looks like some reads *do* return valid data, e.g.,

sof-audio-pci 0000:00:1f.3: DSP detected with PCI class/subclass/prog-if info 0x040100 sof-audio-pci 0000:00:1f.3: found ML capability at 0xc00

I don't see an obvious PCI core connection here, so I cc'd the SOF maintainers in case they have any insight.

• It looks like you're running v5.11.0. Can you reproduce the same problem on a current kernel, e.g., v5.15? It's possible the problem has been fixed since v5.11.

• Did this ever work? In other words, is this a regression? If so, what's the newest kernel you know of that *did* work? In the worst case, we could bisect to identify a change that broke it.

• It might be useful if you could attach the complete dmesg log and output of "sudo lspci -vv" to the bugzilla.

That seems like a known issue already tracked at https://github.com/thesofproject/linux/issues/3248

There's a set of devices based on the ES8316/36 I2S audio codec which needs dedicated quirks. In the existing reports the Huawei Matebook D15 is listed as using that codec.

The latest experimental code we have is here: https://github.com/thesofproject/linux/pull/3107/commits

If confirmed, can we track this on GitHub so that all results for this sort of devices are collected in one place? Thanks!
