HP x360 1040 G5 - no internal Microphone

[3ddd]

I have no internal Mic on my Ubuntu 20.04 with mainline Kernel 5.9. Any idea how to fix that?

@3ddd looks your platform is KBL, which is not supported by SOF driver. https://github.com/thesofproject/linux/blob/topic/sof-dev/sound/pci/hda/hda_intel.c#L2458

/* Kabylake */
{ PCI_DEVICE(0x8086, 0xa171),

[3ddd]

Is there another Linux driver supporting this? Or is Windows the only solution for this Problem?

[plbossart]

There is already the skylake sst driver taking care of this device.

I am afraid you've hit an issue with this driver.

I would use 'options snd-intel-dspcf dsp_driver=1' in /etc/modprobe.d/alsa-base.conf to see if the legacy driver works on playback for you. If you see a Conexant codec you are probably out of luck, this is a configuration not supported by this driver.

[3ddd]

i see no difference with the dsp_driver=1 -> http://alsa-project.org/db/?f=173ba2a7dfc88d6ef4efb28b1e9d6a6848f7a4b7 where should i see the Conexant Codec? Any Chance to fix that in SST Driver? Where is the right place to ask for that?

[3ddd]

To activate Playback i could use this: https://askubuntu.com/questions/1243369/sound-card-not-detected-ubuntu-20-04-sof-audio-pci

snd_intel_dspcf: dsp_driver=1

typo: was dspcfg...

see https://thesofproject.github.io/latest/getting_started/index.html#debugging-audio-issues-on-intel-platforms

ok, now i have playback but no DMIC. Also there is a Conexant Codec now - so then i am out of luck and have to use Windows? http://alsa-project.org/db/?f=951b7476be2a5837dc680ef2c75a6daf1235be3c

[plbossart]

ok, now i have playback but no DMIC.

that's 'normal', it was just to detect the codec.

Also there is a Conexant Codec now - so then i am out of luck and have to use Windows?

I am afraid we don't have a solution at the moment. There was a decision that KBL would not be supported by SOF, but since the other driver doesn't work with Conexant codecs that leaves mainly HP users without a solution.

[3ddd]

Thank you anyway.

[keyonjie]

@3ddd we won't provide fix from SOF side, close it here.
