[FEATURE] Xiaomi Redmibook 16 2024 mic is not working

[OrelSokolov]

So can anyone help with implementing firmware for this model?
What should I provide?

options snd-hda-intel dmic_detect=0 currently works for sound, but internal microphone does not work.
3.5 headset works.

Thanks.

UPD:
Windows works fine with internal mic, device info:

please share the output of 'alsa-info', it's not clear that it's an SOF problem but more likely a Linux hardware detection issue.

Looks like this issue is unrelated to SOF and is a platform issue with HDA mic integration.

[plbossart]

please share alsa-info without this "option snd_intel_dspcfg: dsp_driver=1"

[OrelSokolov]

@plbossart how to do this? I ran just alsa-info without any options.

[plbossart]

you have this option somewhere in /etc/modprobe.d/*.conf. Remove it, reboot and send the results of alsa-info.

[plbossart]

double check the results,
