Please remove snd_hda_intel: dmic_detect=0, you must set dmic_detect=0 somewhere.

[Adam Dyess (addyess)]

Thanks... that at least lets them show up in gnome.. but my internal audio array isn't an option. If i plugin an analog mic it works though. Just the realtek audio array doesn't work

[Hui Wang (hui.wang)]

If you remove dmic_detect=0, your alsa card could not be showed up in gnome. So I guess there are some errors in the audio driver initialization, I need the log to debug.

Could you remove dmic_detect=0 temporarily, then boot and upload the dmesg, let me see what happens on the audio driver.

[Adam Dyess (addyess)]

OK, Let's see if this helps you narrow it down. This file is with dmic_setting=0 removed from the grub cmdline

[Adam Dyess (addyess)]

and this is dmesg with the dmic_setting

[Adam Dyess (addyess)]

Maybe it's the "HP Wide Vision FHD Camera" which should be treated as a camera and microphone? i see it register with uvcvideo in both.

[Adam Dyess (addyess)]

hmm... it says that same message here

snd-intel-dspcfg.dsp_driver=1 is set in the command line. But later on it says i should pass that option.

[Adam Dyess (addyess)]

Looking at this: https://bugzilla.kernel.org/show_bug.cgi?id=205959 i tried editing the
/etc/modprobe.d/alsa.conf to have the option... restarted... same output

[Adam Dyess (addyess)]

Triumph is ours! My internal mic is working and can record audio. It's like a have an actual laptop without having to lug around another mic! Hooray

I found two files in /etc/modprobe.d that were turning off the dmic_detect.

➜ egrep -r dmic /etc/modprobe.d
/etc/modprobe.d/alsa-intel-dmic.conf:#options snd_hda_intel dmic_detect=0
/etc/modprobe.d/intel-audio-fix.conf:#options snd-hda-intel dmic_detect=0

Status changed to 'Confirmed' because the bug affects multiple users.

[lavistam (lavistam)]

I have the same problem as this thread. Unfortunately I don't have dmic_detect in the config files.

Here it my information. The laptop is a Lenovo X1 Extreme Gen3

I have a new laptop and my mic isnt recoginzed by ubuntu (18.04 or 20.04)

$ uname -r
5.4.66-050466-generic

I've been playing with settings to try to get:

snd_hda_intel

to work, and then got lost trying to replace it with sof-firmware per:

https://askubuntu.com/questions/1203799/internal-microphone-not-detected-lenovo-carbon-x1-7th-gen-ubuntu-19

and also

https://mathieularose.com/ubuntu-19-10-on-lenovo-thinkpad-x1-carbon-7th-gen/

Currently commented blacklist like so:

```
# blacklist snd_hda_intel
# blacklist snd_soc_skl
```

Which allows my speakers, but not my mic

If I uncomment, I can't see either. I have a thinkpad dock, so some "mic" is identified through the thunderbolt dock, when I unplug it, I have no mic recognized
