Internal Microphone ALC3204 does not work on Dell Inspiron

Hi,
i am using a Dell Inspiron 13 (5391) with Archlinux. I have the latest updates installed. Sound is working fine, but i cannot get the microphone working. I have no pulseaudio related packages installed. I have installed alsa-utils, alsa-ucm-conf and sof-firmware. In alsamixer i have unmuted everything and turned up the volumes.

When i try to record and play with arecord/aplay, i cannot hear anything i spoke but only acoustic noise:

$ arecord --duration=5 --format=dat test.wav
Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
$ aplay test.wav 
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo

Any idea how i can get the internal microphone working?

Some more output:

$ arecord -l

Re: Internal Microphone ALC3204 does not work on Dell Inspiron

If you're currently setting the snd-intel-dspcfg or dmic_detect=0 parameters you need to remove them since as mentioned in that thread this will expectedly disable the mic.

FWIW have you tested whether the second mic works?

arecord -Dhw:0,2 test.wav

Re: Internal Microphone ALC3204 does not work on Dell Inspiron

My kernel command line has none of the mentioned parameters and my /etc/modprobe.d/ is empty.

Second mic seems not to work.

$ arecord -Dhw:0,2 --duration=5 --format=dat test.wav
arecord: main:831: audio open error: No such file or directory
$ arecord -Dhw:0,1 --duration=5 --format=dat test.wav
arecord: main:831: audio open error: Invalid argument

I have updated the output of arecord -l in the first post. It has 4 sofhdadsp devices now. But still no success in recording from the first microphone device

Re: Internal Microphone ALC3204 does not work on Dell Inspiron

? So you did originally have one of these parameters since the current output aligns more with what I expect to see if they aren't present. Do the other mic(s) work?

Re: Internal Microphone ALC3204 does not work on Dell Inspiron

Until yesterday i have had the kernel parameter snd_hda_intel.dmic_detect=0 set. But as far as i remember i removed that before posting here. Maybe i recorded the old arecord list before that change.

The other mics do not work:

$ arecord -Dhw:6,0 --duration=5 --format=dat test.wav
ALSA lib confmisc.c:165:(snd_config_get_card) Cannot get card index for 6
arecord: main:831: audio open error: No such file or directory
$ arecord -Dhw:7,0 --duration=5 --format=dat test.wav
ALSA lib confmisc.c:165:(snd_config_get_card) Cannot get card index for 7
arecord: main:831: audio open error: No such file or directory
$ arecord -Dhw:1,0 --duration=5 --format=dat test.wav
ALSA lib confmisc.c:165:(snd_config_get_card) Cannot get card index for 1
arecord: main:831: audio open error: No such file or directory

Only device 0 works, but i cannot hear what i said into the microphone.

$ arecord -Dhw:0,0 --duration=5 --format=dat test.wav
Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
$ aplay test.wav 
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
