[SOLVED] Lenovo T14 Intel Internal Microphone not Working

Hello,

My Lenovo T14 internal microphone does not record any sound. I have pulseaudio installed but I cannot even get it to work with alsa.

- Running the following command and then playing with aplay has no sound at all.

arecord --duration=3 --format=dat test1.wav

- Here is what alsa lists as input devices:

arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC257 Analog [ALC257 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

- journalctl relative to ALC257

janv. 16 12:37:40 alexander-T14 kernel: snd_hda_codec_realtek hdaudioC0D0: autoconfig for ALC257: line_outs=1 (0x14/0x0/0x0/0x0/0x0) type:speaker
janv. 16 12:37:40 alexander-T14 kernel: snd_hda_codec_realtek hdaudioC0D0:    speaker_outs=0 (0x0/0x0/0x0/0x0/0x0)
janv. 16 12:37:40 alexander-T14 kernel: snd_hda_codec_realtek hdaudioC0D0:    hp_outs=1 (0x21/0x0/0x0/0x0/0x0)
janv. 16 12:37:40 alexander-T14 kernel: snd_hda_codec_realtek hdaudioC0D0:    mono: mono_out=0x0
janv. 16 12:37:40 alexander-T14 kernel: snd_hda_codec_realtek hdaudioC0D0:    inputs:

- I have also checked that microphone is unmuted in alsamixer.

- I have tried the suggestions in https://wiki.archlinux.org/index.php/Ad … ot_working but no luck.

- I have installed sof-firmware as suggested in https://wiki.archlinux.org/index.php/La … inkpad_T14 but did not try the CONFIG_SND_SOC_AMD_RENOIR since I have an Intel machine.

Please help

Re: [SOLVED] Lenovo T14 Intel Internal Microphone not Working

It turned out I had "snd-intel-dspcfg dsp_driver=1" in my /etc/default/grub that was an old driver.

Removing the line and running grub-mkconfig solves the problem (as suggested here -> "https://bbs.archlinux.org/viewtopic.php?id=260827"
