Internal microphone not recognized - Acer

The internal microphone isn’t recognized since day 1.
Externally attached microphone works just fine.

Too many Sound Servers?
Remove all and install manjaro-pipewire perhaps?

On a memory stick I tested the mic with MX Linux and it was recognized immediately. Thank you for finding the time ti read this:)

Onboard audio device is showing legacy driver snd_hda_intel in use that does not support internal digital microphone array on modern laptops. System needs Sound Open Firmware driver like snd_sof_pci_intel_tgl

Please post more information about ALSA devices

sudo --upload

If possible, use the script on MX Linux Live ISO to get information about a working sound system

Remove all and install manjaro-pipewire perhaps?

since the problem is likely within ALSA I suggest you disable PipeWire permanently:

systemctl --user mask pipewire.socket; systemctl --user mask pipewire.service

and disable PulseAudio:

systemctl --user disable pipewire.socket; systemctl --user stop pulseaudio.service

to isolate and resolve microphone issues in ALSA

When internal microphones are working in ALSA, PulseAudio can be turned on to check if it works without interference from PipeWire, or replace PulseAudio with PipeWire

here goes…

working on it…

I suggest you update system BIOS to latest version v1.11

Install or reinstall sof-firmware

pamac install sof-firmware

and remove the 3 modprobe options added to system

!!Modprobe options (Sound related)

snd_intel_dspcfg: dsp_driver=1
snd_hda_intel: model=dell-headset-multi
snd_hda_intel: power_save=1

Reboot system to ensure modprobe options are removed

Modprobe option snd_intel_dspcfg: dsp_driver=1 appears to be working to force use of legacy driver snd_hda_intel

The 3 modprobe options are suggested by Archwiki for models Swift 5 SF515-51T and Swift 3 315-52 with Realtek ALC256 audio codec.
I would not expect snd_hda_intel: model=dell-headset-multi to work for the headset jack on this system with ALC255 codec


Check check

Cannot find /etc/modprobe.d/modprobe.conf

Found the 3 modprobe options added to system

They are placed in swift5.conf instead of modprobe.conf

There’s also with exactly the same options. Delete the file or leave it be?

Removed the previously created by myself files while working on better battery performance etc

Appears I can finally hear myself :slight_smile:

Archwiki suggestion uses /etc/modprobe.d/swift5.conf
