In-built Laptop microphone not being detected

Support Sound
,
1

I was messing around with my laptop’s sound settings using pagraphcontrol since my headset mic was picking up audio directly from my earphones, but on accident, I deleted some modules or the other trying to prevent audio streams from criss-crossing. This lead to my laptop’s microphone no longer being detected. I’ve tried some other solutions (which I’d share but I’m not allowed to share links or media yet). One of them was from the PulseAudio troubleshooting guide on the archwiki and the other suggested I try purging pulseaudio and pavucontrol, and then reinstalling them but they don’t seem to have worked.

Other threads that state a similar issue also mention a /etc/modprobe.d/sound.conf but the folder contained no such file. Might be because I deleted all the conf files in an earlier attempt to get it working.

Hello @N3r_0 :wink:

How? With rmmod or modprobe -r ? This only temporary. Reboot and the modules are loaded.

Maybe deleting/renaming the config? ~/.config/pulse
Restart then with

systemctl restart --user pulseaudio.service

All conf files???

Hi there! You’re the first person I get to talk to here! :smile:

I used pagraphcontrol to see all my audio devices at once (monitors excluded). You can select a module (that’s what I call them but I could be entirely wrong about the terminology there) or device and then press the delete key to stop using them or disconnect them from any particular source. If a reboot should get them back, then it didn’t do it for my mic for some reason.

Tried this. Went to the folder and deleted everything inside and restarted with said command. No dice and same situation as before. The files reloaded back but still didn’t detect the mic.

I assumed those were the conf files I deleted. I’m not really sure how I lost them in truth since I don’t remember moving to that specific directory to remove stuff. It could be related to the pagraphcontrol thing but I’m not really sure how it all links together.

Welcome to the forum :slight_smile:

Mh… as i understand the app loads modules temporary, so it does not write anything to ~/.config/pulse/default.pa . So every time you start this app, the modules get loaded it.

If it worked before, I would assume it is somehow related to the app, or maybe an update of the kernel or kernel module has removed the support for your mic somehow.

Does it work with alsa only?

arecord -f S16_LE -d 10 -r 16000 --device="hw:2,1" /tmp/test-mic.wav

Use the correct card and device:

--device="hw:<card number>,<device number>"

Play what you have recorded:

aplay /tmp/test-mic.wav

Tried with hw:2,0 as well just in case but both resulted in the same message.

This obviously doesn’t work since the previous command failed to record.

As an aside, I thought I’d throw this in here too

can you try my fix i posted here, since i also had big audio problems since i rebooted after an update recently: Pipewire contains pipewire-pulse executable and creates pipewire-pulse.service/socket

Tried it but still no dice. I restarted PulseAudio just to see if it needed a reboot but all the pulse related applications are having trouble starting and connecting to PulseAudio.
