[SOLVED] Built In laptop Audio not working

Hello everyone,

I'm pretty new to Arch Linux and I'm having a issue with the built in audio from my laptop. It does not get detected, but, I'm able to listen to audio on my Headeset(USB) and from the external monitor(HDMI).

Outputs:

I'm using pavucontrol to control the audio volume. There's no device for the built-in audio.

Is there any chance that anyone can give me a hint on how to fix this?
If there's any more info that I can provide please let me know.

Thanks in advance.

Re: [SOLVED] Built In laptop Audio not working

In general from the module list, ensure sof-firmware and alsa-ucm-conf are installed. if that doesn't help, which laptop model is this exactly?

Re: [SOLVED] Built In laptop Audio not working

Thank you so much V1del, you have no idea how much time i've spent trying to fix this. It's now working! It's a Omen 15 laptop btw.

Seriously, You made my day.

Best regards,
