Welcome to Manjaro forum @Shiranai

Consider updating system BIOS/Firmware to latest version 1.47

Please post more information about audio devices detected in ALSA

sudo alsa-info.sh --upload

inxi data shows onboard audio device Intel Sunrise Point-LP HD Audio (Realtek ALC255) is using snd_hda_intel driver that should support audio playback to speakers and headphone jack, but does not support internal digital microphones

Try this solution.

@nikgnomic Thanks, here is the alsa info

https://alsa-project.org/db/?f=6160bd66faef8864b82be667fe3c2178fc49ec81

Sadly I can’t update the BIOS/Firmware without installing windows, and I want to avoid that pain if possible.

@oneno I tried your suggestion but sadly it didn’t work.

Most of the data from ALSA looks OK but the analog output for audio playback does not have an incoming connection from PipeWire

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC255 Analog [ALC255 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

If connection from PipeWire was present, data would show: Subdevices: 0/1

I suggest test audio playback direct to ALSA device as there is no connection from PipeWire to block it

speaker-test -Dhw:0,3 -c2 -l2 -twav

If that works to play audio speakers, I suggest you check audio devices detected in PipeWire
