pavucontrol shows no output device
aplay -l just shows hdmi devices....

cat /proc/asound/cards
 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xc2b18000 irq 126

Any ideas?
edit:some more info

journalctl -b0 | grep snd_hda

did this just start happening after an update?

i only ask because of this thread from today

well it worked when it was a chromebook :grimacing: but not with manjaro......
anybody any ideas?
shame if the sound doesn't work as it's a decent little thing to use when 'out n about'....

ok, so it's never worked with manjaro. read through the arch wiki's for alsa/pulseaudio/chromebook

try this first:
sudo nano /etc/modprobe.d/alsa.conf


options snd_hda_intel index=1 model=,alc283-chrome
