Good day all,
I hope this hasn’t been asked too many times, I’m using an Asus Chromebook C223 which uses the Intel N3350 - bluetooth audio works fine, I haven’t yet been able to test the audio jack but the built-in speakers definitely are not working and the only output I have in settings is “Dummy Output”
I have used mrchromebox to replace the firmware and am running the latest stable manjaro gnome distro, ChromeOS has been completely erased.

aplay -l shows the following:

Thank you in advance to anyone who can enlighten me in any manner.
