Manjaro ARM 19.12 Official Release - PineBook Pro

[DrYak]

I upgrade my system and I don't have sound, functions keys or wifi... ;(

for sound, once you have upgrade (pacman -Syu) :

Code:

alsamixer

then go to the far right of the mixer and enable (hit 'M') the headphone DACs:

• Left Headphone Left Mixer DAC
  
• Right Headphone Right Mixer DAC
  

For me, that made the sound work simultaneously on speaker and headphones.
(though no detection of jack and muting speakers)

But the speaker are extremely noisy if there's no sound playing (it seems/sounds that their level is left floating when there's no output)
