I've a small update on headphone and speaker audio for all of you. https://gitlab.manjaro.org/tsys/linux-pinebook-pro does now feature control over the speaker amplifier and working headphone detection. Thus in tools like pavucontrol you can now select headphone output and actually have your speakers disabled.
Note that the kernel sound subsystem does not automatically disable the speakers when headphones are plugged in. However the headphone jack is exposed as an input device, thus an input daemon like acpid can be used for automatic switchover.
That are good news ... mostly.
In the past, there was a whine while playing audio. It continued for two seconds and vanished.
With the new kernel (or other Manjaro changes?), the whine is permanent. I only get rid of when disabling audio in pavucontrol.
Can anyone else confirm this observation?
