Manjaro ARM 19.12 Official Release - PineBook Pro

[spikerguy]

Has the sound output bug been fixed by an update yet or will it be fixed in a future release?

Kernel Updates

I installed a small program and that triggered pacman to update the whole system including the kernel. During this process, I realized kernel updates could be handled better:

Kernel updates delete the old modules and so the newly installed modules don't match the running kernel. The running kernel can't now load any further modules. I believe modules should never be deleted by the system (or at least in a much smarter way).

This becomes quite annoying. How do you guys work around this issue?

I can't even insmod a new module with the right path to it  in the old, running, kernel as it refuses to load modules from another kernel version.

Well… a new kernel means you gotta reboot to remain up to date – probably a good way to nudge you in the right direction with regards to having things as recent as possible no matter what

More seriously, though: You can either downgrade the kernel again until you've loaded the modules you need (if this doesn't happen too often), or see if one of the pre-made solutions work for you, like: https://aur.archlinux.org/packages/kernel-modules-hook (haven't tested that one, no guarantees for anything).

On servers, I like only allowing pre-signed modules in my precious kernels anyway – this would probably make this all more hellish. I should fiddle around with that on a desktop Arch someday, just for shits and giggles

/edit

Btw, this might be as good a place as any (as in: it's the Manjaro-Thread): I've finally managed to collect some odds and ends and PKGBUILDS I've made / modified for my own use on the PBP with Manjaro/Arch at https://github.com/lsfxz/pinebookpro-things. They might be of use to someone else but me, so I thought I'd share them.

With the new kernel users can mute the speaker using alsamixer or by passing the following commands.
Mute speaker so you can listen to audio on headphone.

Code:

sudo amixer sset 'Speaker' mute

Unmute speaker so you can listen to audio on speakers.

Code:

sudo amixer sset 'Speaker' unmute

This will only work with the latest kernel.
