Arch Linux ARM on PinePhone

[Danct12]

Unfortunately I have no outgoing sound on any phone calls, incoming or outgoing so I had to stop using Arch as my daily driver.

The worst: at times the phone will not wake once it goes to sleep. Hard boot and repeat. The above success occurred after I spent 3 hours trying various power/display/sleep settings. I had given up and was quite surprised the next morning when it responded. At times I also had sound issues, of the notification sounds, bark would work properly but the other three occasionally produced an identical whine/buzz

The phone goes flaky whenever a USB cable is connected or removed. However, power management is vastly improved once the phone is charged. I now ensure it is 87% charged (mine won't charge higher?) before doing any work with it.

Communication  between the modem and the OS still goes sideways after suspend/sleep. The icon will show no connection but the phone responds to incoming calls and texts but data does not work. A reboot is required for data.

As for sounds, you need to do pacman -Syuu to downgrade the PA package (if the repository was added before [core] order), the latest PA has issues on the PinePhone. On new images this is not needed.

As for the phone not waking up, this seems to only happen on Braveheart (also happens on newer if modem killswitch is off) and caused by USB driver hanging during suspend. Unfortunately it seems like a lot of us in Pine64 dev channel have talked about this and still hasn't come with a fix yet.

The phone only charges up to 88%, all of this started when megi implemented some battery safety feature to 5.9 kernel, I think there is a workaround for that in sysfs, but I'm definitely not going to turn that off or revert the changes.

Other than that, I'll look into other issues and I'm sorry for unsatisfied experience.
