New addition to the OP.
Busybox 1.24.1 Installer:
As a byproduct of building my own static busybox compiles in all supported Android architectures for my latest AIK-mobile v2.0 package I figured I might as well offer them up separately as well since there aren't any providers making Android x64 builds, at least not for all of them when I went hunting (to try and save myself some time). The installer detects what architecture (ARM/ARM64, x86/x86_64, MIPS/MIPS64) your device uses and installs the correct busybox binary to /system/xbin accordingly; it detects and supports "systemless" root installation as well, installing to /su/(x)bin instead. It then cleans up any symlinks from a possible previous installation at that location and cleverly generates new symlinks directly from the output of the installed binary, so they always match.
My busybox configs and patches are available here: https://github.com/osm0sis/android-busybox-ndk
ARM has the most applets available, followed by x86 and MIPS. The x64 builds, due to being from the API 21 NDK, had some things fixed without requiring patches that were previously broken, but also introduced a few code errors requiring me to disable a couple applets that work for the other architectures. I've got a patch submitted to the official busybox mailinglist to resolve some API 21 compatibility too, so that will probably be added in a future version to save people time and make it easier for more providers. Anyway, hopefully I got all the applets most people want working. :good:
Edit: Now the zip will also clean up an installation made to /su/bin and then install to /su/xbin. :good:
Great work:good: Seems like yours busybox is the best solution to overcome several problems with our audio mod magisk module. Wonder if we can add this to mod, giving a credit for you? Users gonna benefit a lot from it.
