Note that I don't expect to ever do this. The purpose of this issue tracker is mostly to remember to say "no" if someone asks if Hiby DAPs are (properly) supported.
Hiby has the SmartAudio SDK which replaces AudioTrack and can apparently reach higher sample rate or DSD playback on Hiby DAPs. For these devices, this SDK should optimally be used. This doesn't seem to be public, but one could ask joe0bloggs if they have a GPL-compatible version, or borrow it from Symfonium using Ghidra.
