I have to say I'm nonplussed by this statement about the library I found at https://github.com/Arkq/openaptx

openaptx by Arkq is actually an alternative to libopenaptx (https://github.com/pali/libopenaptx). Prior to verion 3.1.0 of bluez-alsa only openaptx was supported (and would have to be built from source). Version 3.1.0 introduced the switch "--with-libopenaptx" to use libopenaptx instead. A binary version of libopenaptx is available from the normal Raspberry Pi OS repositoriy (package libopenaptx0).
