That brings me to my questions:
Theres also another question on this topic but it was authored in 2014
The latest PulseAudio includes support for aptX. This is version 15.0 released on 2021-07-27.

PulseAudio now supports the LDAC and AptX codecs for A2DP. In order to use them (...)
Ubuntu 20.04 is running version 13.99.1.
$ pulseaudio --version
pulseaudio 13.99.1
The original creator was no longer able to maintain the PPA he had for supporting this. Someone else took over managing a PPA using the original creator's sources.
