Reckon CM4 is still a bit bottlenecked, but CM5 might finally be the answer? CM5 is supposed to be pin compatible with CM4, and should just be a drop in replacement.. Hopefully somebody can try and see if CM5 is the missing piece to the puzzle.
The thing I am unsure is - does x86_64 sound better because that's my primary focus? Perhaps some audio maker can donate a decent CM5 based board for me to play with and I can attempt to see what tweaks are available in software.
