TL;DR
Preferences set in ~root/Library/Preferences/bluetoothaudiod.plist
don't seem to have any effect any more. “Bluetooth Explorer” and defaults(1)
commands that messed with these don’t seem to work either. Does anyone know how to go about doing these things in Monterey?
Historically, we pedants and audiophiles on macOS have been able to tweak bluetoothaudiod.plist
to our own fancy. We were essentially restricted to setting AAC bitrates, toggling AptX (not AptX HD, mind you), and packet buffer limits and stuff, but it was still something.
The way to go about this in GUI was to use “Bluetooth Explorer”, an Xcode "extra" that is last known to have been distributed with Xcode 11.
Of course, one could always use defaults(1)
as well.
As GianpaoloPascasi points out in a post below, tweaking BT-audio codecs can sometimes be a necessity.
How does one tweak the stuff that Bluetooth Explorer and bluetoothaudiod.plist
managed, in Monterey?
