Does anybody know what happened after this discussion? Is this long
overdue upgrade on the roadmap?
As Bluetooth headphones continue to grow in popularity (AirPods, Bose,
Sony and many of the smaller brands now), so does the demand for high
quality codecs. SBC is not one of them:
At best, it is comparable to mp3 128kbps or 192kbps if you are lucky. It
is not noticeable on the AirPods, but quite so on the Bose QC35 and even
more so on the Sony MDX-1000X.
Currently, SBC is hardcoded into the Bluetooth module, for example
and no other codecs are ever mentioned outside of the headers file
imported from BlueZ.
Meanwhile, bluez-alsa has had support for both AAC and apt-X for the
last 2 years:
while BlueZ in general has had it since the v3 branch.
Android started supporting full range of Bluetooth codecs in Oreo and
Apple products including MacOS have had them for a while. Since Ubuntu
uses PulseAudio, this leaves the headliner of Linux world far behind.
