Meanwhile, there seem to be packages @ https://github.com/EHfive/pulseaudio-modules-bt/issues/20#issuecomment-461503659 — and LDAC in Fedora is pending legal review, apparently.
(And packages for more distros @ https://github.com/EHfive/pulseaudio-modules-bt/wiki/Packages FWIW)
@garrett Aaand it really works, that's übercool!
@sesivany I restarted Pulseaudio (after restarting Bluetooth earlier) and got a few minutes to test it out on my Fedora 29 laptop:
1. LDAC from laptop to FiiO Btr3.
2. LDAC from laptop to Sony XM3 Headphones.
3. AptX HD from phone (OnePlus 6T) to laptop. Not sure why it's AptX HD instead of LDAC, but it's fantastic enough too. 😉
This is nice.
@sesivany Just playing around and selected input from my headphones and it dropped the audio down to HSP/HFP. Ouch. It's possibly even worse than a walkie-talkie.
(This is a shortcoming of Bluetooth audio. There's no hi-res (or even medium-res) audio output with input at the same time, sadly. Thankfully, it's easy enough to switch back to A2DP with LDAC... even in GNOME settings.)
Generalistic and moderated instance.
