For context, LDAC is one of the few wireless audio codecs stamped Hi-Res by the Japan Audio Society and its encoder is open source since Android 8, so you can see just how long Windows is sleeping on this. I’m excited about the incoming next gen called LC3plus, my next pair is definitely gonna have that.
I’ve had BT disconnect issues on a 2015 HP EB 840 G2 paired with my ancient Logitech UE speaker. Not sure if it’s the implementation of bluez on mxlinux or my actual bt hardware on the laptop. The result for me is similar to yours: laptop is flaky, so my phone remains my playback source of choice.
