To be fair. AptX in general is niche and proprietary. That fact that regular AptX and LDAC can be enabled with one command is awesome considering they’re proprietary.
Generally, if anything is a standard it’s added much more quickly than other platforms so I wouldn’t call it useless. It’s a shame because Linux really has the best Bluetooth stack. It just works.
I’m hopeful SBC-XQ gains traction, even if I prefer an uncompressed stream, at least we have a better A2DP standard. Linux already supports this so it’s ahead of the game.
