I’m pretty sure you can use aptx codecs using a Bluetooth 4.0 dongle and pipewire/bluez5. Just be aware when using them for gaming, if the game is cpu-bound and starved the system out of CPU time, the bluetooth audio might start to stutter. A Bluetooth audio dongle never stutter because they have their own independent Bluetooth stack, but they’re about 10x more expensive than a Bluetooth 4.0 dongle (~$50) and can only be used for audio only.
