You have pipewire. It is compatible with pulseaudio. I find it very surprising that you don’t show aac. I am not familiar with sbc-xq, but Apple products don’t support ldac and my understanding is sdc is not useful for audio listening, but rather calls. My M4s work fine on my desktop with an intel ax201 Bluetooth chipset. I have been using aac there, but ldac worked I think. I had problems with the usb BT adapter before that though.
