did you try to play with alsamixer ??
I ve just tried the live iso of endeavouros (may 2023), played a little bit with alsamixer (headphones and dac settings) and I got sound ! endeavouros also recognized the wifi card ! … I think I am going to install it 
EDIT : installed endeavouros (may 2023), audio and wifi working great as I said 
(for the sound you need to play a little bit with headphones and dac settings in alsamixer)
BUT microphone is still not detected
