Just tried deleting my working prefix, letting steam create a fresh 4.11-1 prefix and running the same commands.. Everything works fine for me, including sound...
Can you check your volume mixer (e.g. pavucontrol) to verify that the game's audio output isn't muted or directed to some other audio device?
