Everything sounds like it's underwater. Occassionally the real sound chimes in, but it dies and goes back to swimming under water again. It's quite frustrating. Unfortunately, I can't tell you how to replicate this because it just started with the new update. It's only RO, other Steam games and non-Steam games are perfectly fine. I've fiddled with all the audio settings and messed with the .ini and did a complete reinstall--no go.
