Losing audio after today's update
I also have some new audio issues after the Sept 17 update, never had a bit of audio trouble before now. Occurs on all characters: sound effects for skills, pets, player/NPC quotes etc. drop out first, with ambient audio remaining (music, environment sounds). Eventually music then environment both drop out too, and the game is completely silent. Alt-Tab back to Windows and adjusting/testing volume also produces no audio. Whatever this bug is, it takes exclusive control of system audio APIs and doesn’t let go. I have “mute client when in background” set by default, and sometimes (not always) unchecking then checking it again will bring game & Windows audio back. Otherwise restarting the client (or full Windows reboot in one case) seems to be the only way to sort it out.
Server probably doesn’t matter, but I’m on Kaineng.
