I recently installed an Arch-based linux distro (Garuda linux) and wanted to play WoW with it (Wine). Sadly I can't get the sound working. Took a while for me to realize it as apart from addons, I have muted the client. However not getting the sound working is an issue. I can tell the sound works on other ported apps and games so WoW is a special case here.

If yes the most easiest for no-advance people (you are on arch so you are suppose to be advance. Furthemore on weird distro, not fan of garuda). downgrade Wine.
