Iam curious, do you play with sound ON or OFF ingame?
Personally i have not been playing Wow with any sounds since Vanilla, when MC, Naxx came i couldnt hear trough the cluttering of 40 people trying to lead the raid themselves, so I had to turn off the sounds in order to filter out whos actually was leading.
This has continued since that time.
Q: Why do you play with or without sound?
