I have noticed an odd notification sound when getting a proc or buff on certain specs. It’s very distracting, especially for enh and demo where I keep hearing the sound after combat has ended. I haven’t played for a while so I’m unsure when this was added, or if it’s an issue with my install. I have tried disabling all addons to rule them out. They aren’t doing it.
Edit: After some testing it’s tied to the default blizz spell alerts. If I turn them off the sound disappears. I’d rather not but will if I need to.
I have found 3 so far but I’m sure there are more. It sounds a little like the level up sound. fsshhh…fssshh…I think you get the idea.
enhancement, maelstrom weapon (sounds pulses)
demo, demonic core (sound pulses)
fury, rampage (just sounds once)
It seems to be tied to specific buffs becoming available as the sound stops when the buffs fall off. Rampage seems to be the oddity here as it doesn’t have a visual buff but it still sounds. I think I may have a trinket that does it too but I have to test more.
