I have a macro set up specifically for /script PlaySound(105675) which, prior to 9.1.5 would play a certain Loa laugh, I loved this, it was fun, I would share it with guildies or raid members, they’d play it, get a chuckle, all was well
And now…now I cannot Hek Hek Hek 
Sometimes, this happens. The quest completed macro got changed, before. The old one stopped working, but players found the new one.
…that worked? I thought they got rid of that years ago. Did it run off an addon, perhaps?
No, you could always use macros to play in-game sounds.
You could also manually type it in but that doesn’t work now either, for me, or my guildies
Probably a different identifier, maybe? I just looked up a few other sounds and they’re working just fine.
Also, I had no idea that was a thing…
Just went through all the options for Jani through brute forcing and it seems like half of them don’t play a sound at all anymore which is sad, I love Jani
