PetBattleAnnouncer 0.5
You know that feeling when you have disabled sound in WoW, are tabbed out and waiting for a PvP pet battle to pop? Yea that's right! What pet battle?! Blizzard have some how chosen to kill the notify sound, with the rest of all sounds, when a pet battle is found. Fear not, this nifty little lightweight workaround will fix that for you :)
Hope you like it, and if you do feel free to say thanks to Keksson @ Outland EU :)
