my Lalafell loses her voice when emoting with other players targeted

Time: 2015/8/10 6:45 JST
Frequency: always
World name: Sargatanas
Character name: Arche Koeln
Race: Lalafell F
NPC name: none
Monster name: none
Class/Level: weaver/60
Party or solo: solo
In-game time: 9:45 server time
Area and coordinates: everywhere
Steps:
1. Pick an emote that makes noise (eg., Huh, Surprised, Angry, Laugh, Chuckle, Cheer, Happy)
2. Target anybody but yourself
3. use the emote
4. The emote text appears in the log like normal, but no sound comes out

If I target myself, a minion, or have no target, it works like normal.
I can also hear other players' emotes targeting me without problem, just not my own targeting them.
