Player sounds: It doesn't work?

[Sideos]

Hello guys,
I'm trying to put some music on players' chat messages.
For example, they type Comradeship and it will play Comradeship.
Now, this is NOT working. I actually don't hear it in-game. I made triggers so that the last played music will stop and the other will begin, but they don't actually play. Only 1 plays.

Please help?
This also happens with sounds. Only 1 plays.

Sounds tend not to play for the first time, it's some bug; even preload doesn't help. However, SoundUtils library seems to be working, so you can use that instead. Don't use Stop (Last played music) Immediately; stop the theme itself on the upper field.

Thank you, I'll be testing out.
It works perfectly on Island Defense map.
