Have you ever been in a situation where there is a kiwi, hit sound or win sound playing and you want to know who's it is or you just want to show off your new sound but everybody thinks it's your opponents

Maybe there could be like a speaker icon next to the name of the guy playing the sound

You could always just ask it in the server.
I'm also not sure if this is just for me but both kiai's play during the start of a match. This would just show two speaker icons and you wouldn't have gained anything.
