Wii u minecraft game chat?

I'm currently playing minecraft on the wii you and in the online minigames i can't talk but hear others. What can be the reason?

That you can hear others is kind of strange. I've had Minecraft at wii u for two years, but I've never heard of anyone in the games. Can it be that you can adjust that in the settings?

You can change that in the settings.

Settings> Audio

Under audio is only "game chat" and that is activated. I've already tried what happens when I deactivate it and then I couldn't hear the others anymore…
