Mario Party 8: Strange sounds during gameplay after Carnival Calliope

Hey all,

Wanted to play Mario Party again, only have a wii with it, so there I am.

Wanted to use my 800+ tickets, so went to the fun bazaar. There I listened to some sounds in the carnival calliope, also to some of Peach her sounds. Now after 1 or 2 turns, no matter what character I play, the Peach hurt sound plays, sometimes multiple times in a row. This makes playing the game very hard.

This only happened after the carnival Calliope and is persistent over restarts and even power cycles. Original Wii with original disc.

Tried to look up how to fix this, but can't really find a thing. Is this a known issue? How do I fix this?

EDIT: It happens when you move controller 2. You hear the taunt of that char + princess peach sound. Extremely weird.
