Fix for Pikmin 1 Wii SFX glitches?

Yesterday I dusted off my Wii U and homebrewed it and “legally acquired” digital versions of the Pikmin 1 and 2 Wii ports. While playing 1 I noticed the bulborbs (and swimming?) sounds are glitched which I find unpleasant and distracting. I learned from Google that this is an issue with the port, but I did not find any solutions. Is there a way to fix this on Wii U? And does this also happen in the Pikmin 2 port? thank you pickmimn reddit
