I don’t know why, but after launching the Homebrew Channel, loading WiiMC, and then returning to the system menu, the Wii’s audio playback appears distorted, as if the bitrate has been slightly reduced.

If anyone here is familiar with audio engineering or music production, it sounds as if there has been applied a bitcrusher effect to the audio. That’s the best way for me to explain it, whatsoever.

It only resets back to normal after the Wii has been turned off.
