Not sure if anyone else has as niche of a problem as i do but i've been running SM64CoopDX on Xbox Series X in Developer Mode via the UWP port and have run into what I believe is a platform-specific bug with external audio loading through the Character Select mod. The custom character voice files do not play on Xbox UWP regardless of audio format. I've tested with the Peter Griffin character mod (OGG files) and the official Extra Characters PLUS pack, both are completely silent. The model and movesets load and display correctly, but no custom audio plays; it either falls back to Mario's voice or plays nothing at all. If anyone has any ideas or workarounds, it would be greatly appreciated.
