Yesterday I was playing Mario Galaxy for about 5 hours with no audio or visual issues whilst running at 4k. None what so ever. And today, I felt like messing with the DPS Emulation Engine. So I changed it from DSP HLE Emulation to DSP LLE Interpreter just to hear the results. Well the result was crackling and missing audio. So I changed it back. Well, the crackling still happens, just not as frequently. And a specific sound is missing, The sound of when Mario spins in a large star to shoot off. No sound from any of them. What on earth did I do? Is there a fix for this considering there wasn't even an issue until I tweaked the DSP Emulation Engine settings. And I did troubleshoot with lower resolutions to no avail.
