Aztecia

RS audio disappears from my headphones during the loading splash screens - when I alt-tab and switch my audio to my headphones directly (instead of via my Elgato mixer) it returns. It happens at that EXACT SPOT - the little Rockstar logo - every time. My boss is potentially having the same issue and while his is more critical than mine, if I can get mine fixed, I can hopefully get his fixed. Full video of mine here: Any ideas??
