This is a general problem across game I tried but I will use Mario Kart as the example as it happens very early and repeatedly.
In the stable 5.0 this dpesn't occur, I get the normal shader compilation stutters and then next time I play its smooth. However I have been trying newer builds for bluetooth passthrough and in all of the ones I've tried I have some added sound stutter/FPS drops. The most easily reproducable one is in Mario kart DD. When ran and it shows the Ninteno logo and says "Nintendoooooo". The audio stutters and there is a momentary drop from 60 to 40fps. Again, in older builds this is completely smooth. Also it is repeatable, it does it every time so it definitely isn't shader compilation issues unless there something weird going on.
