Strang Pokemon Colloseum sound

[Shonumi]

Looking at the Dolphin Wiki entry for that game, HLE audio is choppy, but LLE audio solves that issue. Though LLE audio needs to have near full-speed so that it doesn't encounter any issues itself. It'll also demand more from your hardware. LLE audio requires you to dump your DSP files from your console. There's a guide here. If you have a quad-core CPU, it's probably best to enable "LLE on Thread" so Dolphin can use a separate thread to process the audio and give you some more performance.
