📄 Description

sceAudio3dGetDefaultOpenParameters should only copy 0x20 bytes to the parameter output.
We were originally writing 0x28 bytes, which could corrupt the stack in titles using the function.

This fixes some cases of kernel.cpp:81 stack_chk_fail: Unreachable code! in games using libSceAudio3d.
