 ### Unknown function info
 
+- [sceAudioSystemInit, sceAudioSystemProcessAdd, sceAudioSystemProcessRemove, sceAudioSystemProcessResume, sceAudioSystemProcessSuspend, sceAudioSystemTerminate](../../../core/libs/prx/libSceAudioSystem/Export.cpp) have unknown signatures and behaviour. The parameterless `int` declarations are import-resolution placeholders, not confirmed ABI signatures, and throw through `NotImplemented_nid_no_patch`. Only the names and NIDs are established by the [13.60 export inventory](https://github.com/xdCloudy/PS5-13.60-Function-Stub-Library/blob/bfec40deb4c47a17d7603ee2bc79aa6862c0c56b/data/firmware-13.60/libsceaudiosystem-bfe74a18cc.jsonl).
 - [sceAudioSystemSystemResume and sceAudioSystemSystemSuspend](../../../core/libs/prx/libSceAudioSystem/Export.cpp) (libSceAudioSystem) - names and NIDs are present in the [PS5 3.20 export inventory](https://github.com/DNNDHH/PS5-3.20_Libs/blob/b2a77c09cd71c01f34c790cfbe98c751a13262ad/libSceAudioSystem.c), but no credible prototypes were found. The declarations have no parameters solely to resolve known imports; this is not an ABI claim and callers must not call them until signatures are verified
