 ### Functional
 
+- [AudioOut2 port storage](../../../core/libs/prx/libSceAudioOut/src/AudioOut2Port.cpp) and its lock have process lifetime. Guest audio threads can still capture grains while the host runs static destructors; destroying the port table then races with queued-buffer removal. Explicit port and context destruction still release their entries. The host does not yet stop every guest thread before process finalization.

 - [sceAudioOut2EnableChat](../../../core/libs/prx/libSceAudioOut/src/AudioOut2System.cpp) (libSceAudioOut) takes no arguments and returns 0, as declared by [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Audio/AudioOut2.cs#L460-L464) ("Allows chat audio alongside the application's own"). The host mixes no chat audio and AudioOut2 has no chat port, so the call only records that chat audio is allowed. Whether the console fails it without a chat session, when repeated or before `sceAudioOut2Initialize` is unknown. [sceAudioOut2DisableChat](../../../core/libs/prx/libSceAudioOut/src/AudioOut2System.cpp) is the counterpart, imported by PPSA18216: it takes no arguments, returns 0 and records that chat audio is no longer allowed; its signature is not confirmed by a console measurement, and whether the console fails it without a chat session or when repeated is unknown.
 - [sceAudioOut2Set3DLatency](../../../core/libs/prx/libSceAudioOut/src/AudioOut2System.cpp) and [sceAudioOut2MasteringInit, sceAudioOut2MasteringTerm and sceAudioOut2MasteringSetParam](../../../core/libs/prx/libSceAudioOut/src/AudioOut2Mastering.cpp) (libSceAudioOut) have no effect: there is no 3D rendering or mastering stage.
 - [AudioOut2 contexts](../../../core/libs/prx/libSceAudioOut/src/AudioOut2Context.cpp) (libSceAudioOut) with an SDL device read a grain's port buffers at the next push, at least 100 us after the grain was pushed, and play the mix behind a 40 ms cushion that the queue level leaves out. When the hardware reads the buffers is not known. The timing follows a title whose mixer fills a buffer after pushing it, reuses it two pushes later, and may still be writing it when the next push follows within microseconds. The last grain pushed before a title stops pushing is never read or played.
