# libSceVoiceChat technical debt

### Silent stubs

- [sceVoiceChatDeleteRequest, sceVoiceChatInitialize, sceVoiceChatProcessEvent and sceVoiceChatTerminate](../../../core/libs/prx/libSceVoiceChat/Export.cpp) (libSceVoiceChat) - console behavior for these lifecycle, event, and request calls has not been measured; the current exports return success without managing sessions or requests, allowing offline titles and test suites to proceed without connecting to a voice chat daemon.
- [sceVoiceChatAbortRequest, sceVoiceChatRegisterChannelEventHandler, sceVoiceChatRegisterDaemonEventHandler, sceVoiceChatRegisterMemberEventHandler, sceVoiceChatRegisterPartyUserStateChangedHandler, sceVoiceChatRegisterVoiceEventHandler, sceVoiceChatStartAccessibilityEvent, sceVoiceChatStartChannelEvent, sceVoiceChatStartDaemonEvent, sceVoiceChatStartMemberEvent, sceVoiceChatStartRangedMemberEvent, sceVoiceChatStartVoiceEvent, sceVoiceChatStopAccessibilityEvent, sceVoiceChatStopChannelEvent, sceVoiceChatStopDaemonEvent, sceVoiceChatStopMemberEvent, sceVoiceChatStopRangedMemberEvent, sceVoiceChatStopVoiceEvent, sceVoiceChatUnregisterAccessibilityEventHandler, sceVoiceChatUnregisterChannelEventHandler, sceVoiceChatUnregisterDaemonEventHandler, sceVoiceChatUnregisterMemberEventHandler, sceVoiceChatUnregisterMicEventHandler, sceVoiceChatUnregisterPartyUserStateChangedHandler, sceVoiceChatUnregisterRangedMemberEventHandler, sceVoiceChatUnregisterVoiceEventHandler](../../../core/libs/prx/libSceVoiceChat/Export.cpp) (libSceVoiceChat) - offline handler registration and event controls return 0 without connecting to a voice chat daemon, because the host environment does not run a PSN voice chat service; titles that register event listeners or start/stop audio capture events proceed safely without throwing
- [sceVoiceChatRegisterHandlers and sceVoiceChatRegisterMicEventHandler](../../../core/libs/prx/libSceVoiceChat/Export.cpp) (libSceVoiceChat) - they keep no handler and return 0 without connecting to a voice chat daemon, so no handler is ever called; the handler table's layout and the handlers' prototypes are not identified. The signatures come from one disassembled title (PPSA21564 01.007.000), not from a console: it calls `sceVoiceChatRegisterHandlers` (0x2e473c) with a 0x30-byte structure of six function addresses and a user argument, then `sceVoiceChatRegisterMicEventHandler` (0x2e4751) with the 32-bit value it also passes as the user id of `sceNpWebApi2CreateUserContext`, a function address and the same user argument, and treats a negative result from either as failure

### Unknown function info

- [libSceVoiceChat additional exports](../../../core/libs/prx/libSceVoiceChat/Export.cpp) - these name/NID pairs are present in the inspected export inventory. Parameter lists, return types and behavior are unverified. Parameterless `int` declarations are import-resolution placeholders, not verified ABI prototypes; every entry throws through `NotImplemented_nid_no_patch`. No runtime functionality is implemented.

The inventory label is not authenticated retail-firmware provenance. The inspected image contains raw module-parameter words `0x13590001` at +0x10 and `0x13600007` at +0x14. Using the [published static ELF membership procedure](https://github.com/boykopovar/AnyPS5/pull/12367#issuecomment-6470603298), its 37 unique function NIDs have sorted-LF SHA-256 `6ae782ec9803eb89b69814a4687c2e7e25940b3f26e48dde34f0abd465cd2448`; all 2 entries below are present. This digest identifies the function-NID set, not the whole binary or its ABI. An independent review on [this PR](https://github.com/boykopovar/AnyPS5/pull/11935#pullrequestreview) corroborated these identities using a separately reported 13.42 reference; that does not establish matching binaries, prototypes or behavior.

| Name | NID |
| --- | --- |
| `sceVoiceChatRegisterMicEventHandler2` | `hVf-dQZU4nE` |
| `sceVoiceChatUnregisterMicEventHandler2` | `Jra48Mpq8+Q` |

- [sceVoiceChatGetActiveChannel, sceVoiceChatGetChannelMemberActiveChannelMatchingState, sceVoiceChatGetChannelMemberVoiceConnectionState, sceVoiceChatGetChatChannelMemberInfoList, sceVoiceChatGetChatGroupMemberInfoList, sceVoiceChatGetMicState, sceVoiceChatGetUserVoiceVolumeGain, sceVoiceChatRegisterChannelEventHandler, sceVoiceChatRegisterDaemonEventHandler, sceVoiceChatRegisterMemberEventHandler, sceVoiceChatRegisterPartyUserStateChangedHandler, sceVoiceChatRegisterVoiceEventHandler, sceVoiceChatRequest0, sceVoiceChatRequest1, sceVoiceChatRequestAcsTts, sceVoiceChatRequestAction, sceVoiceChatRequestSetMemberVolume, sceVoiceChatRequestUpdateGameSessionVoiceChatChannelName, sceVoiceChatRequestUpdatePlayerSessionVoiceChatChannelName, sceVoiceChatSetUserVoiceVolumeGain, sceVoiceChatStartAccessibilityEvent, sceVoiceChatStartChannelEvent, sceVoiceChatStartDaemonEvent, sceVoiceChatStartMemberEvent, sceVoiceChatStartRangedMemberEvent, sceVoiceChatStartVoiceEvent, sceVoiceChatStopAccessibilityEvent, sceVoiceChatStopChannelEvent, sceVoiceChatStopDaemonEvent, sceVoiceChatStopMemberEvent, sceVoiceChatStopRangedMemberEvent, sceVoiceChatStopVoiceEvent, sceVoiceChatUnregisterAccessibilityEventHandler, sceVoiceChatUnregisterChannelEventHandler, sceVoiceChatUnregisterDaemonEventHandler, sceVoiceChatUnregisterMemberEventHandler, sceVoiceChatUnregisterMicEventHandler, sceVoiceChatUnregisterPartyUserStateChangedHandler, sceVoiceChatUnregisterRangedMemberEventHandler, sceVoiceChatUnregisterVoiceEventHandler](../../../core/libs/prx/libSceVoiceChat/Export.cpp) (libSceVoiceChat) - parameter layouts are inferred; offline, handlers and event controls return 0, query calls, volume gain controls, and requests return `SIGNED_OUT` (0x80550006) without modifying guest buffers
- [sceVoiceChatRequestCreateVoiceChatGroup, sceVoiceChatRequestJoinVoiceChatGroup, sceVoiceChatRequestLeaveVoiceChatGroup, sceVoiceChatRequestDeleteVoiceChatGroup](../../../core/libs/prx/libSceVoiceChat/Export.cpp) (libSceVoiceChat) - assumed to take a request id and two pointers like the other `sceVoiceChatRequest*` calls; offline, every argument is ignored and `SIGNED_OUT` is returned, as for those
