libSceAudioIn technical debt

Silent stubs

• sceAudioInInit (libSceAudioIn) - returns 0 without library-wide setup, as sceAudioOutInit does; each sceAudioInOpen opens its own SDL capture device

Functional

• sceAudioInIsPadEmbeddedMic (libSceAudioIn) - returns 0 for every open port: on the console it returns 1 when the port captures from the controller's built-in microphone and 0 for another input device, but ports here capture from the host's default input device
• sceAudioInHqOpen, sceAudioInAsyncOpen - PS5 wrapper validation requires 48000 Hz followed by exactly 128 samples for both calls; HqOpen then requires format 2. The host uses the same SDL capture path for both, so native asynchronous scheduling and high-quality processing are not reproduced. Common port validation, device selection and host capture pacing remain incomplete. One title (PPSA03355, in its libfmod plugin) disassembled for this entry calls sceAudioInAsyncOpen from one call site (0xe5972) with index 0, 128 samples, 48000 Hz and a last argument of 2, plus a type argument of 0 or 1, which agrees with the 48000 Hz and 128 samples above; it stores the result in a slot of its own and branches on a negative result. What the last argument 2 means is not shown.
• sceAudioInGetGain, sceAudioInGetRerouteCount - GetGain writes 1.0f before handle validation and returns 0x80260105 for a null output, as confirmed by the PS5 module. Native handle bit checks and uninitialized/inactive port errors differ from the host port table. Native reroute counters follow device reassignment; the host opens each SDL device once and reports zero.
