The library registered no shutdown callback, so a guest mixer thread kept calling sceAudioOut2ContextPush while exit ran the static destructors and mixed from the freed port table (#5864). Exports that read the port tables or output audio now hold a guard: once exit starts they park the thread with LibcAwaitExit_nid_postfix, and the shutdown callback waits for the calls already inside. A push waiting for a grain from sceAudioOut2ContextAdvance also wakes on the shutdown token, so the callback does not wait for an advance that is parked.
Surround Sound Studio (PPSA99051) opens an Ex port for IEC 61937 bursts
when a clip is played. Follow the disassembly and console log in
sainsaji/PS5-Audio-Passthrough-Research: ExOpen refuses modes outside
mask 0x61F with 0x80260015 and opens an S16 stereo port of 256 frames at
48 kHz or 1024 frames at 192 kHz; ExConfigureOutput refuses a nonzero
first argument with 0x80268009 and returns 0 for the documented modes
and targets; ExClose returns 0. The host has no HDMI bitstream output,
so an Ex port has no device and drops its bursts at its own rate.

Palworld (PPSA23126, #2648) stops at start-up on the export, imported by
its bundled libdiscord_partner_sdk.prx:
FAIL: unresolved ELF import oiOi7vgPfAY from libSceAudioOut.prx
PPSA28416 imports it from its bundled party-ps5-shipping.prx as well. The
call itself has not been observed yet.
SharpProspero (5dfdb4b0, Interop/Audio/AudioOut2.cs:460-464) declares
`int sceAudioOut2EnableChat()`, "Allows chat audio alongside the
application's own", and the ps5-payload-dev SDK stub (f5d40f02,
sce_stubs/libSceAudioOut.c:62) exports it as well. There is no context or
handle to validate. The host mixes no chat audio and AudioOut2 has no chat
port, so the call records that chat audio is allowed (traced once with
APS5_TRACE_AUDIOOUT2) and returns 0. Whether the console fails it without
a chat session or when repeated is recorded in technical debt, and the
PPSA28416 "signature unknown" entry is dropped.
NID oiOi7vgPfAY matches tools/nid_names.py and the shadPS4 aerolib list.

sceAudioOut2PortGetState returned the two channels of the host output for
every port. It now reports the channel count of the port's data format and
clears the rest of the state, so the reserved fields no longer keep the
caller's stack contents. The speaker info and system state calls are
unchanged; a new test covers all three, since none had one.
The channel count follows SharpEmu, another emulator; no console
measurement exists, recorded in TechnicalDebt.md. ASTRO BOT and ASTRO's
PLAYROOM reportedly stop on an assertion that depends on the reported
state (#4317); which field matters is not isolated.

Gran Turismo 7 (PPSA01317) fails to load on unresolved imports and on
two needed libraries that AnyPS5 does not build (#4782).
- sceAppContentDownloadDataFormat empties /download0, as
sceAppContentTemporaryDataFormat does for /temp0.
- sceNpAuthSetTimeout returns REQUEST_NOT_FOUND for an unknown request
like the other request calls, and OK otherwise; no request reaches the
network the timeouts would bound.
- sceNpWebApi2PushEventSetHandleTimeout throws for an unknown library
context, like sceNpWebApi2GetMemoryPoolStats, and returns OK
otherwise; push event handles are not tracked and nothing waits on
one offline.
- sceSslDisableVerifyOption, sceSslGetAlpnSelected, sceSslSetAlpn,
sceSslSetMinSslVersion, sceAudioOutDeviceIdOpen and the unnamed
libScePsml NIDs xNZM9Y5lf-M and lcZD9tJraAw are declared without
parameters and throw; their signatures are unknown.
- libSceUsbStorage and libSceUsbStorageDialog exist with no exports,
like libSceXml: the title lists both as needed but imports nothing
from them.
Each assumption is recorded in the library's technical debt file.

Surround Sound Studio (PPSA99051), catalog build on main a11c8f7f with
the flat-interpolation fix, stops 16 s in, before its first frame
(orishamir, #3581 comment 6109839314):
sceAudioOutSysGetHdmiMonitorInfo not implemented
The call takes (type, out, size); out must be non-null, size exactly
0x180 and type 1 (HDMI) or 0x10 (sainsaji/PS5-Audio-Passthrough-Research
c3be9c2a, docs/FINDINGS.md section 3 and AGENTS.md:25, firmware 12.70).
Titles read the monitor name at +0x0B, the descriptor count at +0x94 and
8-byte descriptors from +0x98 (same, FINDINGS.md hardware log item 1 and
sample-app/src/platform/ps5/bitstream_out.cpp:92-128).
Audio reaches the host through SDL as PCM and there is no EDID, so type 1
with a 0x180-byte buffer reports a sink without a name or descriptors:
the buffer is zeroed and 0 is returned. Surround Sound Studio's
Passthrough page then lists no formats; EVO Player's code treats an empty
list like a negative return. A null buffer returns 0x80260004, as the
other AudioOut calls do. Type 0x10, other types and other sizes throw:
their results and error codes are not known.

Jelly5 (PPSA99505) imports sceAudioOutExGetMonitorInfo (PhnNN0UEV6Y),
sceAudioOutExConfigureOutput (VcE+gXSwFXI), sceAudioOutExOpen
(6X6dp+07h4U) and sceAudioOutExClose (0TfjSulCV2A) from libSceAudioOut
and fails to load because no library exports them. It calls them only
for its optional HDMI bitstream output, and their signatures are
unconfirmed, so they are exported without an implementation and throw
if they are called, like sceSaveDataCancel.
With SDL's disk driver no pad audio device is open, so AudioOut2MixPorts
runs with no pad output. A vibration port and a mono pad speaker port
are pushed together: only the speaker's data reaches the main mix, and
a vibration port alone leaves it silent.
Without a DualSense audio device every AudioOut2 port was mixed into the
main output, including PAD_VIBRATION ports. Their waveforms drive the
controller's actuators on the console and are never heard; mixed into
the speakers they made PPSA28997's combat about 20 dB louder than its
dialogue. Vibration ports are now left out in that case; pad speaker
ports still go to the main output.
A port kept only the last PCM buffer set before a push and played it again
at every later push without a new one. PPSA12544 sets one grain of a ring
buffer per call on its object port, often two or three between pushes and
then none for a few, so all but the last of each burst were dropped and the
stale grain repeated: a buzz on loud sounds and after a sound stopped.
Buffers set between pushes are now queued and played in order, at most 16
queued. A push without a new buffer repeats the last one only for a port
that has always been given the same buffer (rewritten in place, as the
timing tests do); a port whose buffers move on plays silence.

On Windows, nanosleep and this_thread::sleep_for/sleep_until go
through winpthreads, which ends a wait on a 15.6 ms GetTickCount64
step. Blocking sceAudioOutOutput and sceAudioOut2ContextPush calls
returned in bursts about every 16 ms, a blocking sceAudio3dPortPush
ran at about 68 % of real time, and sceAudioInInput without a device
woke anywhere from 1 ms to 31 ms apart. They now sleep with
PreciseSleepUs or the new PreciseSleepUntil.

PPSA01289 (Sackboy: A Big Adventure) calls sceAudioOut2MasteringTerm when it
replaces its world, which threw. Like Init and SetParam it has no effect, as
there is no mastering stage. The title creates its next world's audio device
before it destroys the previous one, so Init runs twice before Term runs
twice; whether the console reports an error for either is unknown, so both
return 0 and the case is recorded in TechnicalDebt.

Measured on a PS5 (firmware 13.60) through dlopen of libSceAudioOut.sprx:
a MAIN (type 0) port accepts 1, 2, 8 or 12 channels (bits 8-11) with
sample type 0 or 1 (bits 0-6). Bit 7 without 8 channels returns
0x80268001, any other unsupported format returns 0x8026800E, and both
write UINT64_MAX to the output handle. Bits 12-31 do not affect the
result. Other port types keep their current validation.

A captured grain stored only the port slot and data pointer, so a port
created in a destroyed port's slot before the next push mixed the old
pointer with its own format. Ports now carry a generation that the
capture records. TechnicalDebt notes that the last grain pushed before a
title stops is never played.

The host mixes without the console's mastering stage, so the mastering
parameters have nothing to configure, as with sceAudioOut2MasteringInit.
Accept them instead of aborting, keep throwing for a null parameter
block, and record SetParam next to MasteringInit in TechnicalDebt.

Address review: read a grain's buffers at the next push without spinning
under the context lock, keep the no-device model mixing at push time,
size the pad queue from the unplayed main grains again, use generic
names in comments and TechnicalDebt, and add audio_out2_timing (next-push
read, queue level beyond the cushion, priming after running dry).
