An incomplete startup command list consumed both layout detection and the
one-time DeviceSink scan, leaving valid SDK 4 audio frames permanently
silent. Keep both decisions pending until a supported layout walks the
whole list, as proposed in PR #331.
Extend the reproducer with valid-first and incomplete-startup stereo PCM
checks for SDK 4, 6, 16 and 21, and document the finding.

Apply PR #262's device-buffer fix for clicks caused by audio underruns.
Reconfigure on both output-device and hardware sample-rate changes, respect
the device's frame range, and read back the actual buffer size. Avoid
rewriting unchanged sizes when buffer changes notify the format listener.
Remove listeners before teardown, including failed initialization, so they
cannot configure a device that the AudioUnit has already released.
Add hardware-independent regression coverage for switching, rate changes,
scope filtering, limits, synchronous notifications, diagnostic overrides,
absent devices, and listener cleanup. Record the original gameplay evidence
and the additional silent Core Audio validation in the audio reference.
Validation: full host tests, Mac host build, docs checks, and the iOS source
compile check (178 files) passed. Silent USB/speaker switching and speaker
rates of 44.1/96/48 kHz verified 221/480/240 frames. HDMI switching and
gameplay listening after these listener changes remain unvalidated.

Profile 0100C1F0051B6000 (SDK 4.4.0, Retro Studios' engine, NVN): plays on the Mac from boot
through the menus and the intro cinematic into the first level at 60 fps. General changes:
- svc SetHeapSize: a request beyond the heap region returns ResultOutOfMemory, as Horizon
(the game binary-searches its heap size between 3 and 6 GB)
- shader_split.py: SNVN program records in Retro's RFRM forms (MaterialArchive.arc, the packs'
MTRL resources) and the LZSS-compressed startup material archive in main
- nvn_mtl.m: a texture in a CPU_UNCACHED pool starts with its storage at first use (title logo,
menu panels); transform feedback captures draws that rasterize too
- dmsh_build.py: transform feedback buffers holding several outputs (DK's fur simulation);
chain header regenerated
- hle_audren.c: the renderer event is the kernel event the audio service gives, not the SDK's
local one (the main thread was starved at the first level's load)
- hle_oe.c: oe::GetUserInactivityDetectionTimeExtensionMode
Profile 010057D006492000 (no virtual address memory: the 4 GB heap layout; tex_flush_upload and tex_dirty_upload for the textures Unreal writes from the CPU into uncached pools after creating them) and its note. Brought up on the Mac through the boot, the language notice, the title, the traveler selection and Ophilia's and H'aanit's openings (free play in the cathedral and in S'warkii) at 30 fps; battles, sound and the iPhone not yet tested.
General changes found on it:
- patch_nso.py: a jump table whose index is bounds-checked with a 64-bit cmp (main+0x1676f58), accepted only in the last pass so earlier rewrites are byte-identical.
- profile_guess.py: Unreal's 64 GB alias layout only with virtual address memory (this game sets a 3.08 GB heap instead).
- NVN: nvnTextureBuilderGetSparseTileLayout / nvnTextureGetSparseTileLayout (Unreal sizes a sparse texture's mip tail with it; unimplemented, it asked for 1.75 GB twice); sparse 2D textures without a packaged layout take the block height of their 64 KB tile (the world map's tiles were shuffled); every virtual pool gets an address range of its own until its first mapping decides between the alias (a whole-pool mapping, Mario's pool) and the sparse page table (Unreal's one-texture pools, mapped piece by piece: streamed textures were black and later mappings refused).
- Audio renderer: SdkMutexType is looked up only when the SDK uses it (SDK 3.5.1 takes LockMutex at +0x1f8).
README: the gallery entry (Mac screenshot of S'warkii, IPA ~3.6 GB, all 5,434 shaders built for iOS); AGENTS.md: seventy-one games.
Checked on the rebased tree: the tool tests (15 skipped), the docs tests, a Mac boot into the traveler selection; before the rebase the graphics tests (make run, exit 0).
DSP callers were charged the local SDK CPU server budget, whose command representation is larger than the Horizon service representation. For Age of Calamity the service requires 0x61d000 while the local SDK requires 0x760000, exhausting the fixed sound heap.
Calculate the service requirement through renderer revision 15 and supply larger local backend storage separately, with cleanup on failed open and after renderer close. Remove the two game heap cuts and add sizing, nested-open, failure and lifetime regression coverage.
Validation: 360 seeded cases match isolated Horizon machine-code execution across REV1-REV15; the original game heaps initialize all five players and produce audio; the host suite, documentation and patch checks, SDK 8/20 smoke checks and iOS C compilation pass. iOS runtime and long battles remain untested.
