What

A new tests/AudioOut2SpeakerArray.cpp (registered after the AudioOut2 latency test) covers sceAudioOut2SpeakerArrayCreate and sceAudioOut2GetSpeakerArrayAmbisonicsCoefficients. Creation rejects a null handle or parameter block, 0 or 33 speakers, memory too small for the array and misaligned memory, without writing the handle, and otherwise places the array in the memory given. For four speakers on the horizontal plane at 0, 90, 180 and 270 degrees, the W channel splits 0.25 to each speaker, the first-order Y and X channels follow the sine and cosine of each azimuth (±0.25), and a second-order channel decodes to 0, as four speakers decode only the first order. A channel without the ambisonics flag, a sixth-order channel, a wrong coefficient count, null coefficients and memory holding no array are rejected.

Until now no test called it.

Changed: core/libs/prx/libSceAudioOut/CMakeLists.txt, core/libs/prx/libSceAudioOut/tests/AudioOut2SpeakerArray.cpp. Test only, no change to the library.

Tested

Linux (Ubuntu 26.04, GCC 15.2), Release: cmake --build build --target audio_out2_speaker_array_tests and ctest -R '^audio_out2_speaker_array$' --repeat until-fail:3 pass on this branch, which is current main plus the test. tools/check_conventions.py --base upstream/main passes.

Windows (run by maskym: Windows 11, i7-12700K, WinLibs GCC 15.2.0, Release, with other open PRs merged in): audio_out2_speaker_array passes (comment).

The four-speaker geometry exercises the expected SN3D W/Y/X values and the unsupported second-order zeroing for this implementation; the invalid flag/order/count/null-handle cases are also covered. I manually checked the overlap bot warning for #5021: its AudioOut CMake change only selects the SDL link dependency near the top of the file; it does not overlap this test registration hunk, so no dependency is needed. The author reports three passing Linux runs and conventions; hosted eligibility, conventions, intake, labels and report pass. Product jobs are skipped by path policy. I did not rerun the test locally.

Windows result for head 9773824265, merged into main 2ee8e9751a (the PR's Tested section names no Windows run).

Host: Windows 11 26300, Intel i7-12700K, WinLibs GCC 15.2.0 (x86_64-ucrt-posix-seh, r6), Release, BUILD_TESTING=ON, Ninja. Build clean.

The tree also carried the open PRs #11172, #10780, #10729, #11614, #10631, #10582, #11547, #11572, all merged cleanly, so the run is a joint one; the tests of this PR are audio_out2_speaker_array. Together with the whole libc, CesCs, Font, FreeType, LibreSsl3 and NpUniversalDataSystem suites those tests belong to: 160/160 passed, this PR's in 0.05 s; the AudioOut suite separately 21/21. Not run on a PS5.

AI-assisted: yes (Claude Code), the runs and the numbers above are from this machine.

@maskym thanks for the Windows run. I've added it to the Tested section.

Reviewed 9773824265879cfdfebb134fe7c1f5bb13f70f90 — approve. The speaker-array fixture checks rejected creation without writing a handle, placement in caller memory, known first-order coefficient values, unsupported channels/counts and null/invalid arrays. This is CPU coefficient validation; no audio device playback was performed.

Windows/GCC 15.3 Release native validation from pinned sources: head: 1 passed, 0 skipped; audio_out2_speaker_array; author base was source-compared: production sources are unchanged; its runtime was not built or executed for this review. This changes test coverage, not production behavior, so an old-production failure is not required. The build reuses matching dependency source pins and the existing FFmpeg package; no full product or game execution is claimed.
