What

Adds one entry to the libSceAudioOut technical debt: sceAudioOutSetVolume reads one volume per flagged channel from the array, stores it as given with no range check and returns 0, which is an assumption and not measured on hardware. shadPS4 and fpPS4 (both PS4) read only the first value, use it for every flagged channel and return SCE_AUDIO_OUT_ERROR_INVALID_VOLUME when it is above 32768 (0 dB), while KytyPS5 (PS5) reads one value per channel and checks no range. The entry does not say which is right and no code or test changes.

Tested

Documentation only. tools/check_conventions.py --base upstream/main passes. Based on main 73f4f7e06e, and it merges with main 474030e584 without a conflict (checked 2026-10-31 16:55 UTC). I read the three emulators at the commits named in the entry (KytyPS5 5e837a9beac82c031868eaad9348d6a48245fb99, shadPS4 0614ce324be092791b758d79f93d9f1ca5b10a81, fpPS4 04cefd43e6fddd1ab033e7980cd356d14c964905) and our sceAudioOutSetVolume in AudioOut.cpp.

Overlap

Checked on 2026-10-31 at 13:54 UTC against main 73f4f7e (1632 open pull requests). I took the changed files of each open pull request from git diff --name-only against its merge base. Ten of them change docs/dev/debt/libSceAudioOut.md: #13913, #13885, #13836, #13781, #13694, #13676, #12863, #12791, #12765 and #5021. git merge-tree against that main: this head alone merges cleanly, and so do its pairs with #13913, #13885, #13836, #13781, #13694, #13676, #12791 and #12765. The pairs with #12863 and #5021 conflict, but each of them conflicts with main on its own. #13885, #13676 and #12765 are my own pull requests on the same file; they merge cleanly with this one in either order, so none has to go first. Checked once more on 2026-10-31 at 16:55 UTC against main 474030e584: of the 63 pull requests opened since 13:45 UTC, #13988, #13989 and #13998 change these files, and each merges the same with and without this change.

Reviewed — looks good

The new debt entry accurately distinguishes AnyPS5’s unmeasured behavior from the three emulator references and does not present emulator behavior as a console measurement.

What I ran

Reviewed head ea4e14638f928502bd9a44d796d18520fbdfe640 against main at 474030e58424fefdb65e5df9f3820810fbb4553c; the current-base merge preview is clean. Environment: Linux x86_64, Python 3.11.2, GCC 12.2.0. Documentation only; no build or compilation was applicable.

I also compared the added description with sceAudioOutSetVolume in AnyPS5 and the emulator implementations at the pinned commits named in the debt entry.

Results

Check	Result
Diff check	Passed; no output.
Conventions and PR template	Passed locally and in hosted CI.
Current-base merge preview	Clean.
Source comparison	The cited implementations match the entry: shadPS4/fpPS4 reuse the first value and reject values above 32768; KytyPS5 reads per-channel values without that range check. AnyPS5 also reads per-channel values and returns success without a range check.
Hosted CI	Intake, eligibility, conventions, and labels passed. Build and platform jobs were skipped.
