Monitor Off does not mute live WASAPI output in beta #665
Description
Activity
Root cause confirmed in installed beta
beta-2026-09-26-0eb6fb2: liveaudioMixSessionreportsmonitorEnabled=true,monitorStatus=playing, but nomonitorControlstate;/stateshows empty authority epoch/revision 0. The #661 coordinator cannot submit an Off command without this token. The native code emitted the token in idle branches but not the live branch.PR #666 adds that missing live field and a test for On → Off → On while a PCM source keeps the mix live. Targeted native tests and all 2248 MediaCore .NET tests pass. Installed fixed-beta acceptance remains; the active meeting was not interrupted to swap binaries.
Patched unsigned beta published from main
975076b8: https://github.com/iamfatness/CoreVideoPro/releases/tag/beta-2026-09-26-975076b . All six assets and GitHub SHA-256 digests verified; CI green.The previous beta remains installed and running in the owner's meeting. Keep this issue open until the new beta is installed and Off/On is confirmed on GoXLR Game with live audio. The local installer smoke gate was not run because it refuses to alter the existing CoreVideo shortcut/installation.
Installed acceptance passed on
beta-2026-09-26-975076b(main975076b8). The installed manifest verified 849 delivered file hashes with zero mismatches; runtime probe exited 0 (success=true,windowOpened=false); both stable shortcuts target the new install.In the installed app, Control API
audio.monitor.setOff returnedok=trueand live native state changed tomonitorOn=false, revision 3, last resultapplied,monitorStatus=muted. On returnedok=true, revision 4,monitorStatus=playing. The live snapshot containsmonitorControl, with Zoom Live and 10 participants. Monitor frames advanced from 781,440 to 925,440 over 3 seconds with zero underruns. The owner independently confirmed: "Button works again." The initial monitor On state was restored after the test.The standalone installer stress script still self-refused on an existing CoreVideo shortcut; this does not negate the actual installed release and live monitor acceptance. Closing #665.

Symptom
In beta
beta-2026-09-26-0eb6fb2, the Monitor UI toggles On/Off but GoXLR Game keeps playing audio in a live meeting.Evidence
The installed native process and local Release binary hash match (
26319C...39B7A89). Live/snapshotreportsaudioMixSession.monitorEnabled=true,monitorStatus=playing, but nomonitorControl;/statereports empty monitor authority epoch and revision 0.MediaCore::audioMixSessionState()includesmonitorControlin idle branches but omits it in the live branch. The #661 shell coordinator needs the authority epoch/revision before it submits a versioned edit, so the visible Off draft cannot apply while the mix is live.Done when
