  (Android 9 AOSP at 1920×720, 160 dpi; the car build installs as the system user — checked).
+- 2026-10-31 — Sound check on the car (2.43.3), radio: `com.saicmotor.radio` playing, `isMusicActive` false, analyser enabled without error and silent for all 10 seconds (peak 0.00, -9600 mB). The audio analyser does not hear the radio. The owner ran Bluetooth and CarPlay too; those reports have not reached the server yet (the outbox sends oldest first and stops at the first failure, retrying while the service runs).
 - 2026-10-31 — App 2.43.3 published (`car-2.43.3`).
 - 2026-10-31 — Music checks from the car: the radio publishes a session while it plays (`com.saicmotor.radio`, 29 October, DAB: TITLE the station, ARTIST the programme text, AUTHOR the band), with `isMusicActive` false, so its sound may not pass through Android's mix and the audio analyser may not hear it. The sound check with the radio playing will tell. CarPlay playing (31 October, 2.43.2) has `isMusicActive` true, like Bluetooth on 28 October. The sound check itself has not run on the car yet: 2.43.3 was not published and those reports came from 2.43.2's music-sources check.
 - 2026-10-31 — App 2.43.3: **sound check** on the Logs tab (`SoundProbe`, `SoundLevels`), asked for before the Halloween pumpkin's light follows the music (owner: "make the light in the pumpkin react to the equalizer/sound of the music"). One tap: 10 seconds of levels from `Visualizer` on session 0 (peak, bass, mid, treble, rms), saved and sent like a recording; no sound kept, no microphone. New in the car build's manifest: RECORD_AUDIO and MODIFY_AUDIO_SETTINGS. Grounds for trying: Bluetooth played with `isMusicActive` true (28 October check), `libCarPlayPlatformAudio.so` uses AudioTrack and no direct PCM. Whether the analyser hears anything on the car is what this is to find out. Tested: unit tests, lint, emulator (silence says nothing was playing; a pulsing 110 Hz + 1 kHz test tone from another app is heard, peak 0.27–0.91, bass strongest, the tone kept playing, no prompt, no crash). Not tried on the car.
