[BUG] Extreme playback volume after using volume boost #1051

Describe the bug

Music suddenly started playing at an extremely high volume, even when the Samsung media volume was set to zero. Adjusting the volume using the phone's volume buttons did not resolve the issue.

I had previously enabled the volume boost setting at +1 dB. After resetting the boost to 0 dB, playback returned to normal.

To Reproduce

I haven't confirmed a reliable reproduction sequence, but the issue occurred after using the volume boost setting.

1. Use Gramophone with volume boost set to +1 dB.
2. Play a local music file.
3. Observe the playback volume and attempt to lower it using the system media volume controls.

Note: I could not reliably reproduce the issue after resetting the boost to 0 dB.

Expected behavior

Music volume should follow Android's media volume controls. A +1 dB boost should not cause extremely loud playback or make the volume controls ineffective.

Smartphone

• Device: Samsung Galaxy S22+ (SM-S906U)
• Android version: Android 14 (SDK 34)
• App: Gramophone
• App version: 1.1.2
• Build: 31bc800 (Release-play)

Additional context

• The issue occurred on October 17, 2026.
• Restarting the phone and clearing Gramophone's cache did not resolve the problem.
• The issue was resolved after resetting the volume boost setting to 0 dB.
• I captured diagnostic logs containing audio-volume traces and audio-track cleanup warnings, which I can attach if needed.
• The issue has not been confirmed to reproduce after the setting was reset.
