Android (Drag & Drop) audio stops after 39 plays (Thunkable Live + exported APK)

In Drag & Drop projects on Android, audio playback stops completely after exactly 39 sound plays. After this point, no further sounds will play until the app is restarted.

  • Platform: Android

  • Affected: Thunkable Live app (Android), exported Android builds (APK/AAB)

  • Not affected: iOS, Web preview

  • Builder: Drag & Drop (DnD)

  • Not reproducible in: Snap to Place (STP)

To reproduce:

  1. Open this minimal test project:
    https://x.thunkable.com/copy/5d3e2610a6c416070b8655cc9d1172b8

  2. Run on Android (Thunkable Live or exported build)

  3. Tap the button repeatedly

Each tap:

  • Increments a counter

  • Plays a sound

Observe the sound behavior at 40 taps

Expected Result:
Audio should continue playing indefinitely on each button press.

Actual Result:

  • After 39 plays, audio stops entirely

  • No further sounds will play

  • App remains otherwise functional

  • Only restarting the app restores audio

Impact:
High. Prevents use of sound effects/music in any moderately interactive app (e.g. games/music apps), severely limiting functionality.

Workarounds Tried:

  • Rebuilding in Snap to Place (works, but not viable for existing DnD projects)

  • No known workaround within Drag & Drop

Additional Context:
This issue has persisted for a considerable time. The suggested workaround (rebuilding in STP) is not practical for existing projects, and there is currently no way to convert DnD → STP.

Thanks for the bug report and the MVP project. I’ve made a bug report to our engineering team. I’ll update this thread when there is new information on this.

Thanks @brianl
