Rive plays unrelated sound

Description

My app plays sounds when user performs certain actions (button clicks etc) and has Rive animations with sound. iOS build has a strange issue: last app sound (which is unrelated to Rive) is played after minimizing-maximizing the app.

I'm able to reproduce it only on iOS and only when running on a physical device (issue is present in both debug and release builds).

Rive file has an embedded sound and audioplayers package is used to play other sounds.

I suspect this could be related to how both rive and audioplayers play audio in the native layer.

Steps To Reproduce

Example app with the issue:

Archive.zip

Steps to reproduce the behavior:

1. In the test app tap the button to play 'button click' sound
2. Play the Rive animation using 'play' button
3. Minimize the app
4. Maximize the app
5. 'Button click' sound is played after app is maximized and without user's action

Source .riv/.rev file

test_riv_rev.zip

Expected behavior

No sound is played after app is maximized

Device & Versions (please complete the following information)

• Flutter Rive version: ^0.14.0-dev.8
• Device: iPhone 12 Mini, iPhone 14 (not reproducible on iOS simulator)
• OS: iOS 18.6, iOS 26
• Flutter Version:

Start with the provided Archive.zip and test_riv_rev.zip, then reproduce on a physical iOS device using the listed Flutter and Rive versions. Compare the embedded Rive sound with the audioplayers button sound across minimize and maximize; done means maximizing the app does not replay the unrelated button-click sound.
