I have a flutter iOS app that has some simple sound FX for button clicks, swipes, etc.

In simulator and on real device the sound works fine, but when i upload the app to testflight (and App store) the sound FX don't play. When I upload the app to my phone via xcode I am using the release profile so I don't see what the difference could be.

I have also gone through the archive that i uploaded and verified that the sound files are indeed there.

I have other flutter apps that use sound but non since the iOS 26 update. I've tried 3 different flutter sound libraries and all face the same issue.

Wondering if anyone else is seeing this issue or if I'm missing a simple permission or something that has changed recently?

Thanks in advanced

Thanks for the post.

Upon uploading your app to TestFlight and installing it from there, all audio on your app appears to be disabled?

Are you utilizing Flutter? Have you reached out to the support channel for Flutter, the third-party resource you are using?

I do not believe this issue is related to TestFlight, as other apps have audio. However, if you can reproduce the issue using Xcode by creating a focused sample and uploading it to TestFlight to verify the presence of audio, that would be helpful.

A focused Xcode project that builds and demonstrates the issue. Ideally this will be a new Xcode project created specifically to demonstrate this issue, and which includes only the minimal code and API necessary to reproduce the issue. This focuses on the important code paths and may require you to perform additional debugging to extract the relevant code. Please do not include any 3rd-party code or frameworks unless they are absolutely required for this targeted sample project to run.
