Using FMOD v2.03.07.
The app works fine with normal usage, even when sending the app to the background and back to the foreground many times, everything works.
The issue is that if the app is sent to the background, and accessed many hours later (approximately 7 hours), any previously playing audio tracks are no longer audible, and new audio does not play at all. The CPU usage also spikes, causing stuttering animations in the app, perhaps due to the following data spamming the logs continuously, until the app is shut down/restarted:

Has anyone come across this issue before? Is there anything that needs to be done to prevent this from happening?

Hi,
Thank you for sharing the version number and log output.
Unfortunately, I was not able to reproduce the issue on my end. Would it be possible to upload the project or a minmal repro to your [FMOD Profile](https://fmod.com/profile#uploads), so I can take a closer look?

I won’t be able to upload the actual project, so I’ll create a minimal test project that, hopefully, reproduces the problem.

A project has been uploaded to my profile, filename “audiotest.zip”. I tried running this on an Android device for a few days, and could not replicate the problem, so I’m a little confused as to what could be causing the audio issue in the main project.
The audiotest project uses the [Axmol](https://github.com/axmolengine/axmol) game engine, which is a fork of the Cocos2d-x v4 game engine. If you wish to build the project, then instructions on setting it up are in the zip file. All relevant FMOD binaries are in there, and the project will work on Windows and Android. It may also build for iOS, but I haven’t tested that.
