【openharmony platform】app muted after system alarm

FMOD Studio
1

Hello,
we found that when migrating our project to the Huawei HarmonyOS platform, we encountered an issue: after the system alarm or incoming call ringtone ends, the application itself is completely muted. I observed that FMOD threw the following two log messages, and I want to confirm whether the application being muted is a result of FMOD’s internal handling of system callbacks, or if the system itself is muting the application. If it’s the former, then I can only wait for FMOD to release a new version to fix this issue. If it’s the latter, then perhaps we can attempt to address the problem using native code on the HarmonyOS platform.

OHAudio_Renderer_OnInterruptEvent : Interruption event has occurred, type: 0, hint: 2.
OHAudio_Renderer_OnInterruptEvent : Interruption event has occurred, type: 1, hint: 1.

many thanks

Hi,

This is a known issue and there is a task to address it. Unfortunately, we don’t have a workaround at the moment.

It is a result of FMOD’s internal handling of system callbacks.

Thank you for bringing this to our attention, I will let you know once there’s a workaround or update regarding the issue.
