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, > [@Turningz](#): > > 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. This is a known issue and there is a task to address it. Unfortunately, we don’t have a workaround at the moment. > [@Turningz](#): > > 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. 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. ---

Hi, We have just released a new update that resolves the issue of sounds being interrupted by alarms. Please update your FMOD version to the latest to see if the issue persists. For more information, you can also refer to this post: > [@鸿蒙系统下fmod声音被闹钟中断后没有恢复如何解决](https://qa.fmod.com/t/fmod/22108/7): > > 是的，我们昨天发布了新的更新，目前最新的 2.02.24 以及 2.03.03版本都已经修复了声音打断的问题。请注意比较稳定的 2.02.24 版本目前还需要点击 All 按钮才能显示出来： 不知声音延迟具体指的是哪方面呢？是所有声音播放出来的时候都有很明显的延迟么？还是说是UI按钮点击的时候有延迟呢？目前来说对声音延迟的解决方案还是只有我们之前在这个帖子里聊到的解决方法：[OpenHarmony平台 团结引擎 mixerSuspend/mixerResume 调用无效 - #7 by li\_fmod](https://qa.fmod.com/t/openharmony-mixersuspend-mixerresume/22045/7)
