If during the game, someone starts calling through instant messengers, for example Telegram, then when I return to the game, I get this error:
[FMOD] OutputCoreAudio::suspend : Cannot start audio unit. (err: 561015905).
[FMOD] System::mixerSuspend() returned ERR_OUTPUT_INIT for SYSTEM (0x136B14008)
The errors is reproduced only on iOS

Logs with stacktrace:

Hi,

Thank you for the information. Unfortunately, while playing a single event and getting a Discord call I was not able to reproduce the issue.

Do you have any custom background behaviors in Unity? Would it be possible to get a stripped-out version of the Unity project that is experiencing the issue uploaded to your profile? Note, you will have to register a project with us to be able to upload.

If not, could you elaborate on the set up of the project when the crash is occuring? Does it happen everytime?
