Hello, I am trying to capture and record my android device’s microphone audio.
I am able to do to, with the audio capture component on my pawn. I ask for the permissions for recording and i can even get the audio from my device and sounds fine, the issue come up if i have to use “open level” after recording. i then get a crash. if i open level before recording everything is fine. but after recording i get a crash on open level.
here is my blueprint setup.
i tried this on my oculus quest 2 but the log did not return an error so i recreated the setup on my phone, one plus 8, and the save issue exists but at least the log has an actual error in it.
and here is the crash log from my device
MICAndroidTest.log (134.9 KB)
any help would be appreciated. thank you!

We had this exact same issue in 4.27.2 and unfortunately believe it is a bug in the engine, we have been able to fix it by patching the engine as follows:
At line 64 in the github link below, if(!InputOboeStream) should be changed to if(InputOboeStream) (exclamation point is gone).
https://github.com/EpicGames/UnrealEngine/blob/4.27.2-release/Engine/Source/Runtime/AudioCaptureImplementations/Android/AudioCaptureAndroid/Private/AudioCaptureAndroid.cpp#L64
To patch the engine, we followed the following guide Building Unreal Engine from Source | Unreal Engine Documentation .

I am having the same problem but in this case from the Editor itself, The origin of the problem is to have the tick marked “Automatic activation” this is happening in Unreal Engine 5.1, however it did not happen in Unreal Engine 5.0.3

Reported on github, they should fix it soon.https://github.com/EpicGames/UnrealEngine/pull/9950
You have 2 options, wait for the fix to be uploaded or compile unreal engine from the source code and change that line of code.

I hope there is a fix in 5.2, any idea on how to customize it to record the audio stream of the device ? I want to get the audio from the device and pipe it to a submix and create VFX using Niagara. How can I do that ?

The engine has some bugs related to the capture feature working on Android, as well as on Quest 2 and iOS for example, and these were fixed in RuntimeAudioImporter plugin:https://www.fab.com/listings/66e0d72e-982f-4d9e-aaaf-13a1d22efad1
It also automatically requests audio capture permissions.
Here’s documentation specifically about the capturable sound wave (which can capture audio from input devices): Capturable sound wave | Georgy Dev Docs
This bug has already been fixed
