Hi @awava, thanks for using the dev forum.

I am not seeing anything related to the SDK in that stack trace. What leads you to believe that this is being caused by the SDK?

Thanks!

It was not specifically an issue within the Zoom SDK. Android 7 has a garbage collection issue when multiple AudioTracks are spun up and then closed.

I ended up finding a fix in Android 8 and back-porting the fix to Android 7.

Glad to hear you were able to resolve this, and thank you for confirming that it was not an SDK issue. 🙂
