Sound problems with Android for YouTube

i’am new with streaming and used yesterday for the first time ManyCam on my Android Smartphone (Huawei P30 Pro - Android Version 10) for a Livestream to YouTube. But the Sound is not clear.

I’ve tried it with my iPad Air and all works fine. When i use my iPad as primary device and add the Android Smartphone as an additional cam, then the sound is perfect.

Here is my livestream from yesterday with the soundproblems.

In this case my Android Smartphone was the primary Device and ipad as an additional cam.

I’ve also tried only my Smartphone and direct streaming to youtube with a StreamKey. Nothing helps Reducing the resolution didn’t help either.:frowning:

Maybe someone here can help me, to find my mistake.
Thank you.
