Sound distorted when dropped to background.

Android Version(s): 10
Android Device(s): Samsung galaxy 7, Samsung Galaxy M10
Oboe Version: 1.3

**Short Description**
Sound becomes "darth vader like" if app drops to background.

**Steps To Reproduce**
Create streams in/out with 1 channel. Start it and after mechanism was successfully started drop app to background.

**Expected behavior**
Normal sound like it was before.

**Actual behavior**
Sound becomes distorted.

**Additional context**
I found that system changes channels to stereo it causes distortion. And my fix was simply init with 2 channel and reduce channels to mono.

I remember that problem was in android 8.0.
