Hi there,

I noticed asserts when playing audio: `buffer == NULL`

As long as I play local files only, no crashes occur. But if I stream audio 
using an unstable network connection (cellular data), the App starts crashing 
from time to time.

Update vom 3.0.1 to 5.0.2 did not help.

The asserts can be reproduced - example with android emulator:

```
