Describe the bug A clear and concise description of what the bug is.

Code: https://github.com/Canardoux/tau/blob/master/flutter_sound/example/lib/streamLoop/stream_loop.dart

Works fine at the beginning. But when playing audio data with another package (eg just_audio), and then want to use the stream loop again, the app crashes.

Reproduce:

Install Example, add just_audio, use the stream loop, stop stream loop, play audio via just_audio, start stream_loop => crash

I think that the other audio package overrides some configuration (Float32, channels) - so maybe it can be fixed with setting up these correctly again when initializing the package?

Hi @t-kietzmann ,

I cannot reproduce the bug on the future Tau Sound V9.0 . I am not aware to have fixed anything in this area, so it is possible that the bug still exists, but not in my configuration test.

Tau Sound V9 is not ready for a release. Even beta. There is a new API which is not stable and I did not wrote the documentation.

Of course, you can do some tests if you are courageous but it will not be easy without documentation. The source of the V9 fork is on github, and there is a submodule : tau_native. My test app is here

The plugin name is “tau_sound” (and not “flutter_sound”) The two classes are “TauPlayer” and “TauRecorder”. Also, be aware that tau_sound is under the GPL license and not anymore LGPL.

Hi @t-kietzmann ,

You are right. I get the same error when I follow your steps. There is something wrong somewhere. I am going to debug that. Thank you for your Problem Report
