Did you open your Audio Session before calling setAudioFocus() ? What are the parameters that you give to setAudioFocus() ?

Note : I plan to clean the Audio Focus handling very soon.

Yes, I opened the audio session. Any parameters in setAudioFocus cause the error, I am calling it like this:

await recorder.openAudioSession(
        focus: AudioFocus.doNotRequestFocus,
      );

//Later on in the code (causes error)
await recorder.setAudioFocus(
        focus: AudioFocus.requestFocusAndStopOthers,
        mode: SessionMode.modeVoiceChat,
        category: SessionCategory.playAndRecord,
      );

//Stop recording
await recorder.stopRecorder();
await recorder.setAudioFocus(focus: AudioFocus.abandonFocus); //causes error

It happens using the default constructor as well; recorder.setAudioFocus(). The same code works on iOS with no error

I am going to clean this f***ing Audio Focus handling. I will look to your issue. Please keep it open.

 await soundRecorder?.setAudioFocus(
          focus: AudioFocus.requestFocusAndStopOthers); // error on this line
