Why is no sound playing?

        return decoder;
    }


    private byte[] readBase64AsByteArray(String base64) {
        return Base64.decode(base64, Base64.DEFAULT);
    }

}

In general, I am making a plugin for ionic (capacitor), a base64 string containing aac arrives in play, after which it is decoded to pcm and played through AudioTrack. The problem is that MediaCodec.Callback()::onInputBufferAvailable is not called, or rather it is called occasionally, it is not clear under what conditions and throws an IllegalStateException, if called,
onOutputBufferAvailable is never called
