[BUG]: I have an error playing sound

[BmcDev123]

Here is my audio code:

• This code is used to initialize the player:
  /// Khoi tao player
  Future initPlayer() async {
  // Mo player
  try {
  // player!.setVolume(1.0);
  opus = Opus();
  await opus.initOpus();
  player = FlutterSoundPlayer();
  await player!.openPlayer();
  await player!.startPlayerFromStream(
  codec: Codec.pcm16,
  numChannels: CHANNEL_1,
  sampleRate: SAMPLE_RATE_16000,
  bufferSize: 48000);
  if (AppTcp.flagTempCall == 2) {
  ApiSound().setSpeakerMode();
  } else {
  ApiSound().setReceiverMode();
  }

  } catch (e) {
  AppLogger.error("Error init player in udp remote ${e.toString()}");
  }
  }

• This code is used to play sound:
  await player!.feedFromStream(dataLast);

• This is my error in the log:
  F/libc (23504): Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x0 in tid 23685 (Thread-9), pid 23504 (com.bmc.viva_v2)

It seems that you have somewhere a reference to a not initialized variable.
