As I see room.setSpeakerOn is ignored and it does not use the speaker, but by setting the default room options its working, can you confirm this behavior?

    roomOptions: RoomOptions(
      enableVisualizer: true,
      defaultAudioOutputOptions: AudioOutputOptions(speakerOn: true),
    ),

@petodavid , fixed in this PR.

When I enter the room, I don't need to sound, I embed Unity to play the audio. Here's how I set it up:

final result = await liveChatRepository.joinRoom(
config: tokenConfig! , autoSubscribe: false, enableAudio: false);


@override
void enableMedia({bool?  enableAudio, bool?  enableVideo}) {
if (enableAudio ! = null) {
currentRoom? .localParticipant? .setMicrophoneEnabled(enableAudio);
currentRoom? .setSpeakerOn(true, forceSpeakerOutput: true);
}

if (enableVideo ! = null) {
currentRoom? .localParticipant? .setCameraEnabled(enableVideo);
}
}


newRoom = Room(
      roomOptions: RoomOptions(
        adaptiveStream: true,
        dynacast: true,
        enableVisualizer: true,
        defaultAudioPublishOptions: const AudioPublishOptions(
          name: 'eve_audio_track_name',
          audioBitrate: AudioPreset.musicHighQualityStereo,
        ),
        defaultAudioOutputOptions: const AudioOutputOptions(
          speakerOn: true,
        ),
   

I set it up here, too. No
I can use the speaker to play sound normally, but when I turn off the microphone, if the sound is playing at this time, the sound of the speaker suddenly becomes very small:
I set the speaker on here but it doesn't work, if I turn on the microphone and it works again. May I ask where I set the wrong, how to modify, thank you

I solved the problem and I found that:
When autoSubscribe=true, the audio system works because:
LiveKit keeps the audio system active
Even if the microphone is turned off, there is still a subscribed remote track to keep the audio system active
When we set autoSubscribe=false and cancel all subscriptions:
The audio system has no active track
As a result, the system may enter the low-power state, and the sound of the speaker becomes smaller.
You need to set
// Disable track playback, but keep the subscription status

track.disable();

This will allow you to use the speaker normally
