Hello,

using MA on the Oculus Quest here. Game has got a number of songs.

I closely followed the tutorial:
www.dtdevtools.com/docs/masteraudio/HowToCreateAddressableSFX.htm

I am using the following MA API to play the addressable song at a future time, both because I need to sync some game-things with the music, and also to have enough time to load the clip and hence to be sure of when the clip will really start playing:

finishingSong = currentSong;
currentSong = MasterAudio.PlaySound(trackId, delaySoundTime: currentSongWillStartTime - Time.realtimeSinceStartup);

if (currentSong != null && currentSong.SoundScheduled)

currentSong.ActingVariation.SoundFinished += OnCurrentSongFinished;
else
Debug.LogError("Could not schedule next song: " + trackId);

I keep a reference of the previous PlaySoundResult in the "finishingSong" variable in case I will need to interrupt it: it is correct, yes?

How can I ensure that the sound starts playing when expected? (in my case, as from the code above, at currentSongWillStartTime)
Should I load the addressable manually in advance?
Also, I will not need the last sound after it finished playing. Should I unload it manually?
Can you show me some code to achieve the above?
Or does MA do it all automatically because I am using the delaySoundTime option?

Also, how should I best import the clip? should I use "streaming" for songs? I am currently importing as "decompress on load":
I am also using "load in background" and "preload audio data".
What are the best best option for addressable songs kind of sounds to play in MA ?

As the documentation mentions, you will want to load any Asset Bundle(s) that contain the Addressables beforehand to avoid very long delays as they are downloaded. I would do this in a separate Scene usually.

You don't need to keep a reference to "finishingSong". Whenever a scheduled clip is cancelled or stopped, it will release the Addressable if there are 0 instances of it playing.

Load in background I never use, but that depends on whether it's a clip that would be played at the very beginning of the Scene or not. I would avoid streaming except for at most 1 clip at a time, preferably in Playlist Controller (which is meant for music), not Sound Groups - which is for sound effects. However it it's an addressable clip, I'm not sure any of those settings matter as it's probably loaded into memory anyway (you might want to ask on the Unity audio forum). I'd do normal: preload audio clip, no streaming, no load in background. Also compressed audio is orders or magnitude slower than wav / ogg files (it may cause a slow frame as it starts to play).

Let me know if that answers all of your questions or not.
