I’ve a simple sub-level blueprint see screenshot attached that adds a media sound component and opens a media player. This lets me project a video onto a 360 sphere. I can hear the audio in simulate mode but when I package the project no audio is played.
In case it’s a local video file media resource: did you copy the video file into the “Movies” folder in your Content Browser? For proper packaging, your mp4 files need to be copied into a folder that must be named “Movies”.
If your video content does play correctly and only sound is failing, I might be wrong with that. Just my 2ct
Fixed by adding ambience audio in the scene, disabled auto-play and added that audio source on the level blueprint.
Also for 3D sound make sure audio is .wav and MONO, and on the ambience audio details make sure you override standard settings by selecting attenuate and spatialize.
If you want audio that media player is playing when you playing the game(not editor)
You have to create a empty actor BP then create a "Media audio"asset in this BP,pick a MediaPlayer eg.“My MediaPlayer” you created,when you set a logic “play” “My MediaPlayer”,you will hear it’s audio in game(not editor)
