can xbox play dolby audio through inbuilt music apps(apple music etc)?

Most music is stereo and so will play in stereo only

Spatial audio requires the dolby atmos app to be purchased to enable the codec.

Settings > General > Volume & audio output > Advanced. and turn bitstream on

Not sure about apple music; however, if that happens on Spotify I just have to unpause the music while on the app I'm playing and the music will resume.

Hi James,

I read through your thread and personally I believe the issue relates to the first two bullet points you mentioned with the background music apps audio and the audio from the game are essentially competing to produce the sound over HDMI Stereo Uncompressed.
Your test using the headset with Windows Sonic selected also leads me to believe the snapped music apps audio is interfering with the game audio and vice versa since Windows Sonic for headphones is a spatial audio technology like Dolby Atmos for headphones.
It also improves the accuracy of the sound you hear in your games.

Snapped apps was a big thing a few years back but Microsoft removed it due to the issues associated with the feature. Background music apps are essentially an extension of snapped apps because they operate while you are playing games so bugs like this one
may be due to snapped apps not being generally supported anymore.

Have you tried your music apps without snapping them and playing them normally without playing a game in the background?

If I am playing music from the native XBOX Groove app, the music will keep playing to my stereo even if I turn my TV off.

But not so if I am streaming the music from Apple TV into XBOX HDMI in. Music stops when TV goes off.

Thanks

500GB+ HDD. (Or make them easy to swap). Backwards compatability. Better inbuilt music player. More video codecs recognised. (and audio ones).
