I would love the ability to play my own music in the background while watching videos. With some sort of volume mixer. Just a suggestion.
You can always play mp3 with winamp then open DeoVR and play your video.
But of course you are using quest 2, right?
Get a boombox, play some loud music, then put your quest 2 headset on. Easy fix.
I'm not sure if there is a technical possibility to implement such functionality.
I think this is not necessary for most of people
It's hard to imagine video work, for example, when watching YouTube, and playing music on one phone...
