   Carlos kindly added useful cross-platform differences between Windows and   
   Linux but I'm not sure about the platform differences for macOS which maybe   
   "Your Name" or "Nick Charles" can help us all benefit from their knowledge.

   The behavior Carlos purposefully helpfully points out is not seen on my   
   Windows desktop, so it may be a Linux-only seat-control behavior, or not.   
      
   What about macOS?   
      
   Maybe "Your Name" or "Nick Charles" can edify us as to how macOS behaves?   
      
   As far as I can recall from using Apple PCs in the past while I was   
   teaching at the local high school, macOS keeps audio output active   
   as long as:   
    a. our user session is the one currently logged in   
    b. the system is not put to sleep   
    c. the app (e.g., VLC) is allowed to run in the background   
   Where, from what I recall from my teaching days, locking the screen on   
   macOS or letting the display turn off does not revoke audio access. VLC,   
   Music.app, browsers & other players continue outputting sound normally.   
      
   This matches Windows behavior almost exactly as I recall, but not Linux.   
   Maybe "Nick Charles" or "Your Name" can help us understand why this is so?   
      
   If I can helpfully posit a reason why macOS does not work like Linux does,   
   it's perhaps on  macOS there is only a single active-user-session model.   
    a. On macOS, only one user session is active at a time   
    b. Where that session always retains control of the audio device   
    c. So switching users logs out or suspends the previous session   
      
   Since I no longer have an Apple PC to test this on, I ask "Your Name"   
   and/or "Nick Charles" to help us all confirm how macOS works with audio.   
      
   If they don't know more than we do, then what stands as the likely answer   
   of how macOS differs is that on macOS there is no concept of "seat   
   ownership", much as with Windows, but not like Carlos warned for Linux.   
      
   Your Name or Nick Charles,   
    On macOS, while playing audio in the background with VLC (or Music.app),   
    does switching to a TTY or another graphical user cause audio to pause   
    or go silent?   
      
   I suspect it will but it's always good to confirm with the Apple experts.
