oblgny,
Why are you saying that the vault has to be connected to the internet to play?
Why are you saying that your computer has to be on for the vault to play?
After reading about it, the vault acts as a NAS and has internal storage. You should be able to play files stored in the vault device without internet nor computer. If you have another NAS(e.g. Mycloud, Synology, etc.) connected to your router, any files stored there should be accessible by the Bluesound app and played without computer nor internet.
Yes, you need internet to play streaming content (e.g. Tidal, Quobuz). If you have Bluesound app on a wireless device(e.g. tablet or phone) can't you control the vault wirelessly without a computer? Reviews seem to say that you can.
Sorry, if I misunderstand, but it sounds like you are inadvertently making statements that kill Bluesound's lack of functionality and probably aren't true. With best intentions, Cheers,
Spencer
