How to connect an iPad Pro 12.9 to Bose Lyfestyle 535 (latest series)?

Hi,

 

I'd like to connect my  iPad Pro 12.9 to Lifestyle 535 to watch streaming/movie from computer in order to enjoy great quality sound & large screen. I would like to have a WIRE CONNECTION (not wiresles).

 

In the Setup menu, "Add new device" I do not see iPad. It used to work with "Degital Media Player" but I just changed TV and it does not work anymore. What would be describe it? I have an HDMI cable connected to an adaptor HMDI/lightning cable (official adaptor from Apple store).

 

Thanks in advance for your help!
