How to connect Nebula Max, Firestick and soundbar?

Hi!

I would like to connect the nebula max with a firestick and a soundbar. Ideally through hdmi to have the best quality and no time gap with the sound. Is that possible? Do I need a hdmi spitter or does it not help me?

I thought I might connect the firestick with my splitter and the splitter with my max and the soundbar. Does it work? :woman_shrugging:

If I connect the soundbar through bluetooth I have a time gap…

Thank you!
