Use soundbar to stream video to Apple TV

Hello,

I have a projector with an Apple TV 4k connected.

My idea is: if I buy a soundbar with Airplay, having HDMI ports in, could I stream from the bluray player to the soundbar to the Apple TV with Airplay?

Something like:

• Bluray player ---- HDMI ---- Soundbar
• Soundbar ----- Airplay ---- Apple TV
• Apple TV ----- HDMI ----- Projector

Thank you!
