Recommendations on how to integrate firestick (hdmi input) to formation duo/audio

Im not very tech savvy but trying to learn, here is my problem…any advice appreciated :wink:

My current setup is B & W formation duo with formation audio. The formation audio is fed via sky box (optical) and works well for tv audio. However, im looking to integrate my firestick (hdmi). So basically looking for recommendations for an av receiver with roon that can accept hdmi’s, has hdmi out, and stream audio to the formation duo?
