Have been reading threads about switches but nothing quite fit the bill with my needs. So, here goes:

TV and Playbar mounted on wall with power (x2), single HDMI 4K (2.2)lead, Ethernet (x2) and optical going into wall about four feet and coming out near plug sockets. The reason I tell you this is because I do not want a load of wires trailing across wall.

I have HDMI 2.2 lead and optical connected to Sky Q with HDMI going to TV and optical going to Playbar. TV optical is only 2.0 output so did not want that connecting to Playbar.

I have recently bought an Amazon Fire Stick 4K however, since there is only 1 2.2 HDMI input into TV, I have to keep unplugging Sky Q to plug in Fire stick. Also, the Fire stick sound only comes out of TV speakers which sound rubbish compared to Playbar with Play 1s as surround. As well as that, the fire stick needs power (USB from TV not powerful enough apparently so wires have to run across wall via extension plug.)

I have looked into other threads which talk about the Octava HD41. I could set that up with Sky Q input 1 and Fire stick input 2. If I spent that much money, would the Fire stick plug into that with the sound coming out of the optical?

Thanks for any help in this. I hope it made sense because, frankly, I got a bit confused typing it!!!
