Cheap options to add multiroom setup for my two soundbars?
I have an LG SH5 soundbar that only has Bluetooth capabilities. It's connected to my TV that has a Google TV Streamer (also got an Apple TV but currently only used as a hub).
On my desktop setup, I have a Polk MagniFi Mini soundbar which has more capabilities such as Airplay 2, casting etc.
I need to make the LG soundbar smart, preferably for as little as possible. I want to have a multiroom setup between these two soundbars if possible. Synced audio, but I dont mind if the audio has slight delay because it's for music only.
I have a vinyl record player that has both RCA analog outputs and Bluetooth capabilities. My dream is to be able to somehow play records from this to both soundbars synced and also be able to play music on them from Spotify using Spotify Connect.
What would be the best way of achieving this setup? Not sure if it's even relevant at all, but I use a Home Assistant Green for the rest of my smart home setup (lighting, sensors etc.)
