Turn Table to have audio output for whole floor
Goal: Have my turn table have audio connected to wireless speakers across the whole first floor of my house (max distance ~100ft).
My stereo attached to the turn table can provide optical audio output and I have an Airport Express and was thinking of getting a Homepod + Homepod Mini to place around my house. However, I can't seem to find a way to get the optical output of my record player to an airplay input for these speakers.
Is there some sort of converter or device that could connect with my optical audio output and convert it to something wireless speakers like Homepods could play?
Flow :
record player -> stereo -> optical output -> [fill in device/transmitter] -> airplay -> homepod speakers
