Hi @robaghamalian
Welcome to the Sonos Community!
I am not permitted to recommend any third-party products as a Staff member, and have not tried to do this myself, so cannot recommend anything personally.
My replying here will get your thread back on the list of those most recently active, however, so perhaps someone who can recommend something will now see this thread and assist.
In theory, it should be possible. If you don’t use apps built into the projector to play content, it may be easier/cheaper to tap into the HDMI cable from the source device than to find an eARC compatible splitter.
I hope this helps.
Something like this should work. It doesn't have RCA audio out, but you can get a 3.5mm to RCA adapter to connect to the bass shakers.
Awesome! Thank you Pool-3015! I’ll order it and give it a try.
