synapse sound linking with govee

So I have the Govee rbgic gaming lights and can’t get them to sync through synapse so wanted to see if anyone had insight.  Setup is Xbox x with steelseries wireless gac headset running synapse off windows ten laptop.  I can get the lights to pair with the synapse app so it’s not a connectivity issue.  I have the govee controller plugged in to the gac by 3.5mm in the line out.  Line out on gac is set to speakers although doesn’t make a difference if I switch it to streaming sound.  I’ve even tried the line in.  Only other thing I can think of trying is optical sound off tv but I don’t even know if they make an adapter to convert that to 3.5mm.  Pretty much have wasted a bunch of time trying to get it to work and sound is not my forte at all
