Sonos port to Beoplay A9 4th Gen

I need detailed guidance how to connect Sonos Port to Beoplay A9 4th gen so that it can play along in sync with the Sonos system of speakers I have (Era 300, Arc). So far I was able to connect the Port to the Sonos system and connected the Port to the B&O A9 using an RCA to 3.5 mm cable (A9 has only 3.5 mm in). No sound whatsoever coming out of A9. I used the line out ports of the Port to plug the RCA. I am doing something wrong apparently as for now only the Sonos speakers are playing the online radio stations, not the A9. Guidance needed

Make sure the Line-Out Level in the Sonos app is set to "Fixed" instead of "Variable" (under Settings > System > Sonos Port). Also, check that the Beoplay A9 is set to the correct input source. If it's still not working, try a different RCA to 3.5mm adapter to rule out a cable issue.

    Thanks, the A9 was not set to line-in input source, that resolved the issue.
