Hi, I have a Beam set up and working through ARC on LG TV - set up a new Sub (3) today and while it’s connected (solid white light) and linked to the Beam in the same room - no noise is coming out.

Have installed and deleted a few times, reset router a few times - not sure what it could be - any help would be appreciated! Diagnostic code 542593696 - thanks!

Hi @mickea,

Welcome to the Sonos community. Thanks for reaching out to us about your concern and letting us know what you have done so far to check why there’s no audio on the Sub.

Upon checking the diagnostic, no cloud connection was detected on your Sonos Sub. You can try the following steps if the Sub will improve.

  1. Remove Sub
    • Open the Sonos app for iOS or Android.
    • From the Settings tab, tap System.
    • Under Products, tap the room you would like to remove the Sub from.
    • Tap Remove Sub.
  2. Add Sub to another Sonos speaker
    • Choose Room for Sub: Removes the Sub from the current room and adds it to a different room of your choice.
    • Observe your Sub performance.

If there’s still no audio coming from your Sub, I recommend contacting our phone support to perform in-depth troubleshooting or possible product replacement. Please feel free to reach out in the future if you have any other questions.
