Problem Description
If TV sound is missing, the HDMI ARC/eARC settings or TV audio output may be wrong. This guide checks TV audio settings and reconnects the Beam.
Why This Happens in Real Homes
If TV sound is missing, the HDMI ARC/eARC settings or TV audio output may be wrong. This guide checks TV audio settings and reconnects the Beam. In day-to-day use, this usually looks like No sound from TV; Music plays in Sonos app; TV speakers off.
Most cases trace back to TV audio output set incorrectly; ARC/eARC disabled; HDMI cable not seated. The fix works best when you go step by step instead of changing multiple settings at once.
A practical order for this issue is: Check TV Audio Output -> Enable ARC/eARC -> Reseat HDMI -> Run Sonos Setup. After each step, test the exact behavior that was failing so you can confirm what actually solved it.
