What is true of this model and changes how you fix it
- Official specifications5 Class-D amps, 1 center tweeter, 4 elliptical midwoofers, 3 passive radiators (no up-firing drivers — confirms the virtual-Atmos design). Dimensions 25.63 x 2.68 x 3.94in, weight 6.35lbs — much smaller than the Arc's 44.96in width.
- Type — compact soundbar (WiFi + HDMI eARC)A compact soundbar with virtual Dolby Atmos (no up-firing drivers — it simulates height), connecting by HDMI eARC and WiFi. 'No TV sound' is the eARC/HDMI-CEC link; streaming/grouping is WiFi/app.
- WiFi-firstControlled via the Sonos app over WiFi; a missing speaker is usually a network issue.
- Virtual AtmosIts Atmos is virtualised through its drivers, so the height effect is subtler than the Arc's dedicated up-firing speakers — that is the design, not a fault.
- Virtual AtmosIt has no up-firing drivers, so its Dolby Atmos is virtual: it simulates height through processing. The overhead effect is subtler than the Arc's dedicated height speakers by design.
- Wi-Fi firstThe Beam is controlled through the Sonos app over Wi-Fi, and a speaker that is missing from the app is usually a network issue.
- MultiroomSonos groups speakers into rooms over the home network. A room that will not group or plays out of time is usually a network or setup matter.
- PlacementA compact bar sits under a TV; its sound is shaped by the room, and a wired connection to the router makes grouping more reliable.

Exact questions
Questions that only have an answer for the Sonos Beam (Gen 2)
My Sonos Beam Atmos doesn't sound as 'tall' as expected.+
The Beam creates Dolby Atmos virtually — it has no dedicated up-firing height drivers like the Arc, so it simulates the height effect through processing. The overhead sense is therefore subtler by design, not a fault. Make sure the TV is passing Atmos (Dolby Atmos should show in the Sonos app during Atmos content) and the room is set up in the app. For stronger height effects, the Arc has real up-firing drivers.
