Quick summary
Trueplay tuning keeps Sonos systems sounding balanced long after installation day. This checklist mirrors the protocol we follow on service visits: stabilize the network, confirm firmware, capture before-and-after measurements, and leave behind documentation anyone can reference.
Working methodically prevents rushed tune-ups that unravel the moment a sofa moves or a firmware update lands. Keep this guide nearby whenever you add rooms, remodel, or inherit a Sonos system that needs professional polish.
Pre-flight network and firmware checks
Start by validating the network. Confirm every stationary Sonos device is hardwired or has a strong Wi-Fi signal. Run latency and packet-loss tests from the rack and from remote rooms so you know calibration data will upload without hiccups.
Update the Sonos app and firmware, sign into the household account, and temporarily disable guest VLANs or isolation features that might block the tuning device. Charge the tablet or phone you will use for Trueplay and disable incoming call or notification alerts.
Check for background noise. Turn off HVAC blowers, refrigerators near open kitchens, or loud aquariums. Quiet environments let Trueplay capture the room accurately the first time.
Devices that benefit most from Trueplay
Atmos soundbars such as Sonos Arc, along with Arc + Sub + Era 300 surround packages, see dramatic improvements when tuned to the room. Architectural speakers powered by Sonos Amp also benefit, especially when ceiling height or wall materials would otherwise skew tonal balance.
Portable and bookshelf speakers—including Era 100, Era 300, Move 2, and Roam—tighten their bass response and midrange clarity after a quick pass. Make a roster of every speaker you plan to tune and note which ones will remain in dedicated locations versus those that travel.

Run Trueplay zone by zone
Run Trueplay with the iOS device that will remain on site for future touch-ups. Begin during a quiet time of day, disable nearby fans or dishwashers, and follow the on-screen prompts. Sweep the device slowly from waist height to ceiling height, pausing briefly in each quadrant of the room.
For symmetrical rooms, save the tuning profile and copy it to paired speakers so tonal balance stays consistent. In open-concept spaces, experiment with splitting oversized zones into logical groupings—kitchen, breakfast nook, living room—so the algorithm can adjust for distinct seating areas without overcompensating.
Document the process with screenshots or a short video so future caretakers understand the motion path and microphone positioning that produced the results.
Document names, volumes, and resets
After tuning, record each zone name, default volume, EQ adjustments, and any night-mode or loudness tweaks. Add these notes to the project binder alongside Wi-Fi credentials, rack elevations, and wiring diagrams.
Capture screenshots of the Sonos app showing speaker groupings, default services, and TV AutoPlay settings. Store them in a shared drive or password manager so anyone servicing the system can reproduce the configuration if a reset ever occurs.
If you manage multiple properties, maintain a simple change log that lists the date of tuning, the device used, and any anomalies noticed during calibration.
Keep the system sounding right
Schedule seasonal or post-renovation check-ins to re-run Trueplay after furniture moves, new rugs, or new shelving. Encourage homeowners or facility managers to call before rearranging large pieces so cable slack and brackets can be adjusted gracefully.
For high-use spaces, create calendar reminders every six months and pair them with a short punch list—firmware update, network check, Trueplay confirmation, documentation refresh.
