Sonos Says It's Playing But There's No Sound

Step one: is it actually playing? How to tell

Look at the progress bar, not the play button. The bar is advancing means audio really is streaming and the break is on the output side. The bar is frozen, or never moves past zero, means playback never started and the break is on the source side.

This is the highest-value step in the whole guide, because it halves everything that follows. Advancing → go to steps two and three (volume and room). Frozen → skip to step four (the source).

Step two: the volume is up — what am I missing?

A large share of "no sound" reports are a volume sitting at zero — and not on the control you assume. There are three layers, and you need to check each of them:

• Room volume — the individual room's level. Once rooms are grouped, the slider you reach for is usually the group volume, which moves each room proportionally. A room already sitting at zero stays at zero no matter how far you push it.
• Mute — muting is separate from volume. A muted product shows a solid green status light, which is the fastest way to confirm it.
• Volume limit — Sonos can cap each product individually. If a low cap was set for a child's room or for night use, the slider simply cannot get past it.

The most direct test: walk to the speaker and turn it up with the physical buttons on the unit. Those act on that one product and bypass all of the app's grouping logic.

Step three: could it be playing in a different room?

The music may genuinely be playing — just not where you are standing. Three common versions of this:

• The room picker at the top of the app is still on whichever room you used last. Walk to that room — you will usually hear it immediately.
• You previously AirPlayed to a different destination — another room, or an Apple TV — and your iPhone is still holding that choice.
• There are two systems in the house — an S1 and an S2 side by side, for instance — and the app you have open is controlling the other one.

Step four: the progress bar is frozen — what does that mean?

If the progress bar was frozen in step one, this is almost certainly the layer. The test is blunt: play something from a completely different source.

Try an internet radio station, or a track from your local music library. If radio plays and your streaming service does not, you have narrowed it to that service — usually an expired authorisation, fixed by removing and re-adding the service in the app, with nothing wrong with the speaker. Only if nothing plays should you go back to suspecting the hardware.

Line-in and TV are two separate paths of their own. For line-in, confirm the cable is seated and the source device is genuinely playing. For TV, confirm the television's audio output is actually routed to the port your Sonos is on — HDMI ARC/eARC or optical — rather than having fallen back to the TV's own speakers.

Extra cases for home theatre and stereo pairs

Paired products redistribute channels, so "no sound" can really mean "not from the one you expected". If the main unit is silent while the surrounds play, or the reverse, the problem is in the pairing rather than in any single product — separate them and pair again, and it usually comes back.

Also, in a home theatre setup music and TV audio travel different paths. If TV audio is missing while music plays fine, the thing to check is the television's audio output settings — leave the Sonos alone.

Still silent after all that — should I factory reset?

By now you know it is "nothing plays" rather than "one service does not play", and you have ruled out volume and room. Do not jump to a factory reset here. Submit a diagnostic from the app first — it gives you a confirmation number, and with that number Sonos support can read the device-side logs that you cannot.

The two-minute version

If you would rather not read the whole thing, run these in order. Each takes seconds and each gives you an immediate yes or no:

• 1. Is the progress bar moving? This decides which half you investigate.
• 2. Turn it up with the buttons on the unit — this bypasses the app and all grouping logic.
• 3. Check for a solid green status light — solid green means muted, and that is the whole answer.
• 4. Play an internet radio station — if that works, you have confirmed it is the music service.
• 5. Power-cycle that one speaker — it deletes nothing and clears a fair share of stuck streams.

Two things not to start with

One: a factory reset. It permanently deletes registration information, your My Sonos favourites and your connected services — and it would not have fixed most of the cases above anyway, because volume, room and service authorisation are not among the things it wipes. Keep it as a last step, and ideally only once you have confirmed the product's own configuration is what is broken.

Two: rebooting everything in the house at once. It sometimes works, but it costs you every clue: you never learn which layer failed, so when it happens again you start from nothing. Working through one product at a time at least leaves you with an answer.
