Direct answer
For the Sonos Roam 2 speaker, microphone/mute, button mapping, account link, permissions and service status should be separated. First, test a local button/volume command and inspect mute.
What this covers
- Sonos Roam 2 speaker (Roam 2)
- Sonos product; Wi-Fi/Ethernet, Bluetooth, voice, home-theater and line-in capabilities vary.
- The specific fault this record addresses: voice assistant or controls are not working
What it does not cover
- ×The same symptom on a different Sonos product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
The microphone is muted
What separates it No response at all to the wake word, with a mute indicator lit.
How to confirm Most devices have a physical mute, and it is the first thing to check because it produces total silence with no other symptom.
- 2
The device is not connected to the network
What separates it The device lights up in response but then reports an error or says nothing.
How to confirm Visible response means the wake word was heard, which moves the problem to the network or the service.
- 3
The assistant was never set up or has been signed out
What separates it The device responds that it needs setup, or requests sign-in.
How to confirm Voice assistants are configured through the companion app and can be signed out by an account change.
- 4
Background noise or music is masking the wake word
What separates it Poor recognition while playing loudly.
How to confirm Devices duck their own output to listen, but loud playback and room noise both reduce recognition genuinely.
- 5
The device is placed where it cannot hear
What separates it Poor recognition tied to position — in a cabinet, against a wall, or behind furniture.
How to confirm Far-field microphones need reasonably direct line of sight to the room.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- Whether the device visibly responds to the wake word — a visible response means the microphone works and moves the problem to the network or account.
- Whether a microphone mute indicator is lit.
- Where the device is placed relative to the room.
- Whether the assistant was set up in the companion app.
Check for a physical microphone mute
ReversibleIt produces total silence with no other symptom, and it is easy to press accidentally.
Note whether the device lights up in response to the wake word
ReversibleA visible response proves the microphone works, which moves the problem to the network or the account.
Confirm the device is on the network and the assistant is signed in
ReversibleAssistants are configured in the companion app and can be signed out by an account change.
Move the device away from walls, corners and cabinets
ReversibleFar-field microphones need reasonably direct access to the room.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- Roam 2. Sonos product; Wi-Fi/Ethernet, Bluetooth, voice, home-theater and line-in capabilities vary.
- Type — ultraportable battery speaker (WiFi + BT)
- The smallest, most portable Sonos — battery-powered, works on WiFi at home and Bluetooth away, waterproof. Both battery symptoms and Sonos WiFi symptoms apply; its small size means shorter runtime than a Move by design.
- WiFi vs Bluetooth
- On WiFi it is a full Sonos speaker (app/grouping); on Bluetooth it is a standalone portable. The Roam 2 (unlike the original) has a dedicated Bluetooth button for easier switching.
- Charging
- Charges by USB-C or an optional wireless charger; if it starts low, it is not being charged fully between uses.
- Power path
- Internal or removable battery. Every capability that costs current — night vision, higher stream quality, longer recordings, frequent events — is paid for in runtime, so a change in behaviour after a settings change is usually a power consequence rather than a fault. Cold weather reduces usable capacity sharply.
- Symptom boundary
- This record covers Sonos Roam 2 speaker when it voice assistant or controls are not working. A different symptom on the same hardware, or this symptom on a different Sonos product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !Review which account a voice assistant is signed into before troubleshooting further if the device was bought second-hand or inherited — it may still be linked to someone else.
Evidence ledger
Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. Sonos publishes this as "Alexa commands not working on Sonos". Sonos' article for a voice assistant that is set up but not responding. Probed 2026-08-21: title-verified. What that article does not carry is the model boundary — it is written for a product line, and Roam 2 is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
My Sonos Roam 2 keeps switching between WiFi and Bluetooth.+
The Roam moves between your WiFi (at home) and Bluetooth (away), and it can flip if the WiFi signal is weak where you are using it. Use the dedicated Bluetooth button to lock it to Bluetooth when away from a strong network, and keep it in WiFi range at home for full Sonos features. If it drops off WiFi at home, that is a network/signal issue for that spot rather than a speaker fault.
My speaker ignores the wake word completely.+
Check the physical microphone mute first — it silences the assistant entirely with no other symptom and is easy to press by accident. If the device does light up when you say the wake word but then does nothing useful, the microphone is fine and the problem is the network connection or the account it is signed into.
Does this answer apply to every Sonos model?+
No. It is scoped to Roam 2. Sonos product; Wi-Fi/Ethernet, Bluetooth, voice, home-theater and line-in capabilities vary.
What should I record before troubleshooting voice assistant or controls?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing voice assistant, controls. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Do not share passwords or private voice history.
