How Do I Set Up the Sonos Ray Soundbar?
- Connected via HDMI (Ray uses optical only)
- Optical cable not seated / wrong port
- TV optical output not enabled/format wrong
Problem Description
You are setting up the Sonos Ray soundbar with your TV. Connect the Ray to your TV using the included optical audio cable — the Ray uses an optical connection (not HDMI). The optical port is on the back of the Ray. Your TV must have an optical audio output. This guide covers the optical connection, TV audio output settings, and Sonos app configuration.
Why This Happens in Real Homes
The key fact about the Sonos Ray: it connects to your TV by optical (TOSLINK), not HDMI — so there's no ARC/CEC. That changes setup and volume control versus other Sonos bars. Plug the optical cable into the TV's optical audio output, and set that output to PCM or Dolby Digital.
Add the Ray to your network in the Sonos app, turn off the TV's built-in speakers, and set up remote/volume control (it learns your TV remote's IR volume commands in the app). No sound is usually the TV's optical output disabled or set to a format the Ray can't take; there's no HDMI on the Ray by design.
Symptoms
- Ray will not connect to TV
- No TV audio
- Optical vs HDMI question
- TV volume not controlled
- Will not connect to WiFi
- Setup stalls
- Lip-sync
- Weak signal
Recognize these? Here's what usually causes it.
Common Causes
- Connected via HDMI (Ray uses optical only)
- Optical cable not seated / wrong port
- TV optical output not enabled/format wrong
- TV audio still on its own speakers
- On the wrong network
- IR remote not set up for volume
- AP isolation
- Firmware pending
Most fixes happen in the first 3 steps.
Smart speakers are always listening for the wake word when unmuted. Review and delete your voice history regularly in the app privacy settings. Never place the speaker in bathrooms or near water sources as moisture can permanently damage internal components.
Step-by-Step Solution
Connect the Ray to your TV
The Sonos Ray connects via an optical (TOSLINK) cable — not HDMI. Plug the included optical cable into the TV optical audio output and the other end into the Ray. The optical port is on the back of the Ray alongside the Ethernet port and power input. If your TV does not have an optical output (some newer thin TVs removed it), you need an HDMI audio extractor to convert HDMI ARC to optical. The Ray does not have an HDMI port.
Set your TV audio output to optical
Go to your TV sound settings and set the audio output to Optical or External Speaker. On some TVs, you also need to set the optical audio format to PCM or Dolby Digital — the Ray supports Dolby Digital 5.1 but not Dolby Atmos. If the format is set to Auto or Bitstream and you get no sound, switch to PCM first to confirm the connection works, then try Dolby Digital for surround sound.
Set up in the Sonos app
Plug in the Ray power cable and open the Sonos app. Tap Settings > System > Add Product. The app discovers the Ray and walks you through setup including WiFi connection, room naming, and TV audio configuration. After setup, run Trueplay to calibrate the soundbar for your room — this significantly improves clarity and bass response. The Ray is designed for small to medium rooms up to about 200 square feet.
Configure TV remote control
The Ray does not come with a remote — it uses your TV remote for volume and mute via the optical connection and IR sensor. In the Sonos app, run the TV remote setup to teach the Ray your TV remote commands. Point your TV remote at the Ray and press volume up when prompted. The Ray learns the IR codes and responds to your existing remote. If your TV remote uses Bluetooth instead of IR (some LG and Samsung remotes), use the Sonos app for volume control.
Add surround speakers and a sub
The Ray supports a 5.1 surround setup. Add a pair of Sonos One, Era 100, or One SL speakers as surrounds through the Sonos app — go to the Ray room and select Add Surrounds. Add a Sonos Sub for deep bass. The Ray handles center, left, and right channels while the surrounds handle rear effects. This transforms the Ray from a basic soundbar into a capable surround system for a smaller room.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
Place your speaker in a central location at ear height for best voice pickup. Avoid corners and bookshelves which muffle the microphones. If you have multiple speakers, set up multi-room audio groups so music plays in sync across rooms.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
