SoundSend has no sound: identify the symptom and next check

Start by identifying what is silent and which transmitter you have. Check playback, the selected input and the speaker test sound before changing settings. Allow about 5–10 minutes for the first checks.

Before you change anything

Keep your Wi-Fi setup and take screenshots of the current speaker layout and audio settings. Start with the branch that matches your symptom.

Start with the right transmitter

This guide covers the WiSA SoundSend transmitter with compatible WiSA speakers, including Lithe Pro Series speakers fitted with the WiSA bolt-on module. A Wi-Fi connection alone does not identify a WiSA-ready speaker.

Cinema Hub or another transmitter? Use the separate Cinema Hub checks below. For another brand of WiSA hub, use that model’s instructions; SoundSend app controls and button actions do not transfer to every transmitter.

Illustrative SoundSend setup with silent speakers. The TV volume of 30 is an example, not a recommended setting; crossed-out speaker symbols illustrate no audio, not a setting to select. Solid line: TV audio connection. Dashed line: WiSA connection path, not confirmation of playback. Product positions are examples.

Which symptom matches yours?

1. SoundSend: all speakers are silent

  1. Check playback and volume. Play a programme you know has sound. Check mute and raise the volume gently using the TV remote or SoundSend app.
  2. Match the input to the cable. For HDMI, check the TV end is in the socket labelled ARC or eARC, and select HDMI ARC/eARC as the SoundSend input. If you use optical, select Optical instead.
  3. Check the TV output. Select HDMI Receiver, HDMI Out or the equivalent ARC/eARC option. For HDMI use, check CEC is enabled. Menu names vary by TV; use your TV’s manual for the exact labels.
  4. Test the speakers separately from the programme. In the SoundSend control app, open the speaker map or MyZone and use each speaker’s chime/test control. Note which speakers sound and whether their channel positions are correct.

If all test chimes work but TV audio does not: focus next on the TV/source path. Try another programme or a built-in TV app and note the result. Chimes working helps narrow the check; it does not prove every part of the system is fault-free.

If speakers are missing or do not chime: go to the next section before making more TV changes.

Reconnect the TV’s HDMI ARC/eARC connection

If every speaker plays its test chime but TV audio remains silent over HDMI, try the connection order in WiSA’s CEC and ARC/eARC best-practice guide. Skip this check for optical.

  1. Photograph your settings. Check that TV CEC and HDMI ARC/eARC audio output are enabled, with eARC enabled if supported.
  2. Power off the TV and SoundSend fully using their normal accessible power connections. Reconnect the HDMI cable between the TV’s ARC/eARC socket and SoundSend while both devices are off.
  3. Turn on the TV first, then restore power to SoundSend. Replay the programme at a comfortable volume.

If sound returns, check the original programme and expected channels. Stop if playback stays reliable. Otherwise, record the result for support. Keep speaker pairings and Wi-Fi configuration in place; this is a connection check, not a factory reset or proof of a particular fault.

Check the audio format without losing your starting point

Photograph the current settings first, then change one setting at a time. WiSA’s SoundSend TV setup guide recommends Pass-through or Auto for normal output, with TV-specific alternatives. SoundSend does not decode DTS: if your source is sending DTS, select an available supported audio track or output format.

PCM is a comparison test, not a universal fix. Some TVs reduce output to stereo when PCM is selected, so surround channels or Atmos may be lost. If you compare PCM with your original setting, record whether sound returns and restore the original setting afterwards unless you deliberately choose that trade-off. Tell support the result.

When sound returns, replay the original programme and check the channels you expect. Stop here if playback remains reliable; there is no need to reset the speakers.

2. SoundSend: a speaker is missing

Take a screenshot of the speaker map before changing anything. Confirm the exact speaker model and, for Pro Series, whether the WiSA module is fitted. Ask your installer if you are unsure; you do not need to remove a ceiling speaker for this check.

  1. Check power and wake the speaker. Make sure the affected speaker is powered on and is not left in standby. Try playing music to that speaker using its normal, already configured music source at a comfortable volume. Alternatively, switch its power off and back on using the normal accessible power control. Allow it to start, then check whether it appears in the SoundSend speaker map. If music plays over Wi-Fi, stop that music before testing TV audio; Wi-Fi playback alone does not confirm a WiSA connection.
  2. If it is still missing, put the speaker into WiSA pairing mode. Use the pairing or associate-mode instructions for your exact speaker model. For Pro Series, the WiSA bolt-on module must already be fitted. Pairing is different from a factory reset: do not use a long reset-button hold or erase your Wi-Fi setup. If you cannot identify the correct pairing control or reach it normally, ask your installer or support for help.
  3. Then scan from SoundSend. In the SoundSend app, select Scan for Speakers if available. After discovery, check the speaker’s channel position and play its test chime.

Stop when the speaker appears and its test chime works in the correct position, then retry the original TV programme. If it remains missing, record which of these checks you tried and what happened.

Expected result: the speaker appears in the map and plays its test chime in the correct position. If it remains missing, send support the map and model details before another reset. Keep your existing Wi-Fi configuration in place.

3. SoundSend: one speaker is silent or drops out

Use the speaker map’s chime/test control for the affected speaker and compare it with one that works. Record whether the speaker stays listed and whether the problem occurs during a film, after changing inputs or when the audio format changes.

If it chimes but loses programme audio, and your TV has separate eARC On and Auto settings, you can compare Auto with On. Note the original setting and restore it if there is no improvement. This is a test, not a diagnosis of the speaker or TV.

See Single Speaker Dropouts in SoundSend System. If it does not chime or disappears, use the missing-speaker checks above.

4. SoundSend: sound starts late

If sound begins after a wait and then plays normally, record how long it takes from switching on the TV to hearing audio. Repeat once with the same source and programme. Also note whether changing input starts the delay again.

The SoundSend startup-speed guide covers TV settings to compare. Its PCM recommendation is a startup test with the format trade-offs explained above. Change one setting at a time and keep the results; there is no guaranteed startup time for every TV.

5. Sound plays, but speech and picture do not match

This is lip-sync, rather than a wait for sound to begin. Tell support whether the sound is ahead of or behind the picture, which app or source is affected, and whether it continues after playback has settled. Avoid changing speaker distances just to investigate a startup delay: record the two symptoms separately.

Cinema Hub: use its own controls

The Lithe Cinema Hub has a remote, an on-screen display and multiple inputs. Use these checks instead of SoundSend app or button instructions.

  1. Match the selected input to the source. For TV return audio, the Hub’s eARC output connects to the TV’s ARC/eARC socket; select eARC on the Hub and ARC/eARC audio output on the TV. The Cinema Hub manual specifies TV digital output as Bitstream or Automatic and CEC enabled where available. For a player connected directly to a Hub HDMI input, select that HDMI input; select the matching Optical or LINE input for those connections.
  2. Inspect the speaker layout. Select the TV HDMI input connected to the Hub, then press OK on the Hub remote to open the on-screen display. Under Speaker setup → Speaker layout, check the layout and listen to the assigned-channel pings. Note any missing or wrongly assigned speaker before changing it.
  3. Separate streaming from speaker audio. Note whether TV audio, direct HDMI playback and network streaming fail in the same way. Being visible in AirPlay or Google Home does not establish that every WiSA speaker is connected.

If the problem continues, keep the network configuration and send the results to support. Use the Cinema Hub help hub and Cinema Hub manual page for this model. Do not apply SoundSend reset timings to the Hub.

Still need a hand?

Before another reset, gather:

  • The transmitter model, speaker models and WiSA module details, plus the TV model.
  • A simple connection list: TV ARC/eARC or optical, any external player, and any intermediary device.
  • App and firmware versions shown in the controls; screenshots of the speaker map/layout and current audio settings.
  • The exact symptom, affected channels, chime/ping results, source or programme, and startup timing where relevant.
  • What you changed, what happened and whether the problem returned. If music works over Wi-Fi but TV sound fails, include both results.

There is no need to send Wi-Fi passwords. These results help support choose the next model-specific check without repeating your setup.
