If your Bose Soundbar 700 suddenly has no sound, the cause is usually a simple connection, input, or settings problem rather than hardware failure.
This guide walks through the most common reasons and the fixes that restore audio quickly.
What the Bose Soundbar 700 no sound problem usually means
When a Bose Soundbar 700 powers on but produces no audio, the issue can come from the TV, HDMI ARC, optical audio, Bluetooth pairing, firmware, or internal settings.
In many cases, the bar is working, but it is not receiving or decoding the audio signal correctly.
The goal is to isolate whether the problem is with the soundbar, the source device, or the connection path.
That process is faster if you test one variable at a time.
Check the basics first
Before changing advanced settings, confirm the simple things that often cause a Bose Soundbar 700 no sound complaint.
- Make sure the soundbar is powered on and not muted.
- Increase volume using both the remote and the soundbar controls.
- Verify the TV is not muted or set to an extremely low volume.
- Confirm the correct input source is selected in the Bose Music app or on the remote.
- Look for any visible status lights that may indicate a connection or setup issue.
If the soundbar responds to volume changes but remains silent, the issue is likely upstream in the input or TV audio output settings.
Is HDMI ARC or eARC causing the issue?
HDMI ARC and eARC are common reasons for no sound because they rely on both devices negotiating audio properly.
A loose cable, incorrect TV port, or disabled ARC setting can stop audio entirely.
Try these HDMI ARC checks
- Use the HDMI port labeled ARC or eARC on the TV.
- Reconnect the HDMI cable on both ends.
- Replace the cable if it is damaged or not high speed.
- Enable HDMI-CEC and ARC/eARC in the TV settings.
- Power off the TV and soundbar, unplug both for 60 seconds, then restart them.
Many Bose Soundbar 700 owners find that a full power reset restores the handshake between the television and the soundbar.
Could the TV audio settings be the real problem?
TV audio output settings often determine whether the Bose Soundbar 700 receives usable sound.
Some TVs default to internal speakers, while others send an incompatible format.
Set the TV output correctly
- Choose external speakers, audio system, or HDMI ARC as the output.
- Disable TV speakers if that option conflicts with the soundbar.
- Set digital audio output to PCM if Dolby Digital causes silence.
- Turn off auto volume, night mode, or sound enhancement features temporarily.
PCM is a useful test setting because it is widely supported.
If audio returns in PCM mode, the issue may be a codec compatibility problem rather than a broken soundbar.
What if the source device is silent?
Sometimes the Bose Soundbar 700 is not the source of the problem at all.
A streaming box, game console, cable box, or Blu-ray player may be sending no audio signal.
Test another source
- Switch from HDMI to Bluetooth or optical if available.
- Try a different app, channel, or video source.
- Restart the streaming device or set-top box.
- Confirm the source device is not paused, muted, or set to the wrong audio format.
If one device works and another does not, the soundbar is likely fine and the issue is limited to that specific source or its audio settings.
How Bluetooth problems can lead to Bose Soundbar 700 no sound
Bluetooth is convenient, but pairing errors can produce a Bose Soundbar 700 no sound situation even when the devices appear connected.
A phone or tablet may show the soundbar as paired while sending audio elsewhere.
Fix Bluetooth playback
- Disconnect the soundbar from the phone and reconnect it.
- Remove the Bose Soundbar 700 from the Bluetooth list and pair it again.
- Turn Bluetooth off and back on on the source device.
- Make sure audio is not being routed to earbuds, headphones, or another speaker.
- Test with a different phone or tablet.
Bluetooth interference, weak signal strength, or stale pairing data can all interrupt playback without any obvious error message.
Is the Bose Music app configuration involved?
The Bose Music app can help manage settings, but it can also preserve old configurations that interfere with sound.
If the soundbar was previously used with another TV or source, stale settings may remain active.
Review app-based settings
- Confirm the correct product is selected in the Bose Music app.
- Check for software updates for the soundbar.
- Review input selection and source priorities.
- Remove and re-add the soundbar if the app is not responding correctly.
App issues are especially worth checking if the soundbar worked earlier and stopped after a network change, reset, or firmware update.
Could firmware or software glitches be blocking audio?
Like many smart audio devices, the Bose Soundbar 700 depends on firmware to manage HDMI, Bluetooth, and internal processing.
A buggy update or interrupted install can lead to no sound.
What to do next
- Check for Bose firmware updates through the Bose Music app.
- Restart the soundbar and the router if updates are pending.
- Allow enough time for updates to complete fully.
- If the system behaves oddly after an update, perform a reboot before assuming hardware failure.
Firmware problems are less common than connection issues, but they are important when the soundbar stops working after a recent software change.
When should you reset the soundbar?
A reset can clear temporary faults that prevent audio output.
It is a practical step when basic troubleshooting does not help.
Use a restart before a factory reset
- Unplug the soundbar from power.
- Wait at least 60 seconds.
- Reconnect power and retest audio.
If the problem continues, consider a factory reset only after you have tried cables, TV settings, and another source.
A factory reset will erase custom settings and pairing data, so it is best used as a final troubleshooting step before service.
When does hardware failure become likely?
True hardware failure is less common, but it becomes more likely if the Bose Soundbar 700 has no sound across every input and every source.
If HDMI, optical, Bluetooth, and app-based playback all fail after resets, the internal audio processing or amplifier may be involved.
Warning signs include repeated shutdowns, no response from buttons, unusual status lights, or persistent failure after a clean factory reset.
At that stage, Bose support or an authorized service provider is the best next step.
Fast troubleshooting order to follow
If you want the fastest path to solving Bose Soundbar 700 no sound, use this sequence:
- Check power, volume, mute, and source selection.
- Restart the TV and soundbar.
- Inspect and reseat the HDMI ARC cable.
- Change the TV audio output to PCM.
- Test a second source device.
- Re-pair Bluetooth if wireless audio is affected.
- Update firmware in the Bose Music app.
- Perform a reset if the problem remains.
This method helps separate device-specific issues from system-wide failures and avoids unnecessary resets.
Common mistakes to avoid
Several small mistakes can make the Bose Soundbar 700 no sound issue harder to diagnose.
- Using the wrong HDMI port on the TV.
- Leaving the TV set to internal speakers.
- Assuming a Bluetooth connection means audio is actually playing through the soundbar.
- Ignoring audio codec compatibility on streaming devices.
- Replacing the soundbar before testing another cable or source.
Careful checking is usually enough to resolve the issue without repair.
