What XGIMI Horizon Ultra No Sound Usually Means
If your XGIMI Horizon Ultra has video but no sound, the problem is usually tied to audio output settings, HDMI handshakes, Bluetooth routing, or source-device configuration.
This guide walks through the most common causes and the fixes that solve them fastest.
Because the Horizon Ultra runs Android TV and supports multiple audio paths, a single wrong setting can silence the whole system even when the projector appears to work normally.
The good news is that most cases are reversible without factory resetting the projector.
Common Causes of XGIMI Horizon Ultra No Sound
Before changing settings blindly, it helps to understand where the audio signal can break.
The issue may originate from the projector itself, the connected device, the cable, or the playback app.
- Muted or low volume: The projector, remote, app, or source device may be muted.
- Wrong audio output: Sound may be routed to Bluetooth speakers, a soundbar, or HDMI ARC instead of the internal speakers.
- HDMI handshake issue: External devices can fail to negotiate audio correctly.
- App-specific audio bug: Streaming apps sometimes lose audio after updates or login changes.
- Format mismatch: Dolby Digital, Dolby Atmos, or other passthrough formats may not match the connected device.
- Faulty cable or adapter: A damaged HDMI cable or USB-C adapter can carry video but not stable audio.
Check the Basics First
Start with the simplest items, because they account for a large share of no-sound reports.
These checks take less than two minutes and often solve the problem immediately.
Verify volume and mute status
- Use the remote to raise the volume on the projector.
- Check whether the playback app has its own mute control.
- Confirm the source device, such as a Roku, Fire TV Stick, laptop, or game console, is not muted.
Test another app or input
Play audio from a different app, then switch to another HDMI input if available.
If sound works elsewhere, the issue is likely limited to one source or one app.
Restart the projector and source
Power off the XGIMI Horizon Ultra, unplug it for 30 seconds, then restart the source device.
A clean restart can re-establish HDMI audio communication.
Review the Audio Output Settings on XGIMI Horizon Ultra
The Horizon Ultra can send audio through its internal speakers, Bluetooth devices, or HDMI-connected audio equipment.
A mismatched output setting is one of the most common reasons for XGIMI Horizon Ultra no sound complaints.
- Open the projector settings menu.
- Go to the sound or audio section.
- Confirm the output is set to the intended device.
- If Bluetooth audio is enabled, disconnect it temporarily and retest the internal speakers.
If the projector was previously paired with wireless headphones, soundbars, or speakers, it may still be routing audio there even when those devices are off.
Forgetting the Bluetooth device and pairing again can resolve this.
Fix HDMI Audio Problems
HDMI devices are a frequent source of audio issues because they must exchange both video and audio capability information during setup.
When that exchange fails, you may get picture without sound.
Try a different HDMI port
Move the cable to another input on the projector or on any HDMI switch in the chain.
A single port or switch can be the weak point.
Replace the HDMI cable
Use a known-good high-speed HDMI cable, especially for 4K content.
A cable that carries video poorly may also interrupt audio stability.
Check the source device audio format
On devices like Apple TV, PlayStation, Xbox, Fire TV, or Windows PCs, set audio output to stereo, PCM, or Auto if passthrough is causing trouble.
Some receivers and sound systems handle Dolby formats differently.
Disable audio passthrough temporarily
If you are sending sound to a soundbar or AV receiver, test with internal speakers first.
This helps determine whether the issue is with the projector or the external audio chain.
Bluetooth and External Audio Device Issues
Bluetooth is convenient, but it is also a common reason users think the projector has no sound.
If the Horizon Ultra is paired with a Bluetooth speaker, all audio may be redirected there.
- Turn off nearby Bluetooth speakers and headphones.
- Open paired devices and disconnect wireless audio accessories.
- Reboot both the projector and the external speaker.
- Re-pair the device only after confirming the projector outputs audio normally.
Latency and connection drops can also make Bluetooth audio seem broken.
If audio cuts out often, test the built-in speakers or a wired audio setup to confirm whether the wireless link is the cause.
Check the App, Streaming Service, and DRM Settings
Sometimes the projector is fine, but the app is not.
Streaming services may fail after cache corruption, account changes, or content protection issues.
- Force close the app and reopen it.
- Clear the app cache and test again.
- Sign out and back into the service if needed.
- Update the app through Google Play if an update is available.
Services such as Netflix, Disney+, Prime Video, and YouTube can behave differently depending on device certification, HDMI mode, and audio format.
If one app has no audio while others do, the issue is likely app-specific rather than a projector fault.
Adjust Advanced Sound Settings
The XGIMI Horizon Ultra may expose audio options that affect how sound is decoded or routed.
These settings matter most when the projector is connected to a soundbar, AV receiver, or gaming console.
Try PCM or stereo output
If available on the source device, switch the audio format to PCM or stereo.
This is often the most compatible option for troubleshooting.
Disable surround sound temporarily
Turn off Dolby Atmos, Dolby Digital Plus, or other surround modes to see whether a simpler audio format restores playback.
Reset sound preferences
Some Android TV builds retain audio preferences that interfere with new devices.
Resetting the sound settings can clear incompatible routing choices without erasing all data.
When the Built-In Speakers Work But HDMI Does Not
If the internal speakers work but an HDMI source has no sound, the projector itself is probably not defective.
The problem is more likely in the HDMI device, cable, adapter, or audio format.
In this case, test the source on another display, such as a TV or monitor with speakers.
If the source also has no audio elsewhere, focus on that device’s sound settings.
If it works elsewhere, return to the Horizon Ultra’s HDMI settings and cable chain.
When to Reset the Projector
A factory reset should be a last resort, but it can help if settings have become inconsistent after multiple device changes or software updates.
Use it only after you have tested cables, inputs, Bluetooth, and audio settings.
- Back up any important app logins or preferences.
- Perform a system reset from the settings menu.
- Reconnect devices one at a time and test audio after each step.
Reintroducing devices one by one makes it easier to spot the exact source of the problem if the no-sound issue returns.
Signs the Problem May Be Hardware-Related
Most XGIMI Horizon Ultra no sound cases are software or setup related, but hardware faults can happen.
Watch for these warning signs:
- No sound from internal speakers in every app and input.
- Audio cuts out with volume changes or slight cable movement.
- Crackling, distortion, or intermittent channel loss.
- Bluetooth audio fails across multiple devices.
If those symptoms persist after a reset and cable replacement, contact XGIMI support or an authorized service provider for diagnosis.
Quick Troubleshooting Checklist
- Confirm volume is up and mute is off.
- Test a different app or HDMI input.
- Restart the projector and source device.
- Disconnect Bluetooth speakers or headphones.
- Replace the HDMI cable.
- Change the source audio format to PCM or stereo.
- Clear app cache or reinstall the app.
- Reset sound settings if needed.
Using this sequence usually identifies whether the XGIMI Horizon Ultra no sound issue comes from the projector, the source, or the audio chain attached to it.
