Fixing No Sound Issue on FireStick
Here are some simple and effective ways to troubleshoot and fix the no sound problem on your FireStick. It’s best to try each solution to identify the root cause.
Solution 1: Adjust Surround Sound Settings
A common cause of no audio on FireStick is a mismatch in the Surround Sound settings between your FireStick and your speaker system. Older speakers may not handle surround sound formats properly, leading to muffled or no sound at all.
To fix this, you may need to change or reset your surround sound configuration:
- Go to Settings on your FireStick.
- Select Display & Sound.
- Choose Audio.
- Click on Surround Sound.
- Switch the current setting to Best Available or try cycling through options like Dolby Digital Plus and Dolby Digital until sound returns.
Solution 2: Adjust Audio-Video Sync (AV Sync)
If changing surround sound settings doesn’t help and you notice a delay between video and audio, the AV Sync might be out of alignment.
Here’s how to fix it:
- Open Settings on your FireStick.
- Go to Display & Sound.
- Select Audio.
- Click on AV Sync Tuning.
- Use your remote’s left and right buttons to adjust the sync until the click sound matches the flash on the screen.
When the sound and flash happen simultaneously, your AV Sync is correctly set.
Solution 3: Verify Audio Output Device
If you’re using external speakers (wired or Bluetooth), make sure:
- All cables are properly connected, or your wireless connection is strong.
- The external device is powered on.
- The speaker is correctly selected as the audio output device on your FireStick.
- The volume on the external device is not muted or too low.
To rule out issues with the external device, disconnect it and check if the FireStick’s built-in speakers produce sound.
Solution 4: Manually Set Up Your Soundbar
Sometimes, your FireStick might not automatically detect or configure an external soundbar. You may need to add it manually:
- Open Settings on your FireStick.
- Select Equipment Control.
- Choose Manage Equipment.
- Click on Add Equipment.
- Select Soundbar from the list.
- Find your connected soundbar and enable Audio Output from TV.
If your soundbar doesn’t appear, it might not be compatible with your TV, and you may need to try a different model. Trying these steps should help resolve most audio problems on your FireStick.
Solution 5: Verify HDMI Port Audio Compatibility
If your FireStick has no sound, the issue might stem from the HDMI port on the device you’re connecting to. While FireStick can plug into any device with an HDMI port, not all HDMI ports support audio output. This problem commonly occurs when using a FireStick with a monitor or PC, as many monitors have HDMI ports that only support video or cannot decode the encrypted audio signal from the FireStick. Additionally, many monitors lack built-in speakers, so even if the video works, there will be no sound. This HDMI audio incompatibility is generally not an issue with modern smart TVs.

Solution 6: Update Your FireStick System
The FireStick OS regularly receives updates to improve stability and add features. If your device hasn’t been updated for a while, it might cause problems such as no sound, flickering display, or app errors.
To ensure your FireStick is up to date:
- Open Settings.
- Select My Fire TV.
- Go to About > Install Updates.
- If updates are available, they will download and install automatically. If not, you’ll see a message indicating your FireStick is up to date.
Solution 7: Adjust Settings for Specific Apps with Sound Issues
If you experience no sound only on certain apps, your FireStick and speakers are likely fine, and the problem may be app-specific. Possible causes include:
- App Compatibility: Some apps may not fully support FireStick OS. This is uncommon with popular streaming apps, but if it happens, try accessing the service via a browser like Amazon Silk if the app offers a website.
- Outdated Apps: Using an old version of an app can cause audio problems. Make sure to update your apps from the Amazon App Store. (Check our guide on updating FireStick apps for help.)
- Corrupted Cache: Cached data might interfere with audio playback. Clear the app’s cache from FireStick settings to remove any corrupted files.
After performing these steps, reopen the app to check if the sound issue is resolved.
Solution 8: Restart Your FireStick
Restarting your FireStick is one of the fastest and easiest ways to fix sound problems caused by temporary glitches or software bugs. Whether you’re dealing with no audio, delayed sound, or out-of-sync playback, a simple reboot often resolves the issue. Whenever you encounter audio problems, restarting should be your first troubleshooting step before trying more complex fixes—you might be surprised how effective it is.
How to Restart Your FireStick:
- Go to Settings.
- Select My Fire TV.
- Choose Restart.
Alternatively, you can unplug your FireStick from the power source, wait a few seconds, and plug it back in.
Solution 9: Reset Your FireStick to Factory Settings
If none of the previous solutions work, the issue could be due to software or hardware problems. Resetting your FireStick to factory defaults is the best way to eliminate software-related causes. Keep in mind, resetting will erase all your data and settings, returning the device to its original state. This step is especially helpful if you’re encountering frequent errors or performance problems.
How to Reset Your FireStick:
- Open Settings.
- Select My Fire TV.
- Click Reset to Factory Default Settings.
- Confirm by selecting Reset in the popup.
After resetting, you’ll need to set up your FireStick again to restore all your preferences and apps.

FAQs
Why is my FireStick sound delayed or out of sync with the video?
Audio delay or out-of-sync sound often occurs due to mismatched Audio Video Sync (AV Sync) settings on your FireStick. Adjusting the AV Sync tuning in your FireStick’s audio settings usually resolves this issue by syncing the audio with the video properly.
How do I manually connect a soundbar to my FireStick?
If your external soundbar isn’t working automatically with FireStick, you can manually add it through Settings > Equipment Control > Manage Equipment > Add Equipment. Then select your soundbar and enable audio output from the TV.
Can using an incompatible HDMI port cause no sound on FireStick?
Yes, some HDMI ports, especially on monitors or older devices, may only support video signals or might not decode the FireStick’s encrypted audio. This can result in video playing but no sound output.
How can outdated apps cause no sound issues on FireStick?
Apps that aren’t updated may have bugs or compatibility issues that affect audio playback. Updating the app from the Amazon App Store or clearing its cache can often fix these sound problems.
What should I check if using external speakers with FireStick but there is no sound?
Ensure your wired or Bluetooth speakers are properly connected, powered on, selected as the audio output device, and have their volume turned up. Sometimes weak wireless connections or faulty cables cause no sound issues.
Will resetting my FireStick delete my apps and settings?
Yes, performing a factory reset will erase all your downloaded apps, personal settings, and data, returning the FireStick to its original state. You will need to set it up again after the reset.
