As an avid Roku user and streaming expert, I know how frustrating it can be when the audio falls out of sync with the video. Whether it’s dialogue that doesn’t match lip movements or sound effects that are delayed, it’s a jarring experience that takes you out of the content.
Luckily, after years of working with Roku devices, I’ve discovered several simple solutions that can help you quickly resolve audio sync problems yourself. In most cases, you can get your sound back on track in just a few minutes without any technical know-how.
In this comprehensive troubleshooting guide, I’ll walk you through the 11 most effective fixes for Roku audio sync issues, starting with the quickest and easiest options. I’ll also share some tips for preventing future audio problems and answer frequently asked questions.
But first, let’s look at a few of the most common reasons your Roku audio may become out of sync:
- Weak or unstable internet connection
- Outdated software or firmware
- Incorrect audio settings
- Using an external sound system
- Loose or faulty cables
- Bugs or glitches in the Roku OS or apps
While some audio sync issues are caused by more technical problems, the good news is that most can be fixed by some simple troubleshooting on your end. So if you’re ready to get your sound synced up, let’s dive into the step-by-step solutions!
Quick Fixes to Try First
Before attempting any more advanced troubleshooting, I always recommend starting with these quick and easy fixes:
1. Perform a System Restart
Often, simply restarting your Roku device can resolve any minor software bugs or glitches that may be throwing off the audio sync. To do this:
- Press the Home button on your Roku remote
- Navigate to Settings > System > System Restart
- Select Restart and wait for your device to reboot
For more detailed steps, check out our guide on how to restart your Roku TV.
2. Power Cycle Your Roku Device
If restarting through the menu doesn’t work, you can also try a full power cycle:
- Turn off your TV and unplug your Roku device from power
- Wait 30-60 seconds, then plug it back in
- Turn your TV back on and wait for the Roku to reboot
This clears the cache and can reset processes to get your audio back in sync. By the way, if you notice your Roku keeps restarting on its own, that could indicate a separate issue.
3. Check Your Connections
Loose or faulty cables are another common culprit for audio issues. Take a moment to:
- Ensure your HDMI cable is securely plugged in at both ends
- Check for any visible damage or fraying on the cable
- Try a different HDMI cable or input on your TV if you have one
Adjusting Audio Settings
Still having sync issues? The problem may lie in your Roku’s audio settings. Here’s how to check and adjust them:
4. Switch to Stereo Audio Mode
If your Roku is set to surround sound but you don’t have a surround sound system, it can cause sync issues. To switch to stereo:
- Press the Home button, then go to Settings > Audio
- Change the Audio Mode to Stereo
- Set HDMI to PCM-Stereo
5. Disable Volume Mode
Some users have reported that disabling Roku’s volume mode feature resolved their audio delay. To do this:
- While streaming, press the Star button on your remote
- Go to Volume Mode and switch it to Off
6. Reset Audio Configurations to Default
If your Roku’s audio settings have been changed, it may cause problems. To reset them:
- Go to Settings > System > Advanced System Settings
- Select Factory Reset and choose Reset TV Audio/Picture Settings
- Press Play/Pause 3 times to confirm
Updating Software and Clearing Cache
Like any streaming device, Roku requires regular software updates for optimal performance. It can also help to clear the cache occasionally. Here’s how:
7. Check for and Install Software Updates
- Press the Home button, then navigate to Settings
- Choose System > System Update
- Select Check Now to manually check for updates
- If an update is available, let it install
Installing the latest firmware is also key for resolving issues like the Roku blinking white light.
8. Clear the Cache on Your Roku
- From the Home menu, press Home 5 times
- Press Up once, then Rewind 2 times
- Press Fast Forward 2 times
- Wait for your device to restart
Checking Network and Streaming Issues
Audio sync problems can sometimes be attributed to internet or streaming issues rather than your Roku itself. A couple things to try:
9. Test Your Internet Connection Strength
- Go to Settings > Network About
- Look for a “Good” or “Excellent” signal strength
- If it’s poor, try moving your router closer or contacting your provider
If you’re having trouble connecting, you may need to find your Roku IP address to configure your network settings.
10. Use Your TV’s Internal Speakers
If you’re using an external sound system, try switching to your TV’s built-in speakers. If the audio is synced, the issue is with your sound system, not the Roku.

Last Resort Steps
If you’ve tried all of the above to no avail, you have two final options:
11. Factory Reset Your Roku Device
- Go to Settings > System > Advanced System Settings > Factory Reset
- Choose Factory Reset Everything and confirm
- Wait for the reset process to complete
Note that this will erase all settings and preferences, so only do this as a last resort. It can also help if your Hisense Roku TV won’t turn on.
12. Contact Roku Customer Support
If nothing else has worked, it may be time to reach out directly to Roku Support. Have your device model and serial number ready and be prepared to troubleshoot with an agent.
Key Takeaways
- Most Roku audio sync issues can be fixed quickly by adjusting settings or connections
- Keeping your software and firmware up-to-date is important for preventing problems
- Both your Roku device and your streaming network/apps can cause sync issues
- If troubleshooting yourself doesn’t work, don’t hesitate to contact Roku Support
With these tips in mind, you should be well-equipped to handle any audio delays or sync problems that arise. While it can be a nuisance, just work through the steps one-by-one and you’ll likely find a solution.
