Amazon fire stick 4k sound out of sync

amazon fire stick 4k sound out of sync

*Edit The working Stick had upgraded to Amazon Fire TV Stick 4K: Fire OS () Guessing this may be issue.. Seems one cannot simply walk into. If the sound is coming from a separate audio system or soundbar then check that for lip sync adjustment. You may need to connect the Firestick. Amazon is silent on the issue even though it goes back a few years. I've tried every combination of audio/video settings on the Fire itself.

It’s one thing for subtitles to go all Usain Bolt on you and spoil the story, but it’s another thing for your audio to get ahead of the video or vice versa. Subtitles can be turned off. But watching your favorite TV show on mute? That’s not really an option now, is it?

Roku Video and Audio Not in Sync – What to Do

If you’re using a Roku TV or a Roku streaming stick, you’re not desync-proof. Bad stuff happens with any streaming service, receiver, and OS. Here are a couple of things that might help you fix the issue before deciding that Roku’s no good.

Change Roku Audio Settings

Roku devices have a very annoying default feature that can sometimes cause audio lag. It’s called the Auto Detect feature. This feature purportedly detects the audio decoding capabilities of the device and any sound bar or AVR setup you may have. But, most often than not, it’s not working as it should.

  1. Go to your Roku Home screen.
  2. Select Settings.
  3. Go to Audio.
  4. Select a different setting like HDMI or Stereo.
  5. Also check the PCM feature, if it’s available.

Common Netflix Audio Video Desync

Sometimes, you may experience audio lag only on certain streaming platforms. Netflix and Hulu tend to be the top contenders most of the time, with Netflix pretty much edging Hulu for the top spot. Here’s what you can try to fix the Netflix audio.

  1. Launch the Netflix channel.
  2. Start a video.
  3. Select the Audio and Subtitles menu.
  4. Select English from the list.

This is also something that you can try for other platforms too. But this fix will only work if the platform you’re using can override the device’s audio settings. Netflix does. Not many others do.

Check the Connection

Are you trying to watch something in 4K but keep running into audio desync? This can often happen if you’re not using a premium quality cable. Upgrade your cable to ensure the integrity of the signal transfer.

Note that if you’re using a Roku Streaming Stick+, you won’t need a cable. Just make sure that your TV can support HDMI or HDCP connections.

What If You’re Using a Sound Bar or AVR?

If you’re using something other than your TV to project sound, then you’ll also have to make sure that your sound bar or sound system are also compatible with HDMI Any inconsistencies in this configuration and you could get audio lag, no audio at all, or worse – a lower resolution than what you’re aiming for.

For Non-Roku TV Users

Audio lag is something you can experience even if you’re not using a dedicated Roku smart TV. Say you’re using a regular LG or Samsung smart TV. How can you fix audio lag? – Tinker amazon fire stick 4k sound out of sync the settings on your device.

Changing the Roku audio settings is one thing. But, if your TV isn’t properly calibrated, any changes to the Roku audio settings may be done in vain. Check your device’s sound out or sound mode settings and see if everything there line’s up with what you’re using.

For example, if you’re listening through an optical connection sound bar then make sure the sound mode is set to an optical setting. If you’re using the TV speakers, make sure to check the TV speaker option or internal TV speaker option.

You should keep in mind that sometimes a firmware update on a smart TV can revert the amazon fire stick 4k sound out of sync settings back to default. Hence, why sometimes audio lagging comes out of nowhere.

Could Your Bandwidth Be Responsible for Audio Lag?

Some bandwidth is always necessary, especially when streaming in high resolution. If you’re thinking 2k or 4K streaming, it’s best to have a bandwidth of at least 25 Mpbs.

bandwidth generic

But, even on a smaller bandwidth, you can always start a movie or episode, pause it, and let it load for a while before starting to watch it.

When you don’t have enough bandwidth, what usually happens is that your video will load very slowly. But, both audio and video load at the same time. You shouldn’t experience anything along the lines of seeing video with laggy audio or the other way around. Don’t be too quick to scream at your provider because of audio lag.

Bonus Tips and How to Narrow Down the Issue

One thing you have to keep in mind is that the problem won’t always be on the user end. Audio sync issues can be coming from the host. For example, if you can watch thirty channels in impeccable quality and only one of them is acting up, then the problem is unlikely caused by your Roku device or any settings on your end. Again, see the Netflix issue previously mentioned.

If you’re using a receiver or a sound bar and you’re experiencing audio or video lag constantly, try removing the sound bar from the equation and set your device on internal speakers. If it goes away, then your sound bar may be in fact incompatible with your Roku device.

Input Lag

Input lag is an issue that doesn’t only plague gamers. Try putting your TV in game mode or try watching something in a lower resolution. Game mode is designed to lower the picture quality and improve the visual response time.

If one of those two things fixed the problem then the issue isn’t with your Roku streaming stick but rather the TV’s inability to process high resolution videos and decode high quality audio signals.

Take It One Step at a Time

As you can see, there are many reasons why your audio, video, or both can be out of sync badly when you’re watching something on a Roku-enabled device. Sometimes a rewind, fast-forward, pause, and play action on the remote may be enough to fix things. But, even if that’s not enough, there’s a lot of troubleshooting you can do on your own.

However, the big question is, how often does this really happen? Have you experienced audio video sync problems on Roku smart TVs or on other TVs with a Roku stick attached? Have you noticed certain channels apart from Netflix that constantly show signs of incompatibility with Roku? Let us know in the comments section below.

The most common troubleshooting step that is suggested for almost any electronic device is to reboot it.

Rebooting the device helps eliminate any bad piece of code that might exist within the system’s memory, thus bringing the device back into a fresh state.

To power cycle, your Roku device, unplug it from its power source, wait for a few seconds, and then plug it back in.

This will reboot your device, thereby starting your streams all over, this time with the audio and video in sync.

Change Audio Settings to “Stereo”

If the previous solution didn’t fix the issue for you, the chances are that the audio lag results from misconfigured settings.

The simplest one you can try to fix is the audio settings on your TV. Switching the audio settings to ‘Stereo’ should fix your issue right away.

To do this:

  1. Press the home button on your Roku remote.
  2. Scroll up or down until you amazon fire stick 4k sound out of sync the ‘Settings’ option and click on it to open it.
  3. Select the ‘Audio’ option.
  4. Change the audio mode to ‘Stereo.’
  5. After this, set the HDMI mode to PCM-Stereo.

Doing this should bring your audio back into sync. If your Roku device has an optical port, make sure you set the ‘HDMI and S/PDIF’ option to PCM-Stereo.

Check All Connections

The solution mentioned above should work most of the time. However, if it doesn’t, try checking your internet connection and making sure it is stable.

If your internet strength is poor, it can affect your streaming quality, thus causing the audio issue.

If you are using a wired internet connection, make sure that the Ethernet cable is not damaged and connected properly between your TV and your router.

You can also lookout for the best wired routers in the market for a strong internet connection.

Other issues that can cause problems with your TV are loose HDMI or power cable connections.

While this may seem trivial, it goes undetected a lot of times. This solution works even for issues like your Roku not having sound.

Make sure that the HDMI and power cables are connected to the TV to avoid any problems.

Disable and Enable Volume Mode on the Remote

One of the methods that have worked for a lot of users is to make a quick change to the volume settings on the remote.

While this seems too simple to be true, it has been quite effective in the past. 

All you have to do is disable the ‘Volume Mode’ on your remote control and re-enable it again. To do this: 

  • Press the Star or Asterisk (*) button.
  • Scroll to Volume Mode.
  • Select OFF by scrolling right.

Press the Star (*) key on the remote

Another setting that you can change to quickly resolve your out-of-sync audio is Audio Levelling.

While your TV is still playing, press the Star (*) key on your remote. This opens up the volume settings.

Next, find the ‘Audio Levelling’ option on your device. If it is enabled, just turn it off, and that should bring your audio back into sync with your video.

If your Roku Remote is not working, try replacing the batteries or re-paring the remote with Roku.

Clear the Cache 

Another reliable way to fix most issues with electronic devices is to clear the cache memory.

This is because Clearing cache frees up more processing power, and that can fix the audio lag.

The best way to do this is to simply reboot your device. However, if you have already tried power cycling your Roku device and still find the same issue, here is another way you can clear your device’s cache:

  1. Open the main menu and make sure that you are on the ‘Home’ tab.
  2. Press the following buttons on your remote consecutively:
    • Press the Home button 5 times.
    • Press Up.
    • Press Rewind 2 times.
    • Press Fast Forward 2 times.
  3. The device will take about 15 &#; 30 seconds to clear the cache, and then the device will restart.

Adjust Video Refresh Properties 

While it may seem counter-intuitive, tweaking your video settings might actually work in syncing your audio back to normal.

Audio can sometimes desync if your Roku is constantly having issues with buffering. 

Normally, your Roku device will pick the best bit rate that matches your network speed to give you the best viewing experience. However, sometimes you will need to adjust it manually.

To do this, follow these steps:

  1. On the Roku remote, press the Home button five times.
  2. Press the reverse button three times.
  3. Press the Fast Forward button two times.
  4. A Bit Rate Override menu will appear on your screen. Select the Manual Selection option.
  5. Try selecting a lower rate and see if it fixes your problem. If it doesn’t, you can repeat the sequence and select an even lower bitrate until the issue is resolved.

Reset Your Roku

If none of the above solutions worked for you, the only thing left for you to do is to reset your Roku device to its factory defaults.

However, it is essential to remember that you will lose all your saved settings and customizations and you will have to set it up again.

To reset your Roku device:

  1. Press the Home button on your Roku remote.
  2. Scroll up or down to find Settings.
  3. Select System and go to Advanced System Settings.
  4. Select Factory Reset option.
  5. If you have a Roku TV, select Factory Reset Everything.
  6. Follow the on-screen instructions to finish resetting your device.

Final Thoughts

So there you have it. Unfortunately, audio desyncing is a common problem that a america ferrera parents of Roku users experience. However, it is relatively easy to fix, as seen in the article above.

However, if none of these solutions worked for you, the only thing left to do is to contact Roku Customer Support.

Make sure that you mention all the different troubleshooting steps you took, as this will make it easier for the support team to assist you.
