Amazon Fire Stick makes for a great streaming device that gives you access to your favorite movies, and subscription services such as music and movies. Unfortunately, it can have performance issues like fire stick sound cutting out and stuttering. In this article, we explain how to fix the issue of your fire stick cutting out. 

Your fire stick often cuts out and stutters for various reasons including a slow and unstable internet connection, an inadequate power supply, software bugs, loose cables, and caching issues. To resolve the problem quickly, try restarting, resetting, or reseating your Fire Stick. 

Let’s look at these fixes in detail.

By the way, if your Fire Stick has no sound at all, then you need a different guide. Check out our guide on how to fix the Fire Stick no sound issue.

Here are the possible causes, including brief hints on how to sort out the problem with ease.

1. Inadequate Power Supply

If you’ve plugged your fire stick’s power cord into your TV, the television might not output adequate power through the USB port to power your fire stick. If this happens, you might experience this and other performance issues.

Bottom line is that there isn’t enough power going to your Fire Stick. When your Fire Stick is experiencing low power issues, it will certainly be slower than normal and will likely stutter. It will also try to reboot itself to solve the problem while undergoing extensive processing.

The only way to fix the sound problem is to plug the fire stick power supply directly into your electrical outlet.

2. Software Bugs

Sometimes, the sound issue can be just a fluke. This often happens when system errors hinder a fire stick from working as required.

You can fix software bugs by restarting the streaming device.  

3. HDMI Cable is Poorly Connected

If your HDMI cable is partially connected, your Fire Stick sound can keep disconnecting from time to time.

In this case, the perfect remedy is to ensure your fire stick is powered on and then reconnect the HDMI connector.

All you need to do is to reseat the Fire Stick in its HDMI port and that will typically fix the sound stutter. If it doesn’t work the first time, try it a few times or try a different port on your TV.

4. Input Problems

It could be that your HDIM port has malfunctioned.

You should switch your TV to a different input and see whether that resolves the issue.     

5. Outdated Apps

The app you are using should be up-to-date. If it isn’t, you might need to uninstall and reinstall it.

6. TV Resolution Hogging Processing Power

The higher the resolution of your TV, the more processing power it will require. This will increase the demand for the Fire Stick to deliver higher-resolution content faster. This requires a lot of processing. If the Fire Stick is unable to keep up, it will stutter as it struggles.

To fix this problem, try the following:

  1. Turn off Dolby if it’s enabled
  2. Lower the resolution of the TV. For example, if the resolution is set to 1080p, try to change it to 720p. This normally doesn’t make a big difference for TVs smaller than 42 inches.

7. Other Devices Connected

In some cases, another device may be connected to your Fire Stick and you are unaware. This can hog the Fire Stick’s processing power and cause it to stick and stutter. If you have other Amazon devices like the Echo Dot, Echo Plus, or Fire Tablet, check if any of these devices have connected to the Fire Stick and disconnect them. 

If it’s an Echo Dot, for example, all you need to do is say “Alexa disconnect from FireTv”.

8. Filled Cache

Your Fire Stick’s cache is a file or set of files that temporarily hold content that you watch regularly. This allows the Fire Stick to get frequently requested content quickly. However, sometimes this cache can fill up. 

If this happens, the Fire Stick won’t be able to buffer and may experience stuttering. 

To fix the problem, clear the Fire Stick cache. To do this for Amazon Music, for example, go to Home/settings/apps/amazon music Force Stop, clear cache

To do this for Netflix for example, go to Home/settings/apps/Netflix Force Stop, and clear cache.
