The YouTube app lets you watch content in Ultra HD resolution with your Amazon Fire TV Stick 4K. YouTube now also supports videos in Dolby Atmos and Dolby Digital 5.1 for an immersive audio experience. But some users complain about not being able to enjoy such spatial audio quality on YouTube.

Users report about no audio in the YouTube app on their Amazon Fire TV Stick 4K. This post will share solutions to prevent exactly that and allow users to enjoy watching their favorite videos.

1. Check if the Audio Is Muted

The Fire TV 4K remote has a dedicated Mute button to disable audio. And you might have pressed it previously to avoid disturbing anyone around you. How about pressing the Mute button again and checking if the problem gets solved?

2. Disconnect Bluetooth Devices

You can connect your Bluetooth devices, like headphones and speakers, with your Fire TV Stick 4K. That means that once they are connected, the speaker of your TV will stop transmitting the audio output.

3. Change Volume Using Alexa

Alexa lets you give voice commands to control apps and functions on your Amazon Fire TV Stick 4K. You can change the volume of the YouTube app by pressing the Alexa button on the remote and saying, ‘Alexa, Increase Volume.’ The volume levels of your TV speakers should increase by five levels. See if this solves the issue.

When you ask Alexa to increase or decrease volume, the volume levels get incremented by five by default. But you can also change the Volume Increments for your Fire TV Stick 4K and see if that solves the problem with the YouTube app. This is for when you most wish to control volume levels using Alexa.

As the name suggests, Volume Leveller helps in setting a consistent volume level for all your streaming content and apps. It may be restricting an increase in the volume of the YouTube app. Here’s how you can check and disable the feature.
