Sound issues in Fire TV Stick can ruin the perfect weekend you had planned for your family. Also, it can be confusing to determine if the problem is due to your television or Fire TV Stick. We will discuss every scenario and enable sound on Fire TV Stick.

1. Unmute TV and Turn up Volume

This may seem like a simple step, but your little ones might have put the TV on mute. Double-check if the TV is indeed in normal mode and increase the volume.

If you are using an external sound system setup at home, you need to unmute it as well.

2. Reset Amazon Fire TV Stick

A loose HDMI connection may lead up to sound issues on Fire TV Stick. Unplug Fire TV Stick from the TV, turn off the plug and wait for a few minutes.

Connect your Fire TV Stick to TV again and try playing video to check if the sound works.

3. Switch to High-Speed Internet Connection

If you are trying to stream a movie or TV show on a slow internet connection, you will notice glitches with video and audio output. You will also experience an audio delay.

Connect your Fire TV Stick to a faster, reliable internet connection. If your Wi-Fi router has dual-band support, connect to 5 GHz Wi-Fi frequency band.

4. Turn on AV Receiver

Some users opt for an AV receiver to push the Fire TV Stick’s audio through external speakers (for instance, a surround sound home theatre system). Make sure the AV receiver is powered on and have Fire TV Stick as one of the sources.

Closely inspect the AV receiver. If it’s powered on, you will notice lights turning up. If not, press the power button and turn it on. On the flip side, if the AV receiver is indeed on and you are still facing sound issues, then continue with the rest of the troubleshooting methods.

5. Make Settings Change in Surround Sound

Fire TV Stick allows users to select the best possible sound output based on the content sound output device. Some Disney+ and Netflix content support Dolby Digital+ and if the connected speaker or soundbar doesn’t have Dolby Digital support, you might notice no sound from the video.

If you are playing content through a web player on the Amazon Silk browser, make sure the player isn’t on mute mode.
