How to Fix Sound Not Working on Fire Stick

Quick Fixes

• Tweak Fire Stick audio settings from the Gear icon > Display & Audio > Audio > Surround Sound.
• Reset the Fire Stick from Settings > My Fire TV > Reset to Factory Defaults.

Basic Fixes

• Unmute your TV and turn up the volume: Press the Mute button on your TV remote to unmute its volume. Further, increase the volume level using the TV remote and Fire Stick remote.
• Check your network connection: Ensure Fire Stick is connected to a good internet connection. I recommend using at least 10Mbps of internet speed to stream videos on the Fire Stick.
• Replug the Fire Stick: Unplug the Fire Stick from your TV, clean its connector thoroughly, and re-insert it.
• Inspect the AV(Audio/Video) Receiver: Check the AV Receiver light indicator to ensure it is powered on.
• Ensure Bluetooth earphones aren’t connected to the Fire Stick: Disconnect all connected Bluetooth earphones/headphones to avoid sound routing to them instead of your TV.
• Ensure HDMI port supports audio: Check your TV product manual to verify its HDMI port supports audio. You can also Google the TV model to verify these details.

Fix 1: Check Audio Settings in the Fire Stick

Fire Stick lets you choose the best sound output supported by the playing content (e.g., Dolby Digital, Dolby Atmos). If your TV or connected speaker isn’t compatible, you may not hear any sound. Tweak the Fire Stick audio settings manually to fix it.

Step 1: Navigate to the Gear icon on the Fire Stick home and select Display & Audio.

Step 2: Select Audio and open Surround Sound.

Step 3: Switch it to Best Available and check the sound output. If the sound issue persists, set it to PCM.

Fix 2: Run the AV Sync Tuning

Are you noticing an audio delay in the content you’re watching on the Fire Stick? Fret not; run the AV Sync Tuning in the Fire Stick settings to fix it.

Step 1: Open Display & Audio settings from the Fire Stick home menu.

Step 2: Select Audio and scroll down to launch AV Sync Tuning.

Fix 3: Manually Set up the Soundbar

If your Fire Stick doesn’t recognize the connected third-party soundbar, you may encounter the no sound issue. To fix it, set up your soundbar manually under Fire Stick settings.

Step 1: Open Equipment Control from the Fire Stick home menu.

Step 2: Select Manage Equipment.

Step 3: Click Add Equipment, select Soundbar, pick your brand from the list, and follow the on-screen instructions to complete its setup.

Fix 4: Reset the Fire Stick

If nothing works, reset the Fire Stick to factory defaults to fix its sound not working issue.

Note: Resetting the Fire Stick removes all downloaded content, including your in-app purchases.

Step 1: Open My Fire TV under Fire Stick settings.

Step 2: Scroll down and select Reset to Factory Defaults.
