Amazon Video Sound Not Working | Fixes That Stick Fast

Amazon Video sound not working is usually a mute, a wrong audio output, or an audio-track mismatch, and sound often returns after a few clean checks.

No sound with a sharp picture feels like a bad joke. The show plays, subtitles move, and your room stays quiet. Most of the time, Prime Video isn’t “down.” Audio is just getting lost between the app, your streaming device, and your TV or soundbar.

The fastest way out is a simple order: confirm the TV is actually outputting sound, confirm Prime Video is using a playable audio track, then reset the HDMI handshake. Do those in that sequence and you’ll avoid random setting-hopping.

This article walks through quick restores first, then deeper fixes for smart TVs, Fire TV, Roku, Apple TV, phones, tablets, consoles, and browsers. You’ll also get a short way to tell when the title itself is the culprit.

Why Prime Video Can Play With No Sound

Video and audio don’t always fail together. A device can decode the video stream fine while audio output gets muted, routed elsewhere, or stuck in a handshake glitch. That’s why you can see everything but hear nothing.

There are three common breakpoints. One is output routing, where sound is going to Bluetooth, headphones, ARC, or a receiver input you aren’t using. Another is audio format, where a title defaults to 5.1 or Dolby audio but your current chain is happier with stereo. The last one is app state, where Prime Video’s player gets stuck after pausing, seeking, or an ad break.

Run a quick three-part check to locate the layer that’s failing. Try a second title in Prime Video, try another app on the same device, then try Prime Video on a different device. Those quick swaps tell you whether this is the TV chain, the device, or the Prime Video player.

Symptom	Likely Cause	First Move
Other apps have sound, Prime Video is silent	Audio track choice or app state	Switch audio track, then relaunch app
Phone has sound, TV setup is silent	TV output route or HDMI handshake	Check TV output, then power-cycle TV and soundbar
Only some titles are silent	Track format mismatch	Select a stereo track and replay
Sound drops after pausing or seeking	Handshake glitch	Back out of playback and resume, then restart device

Fixing Amazon Video Sound Not Working On Any Device

If you want sound back fast, start with steps that reset the audio path without wiping your apps or settings. Each action is safe. Stop as soon as audio returns.

Clear mute and raise volume — Turn volume up on the TV and on any soundbar or receiver, then toggle mute once to rule out a stuck mute state.
Switch titles for a quick test — Play a different Prime Video title for 15–20 seconds; if sound works there, the issue is likely the first title’s track choice.
Change the audio track — Open the audio menu and pick another audio option, then resume playback to force a fresh decode.
Exit Prime Video fully — Close the app, not just back out, then launch it again.
Restart the device — Use the device restart option, or unplug the device for 20 seconds if it has no restart menu.
Power-cycle the TV chain — Turn off TV and soundbar/receiver, unplug both for one full minute, then plug back in and turn on.

After that pass, replay the same scene. If the title stays silent on one device only, you’ll get better results by adjusting that device’s audio output mode. If the title is silent across multiple devices, focus on track selection and account/session refresh.

Check TV Output And HDMI Audio Routing

TV routing is the silent troublemaker because it can change without you noticing. Your TV may still show video from HDMI 1 while sending audio to Bluetooth headphones, an ARC soundbar, or a receiver that’s on the wrong input.

Confirm Where Sound Is Going

Set the active output — In TV sound settings, choose TV speakers, HDMI ARC/eARC, optical, or Bluetooth, and match it to what you’re using.
Disconnect headphones and Bluetooth — Unplug wired headphones and turn off Bluetooth audio so sound can’t get pulled to another device.
Select the right soundbar input — Set the soundbar or receiver to ARC/TV/optical/HDMI as needed so it’s actually listening.

Reset The HDMI Handshake

HDMI audio is negotiated in the background. That negotiation can glitch after input changes, a pause, or an ad break. A handshake reset often restores audio right away.

Reseat the HDMI cable — Unplug the HDMI cable at both ends, then plug it back in firmly.
Try a different HDMI port — Move the device to another HDMI input to rule out a flaky port.
Swap the HDMI cable — Use a known-good cable; borderline cables can pass video while audio negotiation fails.

Match Audio Format To Your Setup

Look for settings like Digital Audio Out, HDMI Audio Format, Pass Through, or eARC Mode. If you use TV speakers, stereo output is the clean test. If you use a soundbar or receiver, Auto or Pass Through often works best, but one toggle can make the difference.

Set Digital Audio Out to Auto — Auto can adapt per title and often restores audio without extra tweaks.
Switch to PCM for a stereo test — PCM forces stereo output and can restore sound when surround output is failing.
Toggle eARC or ARC — Turn eARC off, then on again, or toggle ARC settings to refresh negotiation.

Prime Video Player Settings That Restore Audio

When Prime Video is the only silent app, the fix is often inside the player. Many titles have multiple audio tracks, and the app may default to a track your current chain can’t handle cleanly.

Switch Audio Tracks The Right Way

Open playback controls — While the title plays, bring up the on-screen controls.
Open audio options — Choose the audio and subtitles menu.
Select a different track — Pick a Stereo option or a plain language track rather than a 5.1 option.
Play for 15 seconds — Let it run long enough to confirm the change stuck.

If sound returns after a track swap, keep watching for a few minutes. If it drops again after seeking, pause once, back out to the title page, then resume. That rebuilds playback and can clear a stuck audio buffer.

Refresh The App Without Losing Your Lists

Apps can get stuck after updates or after long sessions. You can clear bad state without wiping your device.

Force-close Prime Video — Use the device app switcher or app list and close it fully.
Restart the device — A restart clears background audio services that can hang.
Update the app — Install the latest Prime Video update from your app store.

On Android TV, Fire TV, and Android phones, clearing cache is a strong next move. Cache clears temporary files, not your watchlist. Save “clear data” as a later step since it logs you out.

Device Audio Output Fixes By Platform

Once TV routing is correct, the next layer is the device output mode. Each platform names it differently, but the goal is the same: pick an output mode your TV chain can decode.

Fire TV output mode — In Display & Sounds, set Audio to Best Available, test, then switch to PCM if silence stays.
Roku audio mode — In Audio settings, set HDMI to Auto, test, then set to Stereo for a clean format test.
Apple TV audio format — Set Audio Format to Auto, then toggle Change Format and test Dolby Digital 5.1 if Auto is failing.
Smart TV built-in app — Restart the TV from its power menu, then check Digital Audio Out for Auto or PCM depending on your setup.
PlayStation HDMI audio — Set HDMI audio to Stereo Uncompressed to test, then move back to Bitstream once sound is stable.
Xbox HDMI audio — Set Stereo Uncompressed to test, then switch to Bitstream Out once the chain is stable.
Android phone or tablet — Turn off Bluetooth, raise media volume, then clear Prime Video cache in app settings.
iPhone or iPad audio route — Disconnect AirPlay targets, raise media volume, then close and reopen Prime Video.
Browser playback — Unmute the tab, confirm site sound is allowed, then try a private window to rule out extensions.

If you run a receiver in the middle, try a direct connection test. Plug the streaming device straight into the TV for one session. If audio returns, the receiver path is where the format mismatch is happening.

Network And Format Issues That Can Mute Audio

It sounds strange, but network hiccups can affect audio while video keeps moving. If audio packets arrive late or out of order, the player may keep video buffered while audio stalls. This can show up more with higher-bitrate tracks.

Stabilize Playback

Restart your router — Power it off for 30 seconds, then let it boot fully before testing again.
Try Ethernet — A wired connection reduces dropouts that can break audio sync.
Disable VPN routes — Some routes add buffering that can trip audio playback even when picture looks fine.
Reduce device load — Close other streaming apps and background downloads so the device can keep audio steady.

Use Stereo As A Clean Diagnostic

Surround tracks ask more from every link in the chain. If one link can’t keep up, you may get silence or audio that drops in and out. A stereo test is a simple way to confirm a format clash.

Select a stereo track — Use the Prime Video audio menu and pick Stereo when available.
Set the device to PCM — PCM forces stereo output and removes a surround decode step.
Disable sound effects — Turn off TV sound modes like virtual surround while testing.

When The Title Or Session Is The Real Problem

Sometimes your setup is fine and the problem sits with the title stream or a stuck session. This is more likely when one title is silent across multiple devices, or when audio drops after the same scene every time.

Try two quick checks. First, jump a few minutes earlier and later to see if it’s a single bad segment. Next, switch the audio track or language if the title offers one. If audio returns with a different track, your setup is fine and the first track is the issue.

Test another title — Pick a different Prime Video show and confirm sound works there.
Switch profiles — Try a different Prime Video profile, then replay the title.
Sign out and sign back in — This refreshes session state and licensing without changing device audio modes.
Reinstall Prime Video on one device — If one device stays broken, reinstalling is often faster than chasing deeper toggles.

If amazon video sound not working persists across titles and devices, check whether Prime Video is having a service issue in your region and try again later. If the issue is tied to one device after all checks, focus on that device’s audio mode and app reinstall steps.

Fast Final Checks To Keep Sound Stable

Once sound is back, run a short stability test so you don’t get burned again mid-episode. Replay the original scene, pause, resume, then seek forward and back. If audio survives those actions, the chain is stable.

Replay the original scene — Confirm the exact spot that was silent now has audio.
Pause and resume — Wait 10 seconds, resume, and listen for clean return.
Seek forward and back — A quick seek tests the audio buffer and handshake stability.
Confirm another app — Play a clip in another streaming app to ensure routing still matches your setup.
Note the working settings — Write down your TV digital output mode and device audio mode so you can restore them after updates.

If you still hit amazon video sound not working after all steps, collect a few details before contacting Amazon: device model, app version, TV model, soundbar or receiver model, and whether the title track is stereo or 5.1. That info helps you get the right fix faster.

If you want one quick recap to keep handy, remember this order: verify TV output route, switch Prime Video audio tracks, reset the HDMI handshake, then test stereo output with PCM. That sequence solves the bulk of “silent Prime Video” cases without turning your settings into a mess.
