Amazon Prime Sound Not Working | Fixes That Work Fast

Guide / By

Prime Video audio problems usually come from mute and volume settings, HDMI output choices, or a stuck app session; the steps below restore sound.

When Prime Video goes silent, it often feels like the app is broken. Most of the time, the picture is fine and the audio is being blocked somewhere between the app and your speakers. The trick is to test the chain in order: app, streaming device, TV or receiver, then the cable path.

This guide keeps that order. You’ll start with fast checks, then jump to steps for your device. Most fixes take five minutes tops.

Amazon Prime Sound Not Working On TV And Fire TV

If the issue shows up on a TV, Fire TV Stick, or Fire TV Cube, treat it like a handshake problem. TVs and receivers negotiate audio formats over HDMI. One mismatched setting can leave you with silence while other apps still play sound.

Start with these checks in order. Stop as soon as audio returns so you don’t change extra settings that were already fine.

  1. Raise TV volume — Turn the TV volume up past a normal level and confirm mute is off.
  2. Switch audio output — On the TV, cycle Speaker, HDMI ARC/eARC, and Optical to match where your sound actually comes from.
  3. Play another app — Open YouTube or another streaming app to see if the TV has sound outside Prime Video.
  4. Restart the Fire TV — Use the on-screen restart option, not just the TV power button, so the stick fully reboots.
  5. Unplug power for 30 seconds — Disconnect the TV and Fire TV from power, wait, then plug both back in.

If other apps play audio but Prime Video stays quiet, the app may be stuck on an audio format your setup can’t decode. That can happen after you connect a soundbar, change HDMI ports, or toggle a surround setting.

  • Change the Prime audio track — While a title plays, open the audio or languages menu and choose a different track, then switch back.
  • Toggle Fire TV audio output — In Fire TV settings, switch from Best Available to PCM, test, then return to your preferred mode.
  • Disable surround processing — Turn off virtual surround or volume leveling on the TV or soundbar, then test the same scene again.

Fast Checks That Fix Most Audio Drops

These fixes work across almost any device. They’re also the least disruptive, so they’re a good first pass when you see no sound, low sound, or sound that cuts out mid-scene.

  1. Check in-app mute and volume — Some devices can mute an app session while system volume stays up.
  2. Test another title — Try a different movie or episode in case the current stream has a bad audio track.
  3. Turn off Bluetooth audio — Disconnect earbuds or speakers that may have stolen the audio output.
  4. Close other audio apps — Stop music, podcasts, or casting sessions that can hold the audio device.
  5. Confirm you’re not casting silently — If you’re using AirPlay or Chromecast, check the receiving device volume too.

Next, do a quick format check. Prime Video titles can use stereo, 5.1, or Atmos depending on the device and plan. If your TV or receiver expects one format and the stream sends another, you can get silence or clipped audio.

  • Set audio to stereo for a test — Switch your device output to stereo or PCM, play a loud scene, then decide if surround can be re-enabled.
  • Turn off audio passthrough — On some TVs, passthrough can fail if the receiver is slow to sync after pause or resume.
  • Swap HDMI ports — Use a different port, then re-run the device’s audio setup so it re-detects capabilities.

Device-Specific Fixes By Platform

Once the basics are done, target the platform you’re watching on. Each device family has one or two common traps that can mute Prime Video while other apps look normal.

Roku Streaming Players And Roku TVs

Roku can hold onto an audio mode after a firmware update or a display change. That’s why you may get silence on one app and not another.

  1. Run audio auto-detect — In Roku audio settings, set HDMI to Auto Detect, then reboot the Roku.
  2. Force stereo output — Set Audio mode to Stereo and test Prime Video, then move back to Auto if it works.
  3. Remove and add Prime Video — Delete the channel, restart the Roku, then install it again to refresh app data.

Apple TV

Apple TV can map audio through HomePods, AirPlay speakers, or an AVR. A mismatch can show up as quiet dialog, missing center channel, or no sound at all.

  • Confirm audio output device — Open the Control Center and make sure the output is the TV or your chosen speakers.
  • Disable Change Format for testing — Set audio format to Automatic, test Prime, then re-enable a forced format only if needed.
  • Restart the Apple TV — Use Settings to restart so the audio engine reloads cleanly.

Android Phones And Tablets

On Android, volume streams can be separate. Media volume may be low while ringtone volume is high, which makes the phone seem fine until you start a video.

  1. Raise media volume — Use the volume buttons while a Prime title is playing so you adjust the correct channel.
  2. Turn off Do Not Disturb — Some devices mute media under certain DND rules or focus modes.
  3. Clear app cache — In app settings, clear cache, then sign in again if prompted.

iPhone And iPad

On iOS and iPadOS, the Silent switch and connected audio devices cause the most confusion. Also check that you aren’t routing sound to AirPods left in another room.

  • Disconnect AirPlay — Open Control Center, tap AirPlay, and choose iPhone or iPad as the output.
  • Toggle silent and ring — Flip the switch and set volume while a title is playing to refresh the media route.
  • Reinstall Prime Video — Delete the app, restart the device, then install again to reset permissions and data.

Smart TVs And Game Consoles

Built-in TV apps and consoles add another layer: the TV’s own audio processing. If the TV is set to external speakers but nothing is connected, Prime Video can appear silent.

  1. Set TV speakers as output — Choose TV Speakers in the TV sound menu and test Prime Video again.
  2. Set console audio to PCM — On PlayStation or Xbox, test with uncompressed stereo or PCM, then move to bitstream only after it works.
  3. Update the Prime Video app — Check for an app update on the TV or console store, then reboot the device.

Settings That Commonly Break Prime Audio

Prime Video can deliver multiple audio formats, and your setup may have several places that decide what to do with them. If audio fails after you add a soundbar, change cables, or enable ARC, use the table below to pin down the spot.

Where To Check What To Set What It Fixes
Streaming device audio PCM or Stereo (test) Silence from surround formats the TV can’t handle
TV eARC/ARC Auto, then Passthrough off Dropouts after pause, resume, or input change
Soundbar/receiver Direct mode or Auto decode Missing dialog, center channel, or full mute

Start by forcing stereo or PCM on the streaming device. If sound returns, you’ve confirmed a format problem. Then you can decide whether to stay on PCM, adjust the TV passthrough mode, or change the soundbar decode setting.

If you use a soundbar with ARC or eARC, also test with a different HDMI cable. Audio can fail on borderline cables even when video still looks perfect. A certified high-speed cable can stop random dropouts.

Network And Account Problems That Mute Streams

Sometimes the audio track never loads cleanly. The video starts, but the audio stream stalls or swaps tracks mid-play. Network hiccups, DNS errors, or a device that’s half-signed-in can cause this.

  1. Check your connection speed — Run a speed test on the same device, then try Prime Video again.
  2. Restart router and modem — Power them off for 30 seconds, then wait for a full reconnect.
  3. Switch Wi-Fi band — Move from 2.4 GHz to 5 GHz if available, or plug in Ethernet for a test.
  4. Sign out and sign back in — Log out of Prime Video, restart the app, then sign in again to refresh entitlement checks.

If audio fails only on one profile, check parental controls and device limits. Some households restrict certain audio languages or playback settings on kids profiles, which can lead to a bad default track. Try the main profile and test the same title.

  • Turn off data saver — On mobile, data saver modes can change stream selection and break audio tracks.
  • Disable VPN and proxy apps — Turn them off for a test, then reopen Prime Video and play the same scene.
  • Clear cached login tokens — Remove the app or clear storage on Android-based TVs when sign-in loops appear.

When To Reinstall, Reset, Or Contact Customer Service

If you’ve reached this point and prime video still has no sound, you’re down to corrupted app data, a device firmware bug, or a hardware path issue. The goal is to reset one layer at a time.

  1. Update the device firmware — Install system updates on the TV, streaming stick, or console, then reboot.
  2. Reinstall the Prime Video app — Remove it, restart the device, then install again so settings rebuild from scratch.
  3. Reset audio settings only — If your device has an audio reset option, use it before a full factory reset.
  4. Factory reset as last resort — Backup logins, then reset the device only if audio fails in multiple apps.

When you reach out to customer service, you’ll get faster help if you can share a few details. Write them down first so you don’t hunt through menus during the chat.

  • List your device model — Include the TV model and the streaming device model, plus any soundbar or receiver.
  • Note the audio path — Describe TV speakers, soundbar via ARC, receiver via HDMI, or optical cable.
  • Describe the pattern — Say whether the silence is on all titles or only certain ones, and if other apps play sound.
  • Record the exact title and time — Provide the movie or episode name and where the audio drops.

Play the same title with headphones on a phone. Sound there points to your TV setup; silence there points to the stream or account.

For readers who searched “amazon prime sound not working” and need a fast win, the highest success combo is a full device restart, a stereo or PCM test, then a clean reinstall of the app.
