Amazon Prime Video Sound Not Working | Fast Audio Fix

Prime Video audio issues usually come from one of three places: the app, the device that’s playing it, or the audio chain between your TV and speakers. The fastest way to fix it is to isolate where sound breaks, then change the single setting that matches your symptom.

This article walks you through checks that bring sound back.

Amazon Prime Video Sound Not Working

First, confirm whether sound is broken only in Prime Video. Play a YouTube clip, a music app, or a local video. If everything is silent, your device audio is the issue. If other apps play fine, Prime Video is the likely problem.

Next, check where you expect audio to come from. Bluetooth headphones, a soundbar, or a receiver can silently steal output.

Now lock in the symptom. Total silence, missing voices, crackling, and delayed audio each point to a different fix. If you name the symptom first, you’ll change fewer settings.

1. Check mute and volume — Raise volume on the TV, soundbar, receiver, and the device running Prime Video.
2. Try another title — Test a different movie or episode, then test a trailer to rule out a title-specific stream.
3. Switch the audio track — Open the playback menu and pick a different language or audio option, then switch back.
4. Force-close Prime Video — Exit the app fully, reopen it, and start playback again.
5. Restart the whole chain — Power off TV and audio gear, unplug 30 seconds, then power up TV, then audio gear, then the player.

If you still have amazon prime video sound not working after that restart, use the symptom table next. It’s the quickest way to stop guessing.

Match The Symptom Before You Change Settings

Many “no sound” cases are format or routing problems. The table below helps you spot the pattern and run one confirming check.

Quick Prime Video Player Checks

Before you open your device menus, do two checks inside the player. These can fix silence caused by a stuck stream state.

1. Look for a muted player icon — Some devices keep a separate mute state in the on-screen player controls.
2. Pause and resume once — A short pause can re-sync playback and bring audio back after a bad start.

Once the player checks are done, move to device-specific fixes. TVs and streaming boxes come first because audio format mismatch shows up there most.

Fixing Prime Video Sound Not Working On Smart TVs

TV apps and streaming boxes sit in an audio chain that includes HDMI, ARC/eARC, soundbars, and receivers. If one device reports the wrong capability, Prime Video can output a format your chain can’t decode, which looks like silence.

Work from simplest to deeper settings. Change one thing, test a title, then move on only if you need to.

1. Confirm the TV output device — Make sure the TV is set to send audio to your soundbar or receiver, not the internal speakers.
2. Toggle ARC or eARC — Turn eARC off, test, then turn it back on.
3. Set digital audio output to PCM — Switch from Auto or Bitstream to PCM, then test Prime Video again.
4. Disable passthrough and advanced formats — Turn off passthrough, Dolby Digital Plus, and Atmos toggles one by one.
5. Try another HDMI port — Move the player or soundbar connection to a different HDMI port on the TV.
6. Swap the HDMI cable — A weak cable can keep video working while audio fails or drops.

If PCM brings sound back, you’ve confirmed a format mismatch. You can leave PCM on, or step back toward surround by enabling one format at a time and re-testing.

Streaming Box Audio Settings To Check

If you use a streaming box or console, check its audio settings too. These can override the TV choice and send a format your soundbar can’t decode.

1. Set the audio format to stereo — Choose PCM or Stereo as a test; if audio returns, try surround later.
2. Turn off audio passthrough — Passthrough can fail when the TV reports the wrong formats.
3. Disable Dolby Atmos output — If Atmos is forced on, some TVs drop audio on format switches.
4. Restart after changes — Reboot the box after changing audio output.

When 5.1 Causes Silent Dialogue

Silent voices with background sound often means Prime Video is sending multichannel audio and your chain is collapsing it badly.

1. Pick a stereo option during playback — If the title offers a stereo track, select it and test dialogue.
2. Keep the TV on PCM for a full test — Confirm voices return across multiple titles, not just one episode.
3. Power cycle audio gear — Restart the soundbar or receiver after format changes so it reads the new output.

If none of the format steps work, refresh the app state.

1. Update the Prime Video app — Install updates from the TV app store, then open Prime Video again.
2. Restart the TV or streaming device — Use the restart option in settings, or unplug for 30 seconds.
3. Reinstall Prime Video — Remove the app, restart, then install again and sign in.

Fix Prime Video Audio On Android And iPhone

Phones and tablets add a few traps: Bluetooth routing, low media volume, silent modes, and cast targets that still hold audio. Start with routing checks, then clean the app state.

1. Check Bluetooth output — Turn Bluetooth off, or pick the correct speaker in the phone’s output picker.
2. Raise media volume while playing — Press volume with a Prime Video title running so you adjust media, not ringtone.
3. Turn off silent and focus modes — Disable modes that can mute media audio on some devices.
4. Clear cache on Android — Clear Prime Video cache in App Info, then reopen and test.
5. Update and restart — Install updates for Prime Video and the OS, then reboot the phone.
6. Reinstall the app — Delete Prime Video, restart the phone, then reinstall to rebuild app data.

Fix Casting And Mirroring Audio Routing

When casting starts and stops, some phones keep audio pointed at the last target. Prime Video can play silently on the phone while the TV is muted, paused, or on a different input.

1. End casting everywhere — Stop casting from the phone and from the TV or dongle, then test playback.
2. Reconnect to the right target — If you want TV audio, cast again and confirm the TV input and volume.
3. Restart Wi-Fi gear if it keeps dropping — Reboot the router and test again with a fresh connection.

Fix Prime Video Sound On Windows And Mac Browsers

Browser playback has two volume layers: the site player and the computer’s system mixer. It’s common to have the tab muted or the browser volume lowered in the mixer while other apps still play sound.

Do mute checks first, then clear Prime Video site data. If sound still fails, check hardware acceleration and protected playback settings.

1. Unmute the tab and the player — Check the speaker icon in the Prime Video player, then check if the browser tab is muted.
2. Check the system mixer output — On Windows, open Volume Mixer and raise the browser volume; on Mac, confirm the active output device.
3. Reload the page — Refresh the Prime Video tab and start playback again.
4. Disable extensions briefly — Privacy and ad-blocking extensions can interfere with protected playback and audio.
5. Clear site data — Clear cookies and cache for Prime Video, sign in again, then test.

Hardware Acceleration And Protected Playback Checks

If video plays but audio fails, check settings tied to the graphics path and DRM playback. Do one change at a time, then restart the browser before testing again.

1. Toggle hardware acceleration — Turn it off, restart the browser, test, then revert if it makes playback worse.
2. Enable DRM-protected content — Allow protected playback in browser settings, then reload Prime Video.
3. Update the browser and reboot — Install the latest browser version, then restart the computer.

Also confirm your system isn’t sending audio to a dead output, like off Bluetooth headphones or a monitor with no speakers.

Fix Audio Sync And Random Dropouts

Not every sound issue is silence. If audio lags behind video, or drops for a second every few minutes, focus on processing and connection stability. The goal is to reduce extra audio processing steps and keep streaming steady.

If your TV or soundbar has a lip-sync adjustment slider, make small changes, test a scene with dialogue, then adjust again.

1. Turn off audio effects — Disable night mode, dialogue enhancement, and surround virtualization on the TV or soundbar.
2. Use a fixed audio format — Choose PCM or Dolby Digital instead of Auto, then re-test the same scene.
3. Disable match-content toggles — Turn off match frame rate or similar options, then test sync again.
4. Prefer Ethernet — Wired connections reduce jitter that can sound like stutter or brief dropouts.
5. Restart modem and router — A fresh connection can stop repeated packet loss during streaming.

Keep It Stable After You Fix It

Once audio is back, keep the setup steady so it doesn’t flip again during updates. Recurring cases come from Auto format settings, half-finished app updates, or devices that stay on for weeks without a restart.

If only one title is silent and others work, switch to another title and try the problem one later. A single stream can be glitchy without your hardware being at fault.

1. Stick with the stable format — If PCM is reliable, keep it and revisit bitstream only after you upgrade audio gear.
2. Restart after updates — After app, TV firmware, or OS updates, reboot the TV, box, or phone.
3. Power cycle weekly — Unplug the TV or streaming box for 30 seconds to clear stuck HDMI handshakes.
4. Simplify the HDMI chain — Use fewer switches and splitters, and keep cables short and secure.
5. Cross-test with another device — If amazon prime video sound not working returns, test on a phone or browser to confirm whether it’s device-specific.

If the same title is silent across devices, it points to a service-side issue. If only one device fails, focus on that device’s audio output, app state, and HDMI chain.
