Amazon Prime Video No Sound on Smart TV: How to Fix

Amazon Prime Video no sound on your smart TV usually comes down to a wrong audio output or a glitch in the app—not a hardware failure. This guide will tell you the fastest fixes to restore audio, starting with the correct TV sound settings, Prime Video audio options, and device restarts. Follow the steps in order and you should get sound back quickly, whether you’re on Roku, Fire TV, Samsung, LG, or Android TV.

If Amazon Prime Video has no sound on your smart TV, restart the TV and the Prime Video app, then match your TV’s audio output (TV Speakers vs HDMI ARC/eARC vs Optical vs Bluetooth) to the device actually playing audio. After that, check Prime Video’s in-player audio track (and mute status), because “silent playback” is often caused by an audio-routing or track-selection mismatch rather than a TV hardware failure.

This fix is written for people using a smart TV app (not phone casting) who suddenly lost audio on Amazon Prime Video, especially when other apps still have sound or when the audio goes through a soundbar/AV receiver. It also applies when Prime Video is silent only during playback, while the TV home screen and menus sound normal. In 2026, this is still one of the most common failure patterns because HDMI ARC/eARC handshake and surround format negotiation can change how audio is delivered to the speakers—even if the video stream is fine.

Quick checks that fix most “no sound” cases

Restarting usually fixes the fastest layer first: the Prime Video app playback session. Then you confirm the TV is actually outputting sound to the correct destination by doing a quick sanity check with Prime playback.

Force-closing and reopening a streaming app can clear stuck playback state without changing TV settings.

A TV reboot also resets the HDMI ARC/eARC handshake, which is a frequent cause of app-specific audio dropouts.

If other apps still play audio, the fault is more likely within Prime Video’s session (track selection/codec) or audio handoff, not the TV speakers themselves.

– Restart the Prime Video app (force close, then reopen) and reboot your TV.

– Confirm Prime Video isn’t paused or set to a wrong audio mode; try another title or an episode where audio always worked before.

– If you use a soundbar/receiver, make sure the TV audio output is set to the correct device (e.g., HDMI ARC vs TV speakers).

If the problem clears after reboot, you’ve essentially confirmed this is a session/state issue. If it doesn’t, proceed to output routing and in-player track selection—those are the most common next causes.

Set the correct TV audio output (common culprit)

Your TV’s audio output setting must match the actual connection path (TV Speakers, HDMI ARC/eARC, Optical, or Bluetooth). If it doesn’t, Prime Video can appear silent even while the TV menu and other apps remain audible.

HDMI ARC and eARC both rely on correct “device control” and “digital audio out” configuration between TV and receiver/soundbar.

Changing “Digital audio out” modes (e.g., passthrough vs PCM/Auto) can help diagnose surround format negotiation problems.

When only one streaming app is affected, the issue is often codec/format negotiation for that app’s audio tracks.

– Open your TV audio settings and verify the output format/device: TV Speakers, HDMI ARC, eARC, Optical, or Bluetooth—choose the one that actually feeds your speakers.

– If your TV supports “Pass-through” / “Digital audio out,” temporarily switch to PCM/Auto to test whether a surround format negotiation is breaking audio.

– If the sound disappears only on Prime Video, compare settings when watching another app (YouTube/Netflix) to see what differs.

What to look for in your TV menus

Different TV brands label these options slightly differently, but the concepts are the same:

– TV Speakers = audio is generated and played by the TV itself.

– HDMI ARC / eARC = audio is sent to the soundbar/receiver over the HDMI connection.

– Optical (S/PDIF) = audio is sent via the Toslink/optical cable.

– Bluetooth = audio is sent wirelessly; some TVs reduce compatibility for multi-channel audio.

Because Prime Video can switch between stereo and surround audio tracks depending on title and playback conditions, a mismatch that still “works” for one app can fail for Prime when its audio format changes.

Prime Video app audio settings and track selection

Prime Video’s in-player audio track can be muted, set to an incompatible mode, or simply switch to a different audio language/format. Fixing the audio track inside the Prime Video player often resolves “video plays but sound doesn’t” without touching the rest of your system.

Prime Video playback includes an in-player audio track/language menu that can switch between stereo and surround formats.

If a Prime Video title supports multiple audio tracks, selecting a different track can bypass a codec negotiation problem.

Subtitles don’t mute audio by themselves; they’re mainly a diagnostic check that the player menus are responsive.

– In the Prime Video player, check the audio/“language” menu and select a different audio track (e.g., Stereo vs Surround, or another language).

– Toggle subtitles on/off as a quick test (not because subtitles cause sound loss, but to confirm you can access the in-player audio menu correctly).

– Clear the Prime Video app cache (and, if needed, reinstall) to fix corrupted playback metadata.

A practical diagnostic path (fast and reversible)

Start with the lowest-friction changes:

1. Pick a different episode or title that you know previously sounded fine.

2. In the Prime Video player, open the audio menu and switch from Surround to Stereo (or to another available language).

3. If you still get silence, clear Prime Video cache and retest.

From there, move back to system routing (HDMI/eARC/digital out) because the player menu may work but the TV/receiver is refusing the forwarded format.

HDMI/CEC/eARC and device handoff troubleshooting

HDMI ARC/eARC plus HDMI-CEC-style device control can break audio specifically for certain apps when the device “handshake” isn’t consistent. If Prime Video is silent but other apps work, this is a strong indicator of format negotiation or a control-session mismatch between your TV and soundbar/receiver.

ARC/eARC audio requires a stable connection and a consistent device control handshake between TV and audio equipment.

Reseating HDMI cables and cycling power resets the underlying negotiation that streaming apps rely on.

If Prime Video fails while other apps succeed, try changing the TV’s digital output format (e.g., passthrough vs PCM/Auto) as a codec compatibility test.

– If you route video through a receiver or use HDMI ARC/eARC, re-seat HDMI cables and cycle power on the TV + receiver/soundbar.

– Disable then re-enable HDMI-CEC/Anynet/BRAVIA Sync (wording depends on brand) to reset device control handshake.

– If audio works in other apps but not Prime Video, the issue can be codec/format negotiation—try changing the TV “Digital output” setting and test again.

Pros/cons: where to spend your time first

If you want a reliable order that minimizes disruption, use this decision framework:

Option	Pros	Cons
TV audio output match (TV Speakers vs ARC/eARC)	Usually fixes “no sound” immediately; reversible.	May temporarily change your surround setup.
Prime in-player audio track change (Stereo vs Surround)	Targets the app-level cause; preserves most TV settings.	Some titles may not offer multiple tracks.
Reset ARC/CEC handshake + HDMI cable reseat	Resolves negotiation/control issues affecting specific apps.	More time and requires powering hardware down.

If you rely on a complex home theater chain (TV → AVR → speakers), even a minor HDMI setting can affect audio delivery. The “PCM/Auto vs passthrough” switch is your quickest compatibility test without permanently changing your entire system.

What can go wrong (and how to avoid it)

Most “no sound” problems look simple, but a few common mistakes make them harder to diagnose. The key is to change one variable at a time and always retest Prime playback after each change.

Routing the TV output to the wrong destination (e.g., Optical vs HDMI ARC) can fully silence Prime even when the app UI appears normal.

Surround format passthrough can fail for certain apps or specific audio tracks, producing silence instead of a harmless fallback.

– Changing the wrong audio output can make it look like Prime has no sound (e.g., TV is set to Optical but speakers are on HDMI ARC).

– Surround settings may break audio for specific apps; if you’re using passthrough or a surround-only output, switch to Stereo/PCM as a diagnostic step.

– Factory resets and full app reinstalls are time-consuming—only do them after you’ve verified output routing and in-player audio track selection.

If your TV is managed by an ecosystem (for example, a home theater system with “auto” switching), start with the least disruptive steps. In my experience writing support-style guides, the fastest path is always: audio output match → Prime audio track change → PCM/Auto diagnostic—because it isolates routing vs playback format.

Verdict: the fastest reliable fix (and who should skip parts)

Start with: reboot TV → force-close Prime → confirm TV audio output → try another Prime title and switch Prime’s audio track. If you use HDMI ARC/eARC, prioritize the output/device handshake steps before deep resets.

When Prime Video has no sound but other apps work, matching the TV’s digital audio out format and device route usually resolves the issue quickly.

Switching from surround/passthrough to PCM/Auto is a practical diagnostic step for codec negotiation problems.

Skip the more disruptive steps (like clearing all TV settings or factory resetting) if you need immediate viewing or if your setup is managed by a home theater system you can’t easily power-cycle—take the gentler route first (app reset + output toggle), then escalate.

One quick reality check: if Prime Video is silent across multiple TVs on the same account (rare but possible) or you’re seeing “audio unavailable” messages on only some titles, the issue may be account-level entitlement, title availability, or DRM-related playback constraints—then the steps above may be limited.

FAQ

Why does Amazon Prime Video have no sound, but other apps work?

This usually points to the TV audio output being set for a different device/format, or Prime Video using an audio track/codec that doesn’t negotiate well with your current output settings. Start by matching audio output to your actual speaker connection and switching the in-player audio track.

Can subtitles affect sound on Prime Video?

Subtitles themselves shouldn’t remove audio, but checking the subtitle toggle helps confirm you can interact with the player’s menus (including audio track selection). If you can’t access audio options, the app may be stuck—restart the app and reboot the TV.

Does HDMI ARC/eARC cause Prime Video sound issues?

Yes—ARC/eARC handshake problems or surround format negotiation can affect specific apps. Test by changing the TV’s digital audio output mode (e.g., Auto/PCM vs passthrough) and power-cycling TV + soundbar/receiver.

Should I reinstall the Prime Video app to fix no sound?

Reinstalling can help if the app’s playback data is corrupted, but it’s best after you’ve checked audio output routing and in-player audio track selection. Clear cache first if your TV/app supports it, then reinstall as the next step.

Amazon Prime Video going silent on a smart TV is most often a routing mismatch (TV audio output set to the wrong target) or an app-level track/codec negotiation issue (Prime switches to an audio format your TV/receiver can’t forward correctly). By following the fastest order—reboot, confirm output path, switch Prime’s in-player audio track, then test PCM/Auto vs passthrough—you can resolve most “no sound” cases quickly without resorting to heavy resets.

Frequently Asked Questions

Why does Amazon Prime Video have no sound on my smart TV?

No audio on Amazon Prime Video is often caused by an audio output mismatch (TV vs. soundbar/receiver), an app-specific settings issue, or a temporary playback glitch. It can also be triggered by HDMI/ARC changes, TV firmware bugs, or using an unsupported audio format for your TV speakers. Start by checking whether the TV volume and mute are truly off, then test Prime Video with another title to confirm it’s not a specific episode or stream.

How can I fix Amazon Prime Video no sound on my smart TV quickly?

First, restart the Prime Video app and your smart TV, then fully power-cycle any connected audio devices (soundbar/AV receiver) to clear handshake issues. Next, open the Prime Video playback screen and check the audio track or “Subtitles & Audio” options for a correct language/format. Finally, go to your TV’s Audio settings and switch the output to the correct device (e.g., TV Speakers if you’re using them, or the right HDMI/ARC output if you’re using a sound system).

Which TV audio settings should I change to restore sound in Amazon Prime Video?

Set your smart TV’s audio output to match how you listen—choose TV Speakers for internal audio or HDMI ARC/eARC for a connected soundbar. If your TV supports it, try disabling “Digital/Pass-through” (like Dolby Digital/Bitstream) temporarily to see if Prime Video audio returns, since some combinations cause silence. Also ensure the TV’s Sound Mode and any “Surround/Enhancement” features aren’t overriding audio playback for apps.

What should I do if Amazon Prime Video works on other devices but has no sound on my smart TV?

This usually points to a smart TV audio routing or app configuration problem rather than your Prime Video account. Update the Amazon Prime Video app and your TV firmware, then clear the app cache/data (where available) to reset audio behavior. After that, test audio by switching the Prime Video output device in the TV settings and, if needed, reinstall the Prime Video app.

Best way to troubleshoot no audio on Amazon Prime Video when using a soundbar or receiver?

Confirm the soundbar/AV receiver is selected as the audio output in your TV settings and that HDMI ARC/eARC is connected to the correct ports. Power-cycle the TV and the audio device, then re-test Prime Video to ensure a fresh audio handshake. If the issue persists, try changing the receiver’s audio input mode (PCM vs Bitstream) and disable any audio “enhancements” that may conflict with Prime Video’s stream format.
