You have a picture, but no sound. Before you change audio settings or reset anything, it helps to work out where the sound is disappearing — inside one app, on the Fire TV Stick itself, across the HDMI connection, at the TV, or in a soundbar or receiver. This guide starts with the fastest safe checks, isolates the audio path, and keeps a factory reset as the very last option.
Fire TV menu names differ between a Fire TV Stick, a Fire TV Smart TV, and a dedicated Fire TV Soundbar, and TV audio settings differ by brand. Where a step depends on your specific device or television, this guide says so and points you to the setting to look for rather than promising one universal menu.
Quick answer
If the picture is fine but there is no sound, answer two questions first:
- Does it affect every app, or just one? Open a second app and try to play something. If only one app is silent, start with that app before changing TV or HDMI settings.
- Where should the sound come from — the TV’s own speakers, or a soundbar/receiver? The checks are different for each, so pick that branch before changing settings.
Then work in this order: confirm the TV isn’t muted and the volume is up, restart the Fire TV device without erasing apps, trace the audio path (TV speakers vs. external sound system, HDMI ARC/eARC, and HDMI-CEC), and only after that consider a software update. Use a factory reset as the last step, not the first.
If the screen is also blank or shows “no signal,” this is a different problem — see Fire Stick no signal. If sound is fine but the volume, mute, or power buttons on the remote do nothing, that is a remote/control problem, not an audio problem — see Fire Stick remote not working.
Use the right branch: a quick decision tree
Match your symptom to a branch before you start changing settings.
- Every app vs. one app. Test a second app. Every app is silent → keep reading (device / TV / audio-path problem). Only one app is silent → jump to When only one app has no sound.
- TV speakers vs. soundbar or receiver. Sound should come from the TV’s own speakers → work through the checks below and, in the audio-path step, confirm TV speakers are selected. Sound should come from a soundbar or receiver → go to Trace the audio path, where HDMI ARC/eARC and HDMI-CEC matter.
- No sound vs. a remote-button problem. No audio at all → continue here. Audio actually plays, but the remote’s volume/mute/power buttons don’t work → that’s control, not sound: see Fire Stick remote not working.
- No sound vs. audio delay. Silence → continue here. Sound plays but lags or leads the picture (lip-sync) → jump to Audio is delayed or out of sync.
Step 1 — Check mute, volume, and the input (start here)
These take a minute and rule out the simplest causes.
- Un-mute and turn the volume up. Check mute and volume on every remote in the chain: the Fire TV remote, the TV remote, and the soundbar/receiver remote if you have one. Amazon’s Fire TV audio guidance says to make sure the device isn’t muted and to press Volume Up.
- Confirm the TV is on the right input. Make sure the TV is showing the HDMI input the Fire TV Stick is plugged into (a picture from the Fire TV confirms this, but double-check if you switch inputs a lot).
- Try another HDMI input if your TV manual suggests one. If your TV’s manual identifies another suitable HDMI input, move the Fire TV Stick to it and select that input. Which ports carry audio and support features like ARC is set by the TV, so follow the TV maker’s guidance.
If sound comes back, you’re done. If not, continue.
Step 2 — Restart the Fire TV device (no apps erased)
A restart clears temporary glitches and does not delete your apps or sign you out.
- From the menu: open Settings, select My Fire TV, then select Restart. This is Amazon’s documented restart path for Fire TV devices, including the Fire TV Stick.
- By power: unplug the device’s power cable, wait a few seconds, then plug it back in. Amazon’s reboot guidance says to unplug and reconnect after about 3 seconds. For a soundbar, Amazon’s audio guidance suggests unplugging its power for roughly 30 seconds.
- On a Fire TV Smart TV, Amazon also documents a remote restart: press and hold the Play/Pause and Select buttons together for 3–5 seconds. This combination is documented for Fire TV Smart TVs; on a Fire TV Stick, use the Settings menu or the power method above.
Test sound again after the device restarts.
When only one app has no sound
If one app is silent while your other apps play sound, that app is the right place to start — though on its own it doesn’t rule the device out entirely. Begin with the app before changing TV or HDMI settings.
- Open the app again, then clear that app’s cache first. Amazon’s path is Settings → Applications → Manage Installed Applications → [the app] → Clear cache. Test again. Clearing the cache does not remove the app.
- Use Clear data only if the app still fails and you’re prepared to reset that app’s local settings — it may ask you to sign in again. Neither clearing the cache nor clearing data removes the app. For the full walkthrough, see How to clear cache on a Fire Stick.
- If several apps misbehave, or an app still fails after clearing its cache and data, work through Fire Stick apps not working.
If every app is silent, skip this section and trace the audio path next.
Trace the audio path: TV, HDMI, ARC/eARC, CEC, and sound systems
When every app is silent, decide where the sound is supposed to come from and check that path.
If sound should come from the TV’s own speakers
- On a Fire TV Smart TV, confirm the built-in speakers are enabled. Amazon’s path is Settings → Display & Audio → Audio Output, with TV Speakers set to On. On a Fire TV Stick, audio options live under Settings → Display & Audio; the exact sub-menu and labels can differ by device and software version, so look for the audio-output or Home Cinema settings there.
- On a Fire TV Smart TV, if you normally use external sound, switching TV Speakers back On is a quick way to confirm the Fire TV is producing audio at all.
If sound should come from a soundbar or receiver
Common things to check here are the HDMI port, whether HDMI-CEC is on, and where the TV is routing audio.
- Use the TV’s HDMI ARC or eARC port for the sound system. Amazon’s Fire TV Soundbar guidance says to connect the soundbar to an HDMI port on your TV that supports ARC or eARC. If you use a Fire TV Stick or Fire TV Cube as well, plug that streaming device into a non-ARC HDMI port so the ARC/eARC port stays free for the soundbar.
- Set the sound system to the right input. On a Fire TV Soundbar, Amazon says to set the input to HDMI using the Input button on the soundbar or its remote. For another brand of soundbar or receiver, select the TV/ARC/eARC input named in that device’s manual.
- Turn on HDMI-CEC on the TV. Amazon’s soundbar audio guidance says to set the HDMI-CEC function on your TV to On, and to set the TV’s Speakers / Audio Output setting to the soundbar or audio system. Amazon also notes you may need HDMI-CEC and HDMI ARC turned on to use some Fire TV features. CEC has a different name on each brand — for example Anynet+ (Samsung), SIMPLINK (LG), BRAVIA Sync (Sony), or simply CEC (Roku TVs and others) — and the exact menu path varies by brand, model, and TV software. Amazon maintains a per-brand guide, and if your brand isn’t listed there it advises checking your TV’s own manual.
- Confirm the TV is sending audio to the sound system. Amazon’s setup guidance says that if audio doesn’t route to the soundbar automatically, open the TV’s Speakers / Audio Output setting and make sure the soundbar or audio system is selected.
- Choose the audio format your equipment supports. On a Fire TV Smart TV, Amazon lists Auto, PCM, Dolby Digital, and Passthrough under Digital Audio Format (Settings → Display & Audio). Start with Auto unless your TV or sound-system manual gives a different setting; if the manufacturer specifically calls for PCM for a stereo-only connection, use PCM. On a Fire TV Stick, look for the equivalent audio-output option under Settings → Display & Audio; Amazon doesn’t publish a Stick-only page that lists every option by name.
- Power-cycle the sound system. Amazon’s soundbar audio guidance suggests disconnecting the HDMI cable from the TV and soundbar, unplugging the soundbar’s power for about 30 seconds, then reconnecting and trying again — and, if that fails, disconnecting other devices from the TV and connecting only the soundbar.
Once the soundbar is connected to the TV’s ARC or eARC input, Amazon notes you can usually use the TV remote to control its volume and power — a useful way to tell a sound problem apart from a remote-control one.
Step 3 — Check for a software update
Check for an available update before moving to a reset.
- Amazon’s path is Settings → My Fire TV (labelled Device & Software on some devices) → About → Check for System Update, then install any update offered.
- For a step-by-step walkthrough, see How to update a Fire Stick.
Restart and test sound again after any update installs.
Step 4 — Factory reset (last option only)
A factory reset should be your final step, after everything above. Amazon states that a factory reset removes your downloaded content, in-app purchases, and account information from the device, so you’ll set it up again from scratch.
Only if nothing else has restored sound, follow the full, safe procedure in How to reset a Fire Stick. Try one more restart and audio-path check before you commit to this.
When to contact a manufacturer
If, after the documented checks above and with a confirmed working source and input, sound is still missing on one piece of equipment, contact that maker rather than guessing:
- The TV — for HDMI-CEC/ARC menus, audio-output options, and which ports support ARC/eARC (these are set by the TV brand).
- The soundbar or AV receiver — if it powers on and shows the right input but stays silent on a known-good source.
- Amazon (Fire TV) — if the Fire TV device still has no audio on every app and output after the steps above, especially on more than one TV or input. The maker can advise on next steps or a replacement.
FAQ
Only one app has no sound — is my Fire Stick broken?
Usually the issue is in that app, so start there before touching TV or HDMI settings. Clear that app’s cache first (Settings → Applications → Manage Installed Applications → [app] → Clear cache), test again, and use Clear data only if it still fails (you may need to sign back in). See How to clear cache on a Fire Stick and, for stubborn cases, Fire Stick apps not working.
The volume buttons on my Fire TV remote don’t work, but sound still plays.
That’s a remote/control problem, not an audio problem. Because playback audio is present, focus on the remote-control setup instead — see Fire Stick remote not working.
My soundbar has no sound, but the TV speakers work.
Check the soundbar path specifically: connect the soundbar to the TV’s HDMI ARC/eARC port, set the soundbar to its HDMI input (or, for another brand, the input named in its manual), turn on HDMI-CEC on the TV, and set the TV’s Audio Output / Speakers setting to the soundbar. For the audio format on a Fire TV Smart TV, start with Auto and use PCM only if the sound system’s manual calls for it. Exact TV menu names vary by brand.
There’s no picture and no sound.
That’s likely a signal or connection problem rather than an audio-only fault. Start with Fire Stick no signal.
The audio is delayed or out of sync.
See Audio is delayed or out of sync below.
Audio is delayed or out of sync
If sound plays but doesn’t line up with the picture, this is a sync issue rather than missing audio:
- Restart the Fire TV device and the sound system, then re-test.
- On a Fire TV Smart TV using Bluetooth audio, look for Bluetooth Audio Sync under Settings → Display & Audio to align video and audio on the connected Bluetooth device.
- For an HDMI soundbar or receiver, use that device’s own lip-sync (audio-delay) control or its manual; menu names vary by maker.
