Your Insignia TV has picture, but the audio is gone, too low, or playing through the wrong device. Current Insignia smart TVs sold through Best Buy use Fire TV software, so start with the Fire TV sound, app, and device menus before you assume the TV has failed. These fixes move from the fastest checks to the reset and service options that belong at the end.
Start with mute and volume
Use this when the TV suddenly goes silent across live TV, apps, or a connected device. It also applies when the sound is present but too low to hear.
Press Mute on the remote to make sure mute is off.
Press Volume Up several times.
If you use a soundbar, receiver, or paired speaker, raise the volume on that device too.
On many current Insignia Fire TV models, the TV's physical button is mainly for Power or Input, so use the remote or the paired audio device for volume.
Turn the TV speakers back on
This fixes the common case where the Insignia TV works, but its internal speakers were switched off because audio was routed somewhere else.
Open Settings, choose Display & Sounds, then select Audio Output. Go to TV Speakers and set it to On.
Test sound from the home screen, a streaming app, or the same input that was silent before.
If the TV still has no sound, check the selected audio output next, especially if a soundbar or receiver is connected.
Choose the audio output you actually use
Open Settings from the Fire TV home screen.
Select Display & Sounds.
Choose Audio Output.
There is no device list here. To hear the TV itself, set TV Speakers to On. To hear a soundbar or receiver instead, set TV Speakers to Off, set ARC Mode to Auto, and set Digital Audio Format to Auto, then switch that device to its own input.
Play something with known working audio before changing more settings.
Keep the soundbar or receiver on its matching TV, HDMI, or optical input while you test.
Fix soundbar and receiver format issues
Use this when the TV has picture but a soundbar or AV receiver stays silent.
- 1.Open Settings from the Fire TV home screen.
- 2.Go to Display & Sounds, then Audio Output.
- 3.Open Digital Audio Format.
- 4.Try PCM, Dolby Audio, Passthrough, or Auto until your audio device plays sound.
- 5.On older Insignia Fire TV menus, use the available PCM or Dolby Digital choice.
Restart the TV and audio gear
This fixes temporary Fire TV audio glitches and HDMI handshakes that get stuck.
Open Settings.
Select Device & Software, then choose Restart.
If your menu says My Fire TV, open that and choose Restart.
When the menus are sluggish, hold Play/Pause and Select together on the Fire TV remote for 3 to 5 seconds.
For a deeper power cycle, unplug the Insignia TV from the wall for at least 60 seconds.
Plug the TV back in, then power-cycle the soundbar or receiver too.
If HDMI sound still fails after the restart, disconnect and reconnect the HDMI cable after the power cycle.
Check HDMI ARC, optical, and headphone connections
The most common external-audio cause is a cable, port, or input mismatch between the TV and the soundbar or receiver.
For ARC or eARC, use whichever TV port is printed with eARC/ARC or ARC beside it, because the number is not the same on every Insignia. The F301 and F501 setup guides point to HDMI1 (eARC/ARC), while the QF Series guides for the NS-65UQFL26 and NS-75UQFL26 point to HDMI3 (eARC/ARC). Make sure the HDMI cable is fully seated at both ends.
Set the soundbar or receiver to the matching TV, HDMI, or Optical input.
If the silent source is a cable box or game console, try another HDMI cable or another TV port for that source.
Remove anything plugged into the TV headphone or audio-out jack. Insignia manuals state that connecting an analog speaker system or soundbar to the audio-out jack mutes the TV speakers.
Repair HDMI CEC and run diagnostics
Use these Fire TV tools when ARC or eARC audio control is the part that fails.
- 1.Open Settings, then choose Display & Sounds.
- 2.Select HDMI CEC Device Control and turn it Off.
- 3.Turn HDMI CEC Device Control back On.
- 4.Confirm the soundbar or receiver is on its HDMI ARC or eARC input.
- 5.Return to Display & Sounds and open Audio and Video Diagnostics if your TV has it, since Amazon notes the tool is not available on all Fire TV devices.
- 6.Select Troubleshoot Audio/Video Issues, choose No Audio, then follow the on-screen recommendations.
If sound is still wrong, go back to Display & Sounds, open Sound Settings, and use Reset to return your sound settings to the factory defaults when that option appears.
Clear app only sound problems
Open Settings.
Choose Applications.
Select Manage Installed Applications.
Pick the app that has no sound.
Choose Clear cache, then test the app again.
If the app is still silent, choose Clear data and sign back in.
When that does not help, select Uninstall, reinstall the app from the Fire TV app store, then restart the TV.
Use app troubleshooting only when system sounds or other apps still play normally.
Update, reset, or get service
Use this after the speaker, output, restart, cable, CEC, and app checks have all failed. The system update and reset options belong here because they affect the whole Fire TV setup.
Go to Settings, open My Fire TV or Device & Software, choose About, then select Check for System Update.
Use Amazon's official Fire TV software update information for software versions, and avoid third-party firmware downloads.
If sound is still missing from every app, input, TV speaker, headphone or analog output, optical output, and ARC output, open Device & Software or My Fire TV and choose Reset to Factory Defaults. This erases local settings and apps, so use it as the last software step.
Older Insignia Roku TV guides mention Roku speaker, restart, CEC, Headphone Mode, update, and app-removal menus. Current Insignia smart TVs in the Best Buy research are Fire TV models, so use the Fire TV audio output, HDMI CEC, app management, and update settings above.
When a reset and update do not restore any audio output, contact official Insignia service and support at 1-877-467-4289 or [email protected]. A TV with no audio from any source or output after these checks can have a speaker or audio-board hardware failure.
Frequently Asked Questions
Why does my Insignia TV have picture but no sound?
The usual causes are mute, TV speakers turned off, the wrong audio output selected, a soundbar or receiver format mismatch, an HDMI ARC or optical connection problem, or one app failing to play audio.
Which sound setting should I try first for a soundbar?
Start at Settings > Display & Sounds > Audio Output. There is no device list to pick from, so set TV Speakers to Off, set ARC Mode to Auto, and switch the soundbar or receiver to its own TV, HDMI, or Optical input. If the picture works but sound does not, open Digital Audio Format and try PCM, Dolby Audio, Passthrough, or Auto.
Why did my Insignia TV speakers stop after connecting external audio?
The TV may be routing sound to an external device, or the internal speakers may be muted by an analog audio-out connection. Turn TV Speakers back on in Audio Output and remove anything connected to the headphone or audio-out jack.
When should I factory reset an Insignia TV with no sound?
Use Reset to Factory Defaults only after checking mute, TV speakers, audio output, digital audio format, restart, cables, HDMI CEC, app cache or reinstall, and system updates. It erases local settings and apps.
