Hisense Tv No Sound

Have you recently realized your Hisense TV has no sound? Don’t panic – you’re not alone. Many Hisense TV owners encounter sound issues like no audio, low volume, muffled or intermittent sound. Issues like Hisense Roku TV black screen can also occur.

The good news is, most Hisense TV sound problems can be fixed with simple troubleshooting steps. This comprehensive guide will walk you through all the potential causes and solutions to restore sound on your Hisense smart TV.

What’s Causing the Hisense TV Sound Issue

Before you can get audio working again, it helps to understand why your Hisense TV stopped outputting sound in the first place.

Here are the most common culprits behind Hisense TV sound problems:

  • The volume is muted or turned down completely.
  • Incorrect sound output settings are selected.
  • Outdated firmware version needs upgrading.
  • Faulty or loose HDMI cable connection.
  • Incompatible audio codec from source device.
  • Internal TV speakers are damaged or blocked.
  • Software bugs or glitches.

Finding the specific cause allows you to focus troubleshooting efforts and avoid wasting time.

Now let’s walk through the steps to diagnose and fix your Hisense TV’s sound.

Quick Fixes to Try First

Before digging into advanced troubleshooting, attempt these fast and easy fixes which resolve Hisense no sound issues over 80% of the time:

  • Check the mute button on your Hisense remote to make sure audio isn’t muted. Also try pressing volume up or using the buttons on your TV.
  • Power cycle the TV by unplugging from power for 60 seconds, then reconnect. This clears any temporary glitches.
  • Verify audio cables are securely inserted into inputs and not damaged. Try connecting different cables if available.
  • Reset devices like streaming sticks, Blu-ray players or game consoles attached to your Hisense TV.

Following these quick tips before moving onto more complex solutions will save you lots of time and effort.

Adjusting Your Hisense TV Sound Settings

One overlooked cause of sound problems on Hisense TVs are incorrect audio output configurations. Here’s how to access sound options and set them up properly:

  1. Using your remote, press the Menu button and select Sound.
  2. Under Audio Out/Output, choose TV Speakers or your external audio device like soundbar.
  3. Check volume levels, bass/treble, balance, surround effects are set optimally.
  4. For external speakers, adjust audio delay sync to match video.

If you have a Hisense Roku TV, the settings process is similar – just select Audio instead of Sound. Navigating to the appropriate menu and switching audio output fixes sound issues in over 20% of cases, so it’s worth checking.

Firmware Updates to Maintain Performance

Like all smart TVs, Hisense models receive periodic software updates to fix bugs, patch security flaws and improve performance.

If it’s been awhile since your last update, a firmware upgrade could resolve problems like:

  • No sound, audio dropping out
  • Apps crashing or freezing
  • Slow/unresponsive interface
  • Difficulty connecting devices
  • Failure to turn on/off

Here are the steps to update your Hisense TV firmware:

1. Using wifi or ethernet, connect your TV to the internet.

2. Go to Settings > Support > System Update.

3. Select Check Firmware Upgrade.

If an update is available, follow prompts to download and install. Updates require 15-20 minutes plus reboot time for Hisense Roku TV models not turning on.

Once the latest firmware finishes installing, check if sound issues are resolved.

Fixing Faulty HDMI Connections

Since HDMI cables transmit both video and sound signals, they frequently cause audio problems on Hisense TVs.

Issues like no sound, static, popping or cutting out noises while watching HDMI video sources can usually be fixed by:

  • Checking cable connections at both ends to ensure firmly seated
  • Trying different HDMI cables in case current one is faulty
  • Switching to an alternate HDMI input port on TV
  • Toggling source device that utilizes the HDMI connection
  • Verifying HDMI cable is HDMI ARC model if connecting sound system

Occasionally the port itself malfunctions, so attempting multiple cables and inputs determines if that is the case. Some models also display Hisense TV blinking red light when HDMI issues occur.

Understanding Supported Audio Formats

To automatically output sound properly, your media sources and content must be encoded with audio formats compatible with your Hisense television.

Most Hisense smart TVs support Dolby and DTS codecs like:

  • Dolby Digital / Dolby Digital Plus
  • Dolby TrueHD (Atmos)
  • DTS Digital Surround
  • DTS-HD Master Audio

If you connect an older DVD/Blu-ray player or stream audio in an unsupported format, you’ll get video but no audio.

Refer to your device manual for exact codec capabilities. Using incompatible codecs is an obscure but solvable reason for no sound problems.

Resetting Your Hisense TV to Factory Settings

If you’ve worked through other troubleshooting tips with no success, resetting the TV restores original audio configurations.

Just be aware factory reset erases all custom settings like wifi networks, installed apps, account logins and preferences.

On Hisense Android smart TVs:

  1. Go to Settings > Device PreferencesFactory Reset Hisense smart TVs
  2. Select Reset and confirm when prompted

For Hisense Roku TV reset process:

  1. Open Settings > System > Advanced Systems Settings > Factory Reset
  2. Enter parental pin code if enabled
  3. Choose Factory Reset Everything

Give your TV a few minutes to reboot – sound should return upon setup completion. If not, there may be a hardware problem needing professional service.

Connecting an External Sound System

Suppose you narrowed the no audio problem down to faulty internal Hisense TV speakers. Or perhaps you simply want audio quality better than basic built-in speakers provide.

In that case, plugging in an external soundbar or speaker set via HDMI ARC, optical, RCA or Bluetooth connections can restore lost sound.

Soundbars feature dedicated drivers and processing specifically for audio playback. Higher-end options add surround formats for an immersive listening experience.

Alternatively, you can connect bookshelf speakers, floor-standing tower speakers, AV receivers and more to your Hisense television. Just match required inputs/outputs between TV and audio gear.

The benefit is reliable, crisp sound and avoiding the cost to replace integrated speakers, which may require professional installation.

When Should I Call Hisense Support?

Exhausted all suggested troubleshooting techniques but Hisense TV still has sound problems? Reaching out to their customer support team should provide answers.

Contact Hisense phone assistance if:

  • Factory reset did not resolve sound issues
  • Speakers or boards damaged upon inspection
  • Physical damage inhibits TV functionality
  • Set is within 1 year warranty period

Phone support can diagnose issues through advanced tests before determining if your Hisense TV qualifies for free repair.

Additionally, live agents may suggest further steps specific to the model like factory resetting Hisense smart TVs.

If warranty expired or the problem looks unfixable, buying a standalone sound system or new TV like top-rated Vizio vs Hisense models may be wisest.
