Quick Fixes for Hisense Roku TV Volume Issues
Before you reach for your toolbox or consider costly repairs, try these quick checks. Many volume problems stem from easy-to-solve adjustment or reset issues.
1. Check the TV’s Volume and Mute Settings
It sounds simple, but double-check that the volume isn’t muted or set very low. Sometimes, accidental remote presses or a stuck mute button can silence the TV.
- Step 1: Press the volume up button on your Hisense Roku TV remote.
- Step 2: Look for the on-screen volume indicator. If you see a mute symbol, press the mute button again to unmute.
2. Ensure TV Speakers Are Selected
The TV may default to external audio if you’ve previously used a soundbar or headphones.
- Step 1: Press the Home button, go to Settings > Audio.
- Step 2: Under “Speakers,” select “TV Speakers” and ensure they’re toggled ON.
3. Check Cable Connections
Loose HDMI or AV (audio/video) cables can disrupt the signal.
- Step 1: Turn off your TV and unplug it.
- Step 2: Remove and reinsert each cable securely, especially your HDMI and audio cables.
- Step 3: Power on the TV and test the sound.
If you’re currently using an Amazon Basics HDMI cable, try swapping it out for another one, as faulty cables are a common cause of audio loss.
4. Power Cycle Your TV
A simple reboot can clear minor glitches:
- Step 1: Turn off your Hisense Roku TV and unplug it from the power outlet.
- Step 2: Wait 60 seconds and plug it back in.
- Step 3: Turn it on and test the sound.
5. Update Your TV’s Software
Outdated firmware can cause unexpected volume malfunctions.
- Step 1: Go to Settings > System > System update.
- Step 2: Select “Check now” to search for and install updates.
- Step 3: After updating, restart your TV.

Advanced Troubleshooting When Quick Fixes Fail
If you’ve tried the basics and your TV volume is still misbehaving, it’s time for some advanced steps designed for persistent or more complex issues.
1. Reconfigure Audio Settings
Sometimes the TV is trying to output sound in a format your speakers or headset can’t process.
- Go to Settings > Audio.
- Look for “Audio Mode” and try toggling between “Auto,” “Stereo,” or “PCM.”
- Under “HDMI Audio Output,” try switching from “Auto” to “PCM” and test each option.
2. Hard Reset the Hisense Roku TV
A factory reset can solve software issues but will erase your settings and apps. Only do this if other fixes have failed.
- Open the Settings menu.
- Navigate to System > Advanced System Settings > Factory Reset.
- Follow the instructions and set up your TV again.
Be sure to reconnect your internet and sign in to streaming apps afterwards.
3. Test with a Different Input or App
Determine if the issue is with a particular streaming service, input device (like a game console), or app.
- Try playing content from multiple sources (HDMI, USB, built-in apps like Netflix or YouTube).
- See if the volume is affected on all sources or just one.
- If only one input or app is silent, reinstall that app or check that device’s audio settings.
4. Inspect External Sound Systems
If you use a soundbar or AV receiver, disconnect it and test the TV speakers directly. The soundbar or receiver could be set to a different input, muted, or experiencing hardware faults.
- Unplug the soundbar and any other external audio devices.
- Set the TV speakers as the audio output.
- If the TV speakers work, follow the manufacturer’s instructions to reset your soundbar and check compatibility.
5. Update or Repair Your Remote
Sometimes, faulty remote controls send the wrong signals to your TV. Replace the batteries or repair the remote according to the on-screen prompts in Settings > Remotes & Devices.
For replacements, consider upgrading to an official Roku voice remote, which often reliable than third-party options.
When to Suspect Hardware Failure
If none of the above steps restore your TV sound, consider a possible hardware issue inside the TV itself. This is less common but does happen, especially on older or heavily-used devices.
Indicators of Hardware Problems
- No sound even after factory reset and testing multiple inputs
- Crackling, distortion, or intermittent dropouts across different apps and sources
- Volume working only when applying physical pressure to the TV’s case (sign of loose internal wiring)
- Persistent “audio out” errors or audio delay not fixable through settings
At this point, you may need to contact Hisense customer support or a trusted television repair technician. If your TV is under warranty, you might be eligible for a free repair or replacement.
Preventing Future Volume Problems
Prevention is often easier than troubleshooting. Keeping your TV in good shape minimizes future disruptions.
- Protect from spills and dust: Speakers are sensitive; avoid liquid and regular dust buildup.
- Use surge protection: Voltage spikes can fry internal circuits, causing random audio failures.
- Avoid overheating: Ensure your TV has ample airflow, as overheating can shorten the lifespan of internal components.
- Keep software updated: Regular updates patch software bugs that can cause volume loss.
No one wants to struggle with TV volume issues when movie night or a gaming session is on the line. Thankfully, most Hisense Roku TV sound issues stem from minor, fixable problems you can resolve at home without special tools or expertise.
Run through the quick checks, rely on proven troubleshooting steps, and reference this guide when problems return. Don’t forget to maintain your TV and keep software up to date.
Should your issue turn out to be a rare hardware fault, reach out to Hisense or a qualified technician without delay.
FAQs on Hisense Roku TV Volume Not Working
Why does my Hisense Roku TV lose sound randomly?
This is usually caused by temporary software glitches, outdated firmware, or faulty HDMI connections.
Make sure all cables are firmly attached and run a software update check regularly. HDMI-CEC, which helps devices communicate automatically, can also cause audio to drop if there’s a conflict; try turning this feature off and on via Settings > System > Control other devices (CEC).
The TV volume works for streaming apps but not cable/satellite. Why?
This usually points to incorrect audio input settings or an issue with your external device. Check the audio settings on your cable or satellite box, and verify the TV’s input is configured to receive digital sound via “HDMI” or “AV,” depending on your setup. Replace cables if you suspect damage.
How do I fix distorted or crackling sound on my Hisense Roku TV?
Distorted audio can result from blown speakers, outdated software, or damaged cables.
Switch to different audio modes in Settings. Try playing audio through external speakers or a soundbar to identify whether the issue is in the TV’s speakers. If you notice distortion only at high volumes, this might indicate physical damage to the speakers.
There’s sound but the volume is very low, even at max setting. What now?
This usually means an audio mode mismatch. Try switching Audio Mode from “Auto” to “Stereo” or “PCM” in Settings > Audio. Disconnect all external audio devices and test internal speakers only.
Also, check individual app settings; some services (like Netflix) include their own volume controls.
Can a faulty remote control cause volume issues?
Absolutely. A remote with stuck buttons, low batteries, or internal faults might cause the TV volume to remain muted or stuck at a fixed level. Test with a different remote or use the Roku mobile app, which lets you control the TV via phone to see if sound returns.
My Hisense Roku TV won’t make sound through my headphones or soundbar.
Check that you’ve selected the correct audio output in the settings, and verify the headphones or soundbar are compatible with your model. If using Bluetooth, try unpairing and re-pairing. For wired devices, try a different port or cable to rule out hardware faults.
Does a factory reset erase all my apps and settings?
Yes, a hard (factory) reset wipes your installed apps, signed-in accounts, WiFi network settings, and any personal preferences. Only proceed if all other troubleshooting has failed and you’re ready to reconfigure the TV from scratch.
How do I contact Hisense support for persistent audio issues?
You can reach Hisense support online via their official support portal, or call the customer service number listed with your TV’s warranty documentation. Have your model and serial number ready for faster assistance.
