Roku's are amazing devices, and when they started building the sticks right into TVs, we instantly knew it was no-brainer that would simplify many home theater setups. But nothing's perfect, and some people have issues with their Phillips Roku TVs suddenly having no sound, no matter what they try.
A Phillips Roku TV may have no sound because it's muted, the volume is low, or audio settings aren't set properly. Start by restarting the TV before considering volume levels, clearing the TV's cache, and reviewing the audio output settings on the TV. Next, try updating the device and remote.
Fortunately, there are several more things you can do to fix the issue. We'll go in detail on the 8 tactics we recommend here, and after that we'll talk about the problem a little more before offering more details on audio management. Without further ado, let's fix that sound!
8 Ways To Fix A RokuTV With No Sound
So, if you have this Roku TV (on Amazon) issue, first let's try to just work through it by just doing these troubleshooting steps, in this order, without a bunch of troubleshooting to find the cause of the problem. First, try working through this list to brute-force fix the problem, but now that below this quick-reference table we're going to go into more detail and offer more advice for you if none of this works.
Oh – before we get too far – start by making sure your TV isn't muted! And power-cycle it at least once (though you probably already have) to make sure it wasn't some random glitch that goes away instantly.
Pro Tip: Many audio issues on a RokuTV are caused by the TV or Roku being on mute, or because the volume on external speakers is low. First, make sure the actual volume is turned up on every device in the chain.
| Troubleshooting Tactic | How To Implement |
|---|---|
| Clear the TV's Cache | Clear the TV cache: Go to Home dashboard, press ‘Home' button 5 times, ‘Up arrow' once, ‘Rewind' twice, ‘Fast forward' twice |
| Switch Audio Output Mode | Adjust audio output settings: Go to Settings > Audio > S/PDIF and ARC, switch from ‘Auto detect' to desired mode |
| Reset (Correct) Audio/Picture Settings | Reset audio settings to factory default: Go to Settings > System > Advanced System Settings > Factory Reset > Reset TV audio/picture settings |
| Switch Off ‘Volume Mode' | Turn off volume modes: Press star (*) button on Roku remote, select ‘Sound Settings', navigate to ‘Volume Mode' and switch it ‘Off' |
| Update Your Philips Roku TV Software | Check for and install software updates: Press Home button on Roku remote, select Settings > System > System Update, click ‘Check Now' |

| Reset Philips Roku TV to Factory Settings | Reset the TV to factory settings: Press Home button on Roku remote, select Settings > System > Advanced system settings > Factory reset |
| Switch to Internal Speakers | Use internal speakers: Adjust audio settings to switch to internal speakers |
Some of these fixes are a little more involved than others. Specifically, we'll offer a more detailed section below on the various audio settings you should check and a little more on how to actually do that.
Why Is This Happening? (Advanced Troubleshooting)
So, if none of that worked, you are now in a place of rolling up your sleeves and figuring out the problem. As we've mentioned, one of the most common causes of no sound on a Philips Roku TV is the TV being muted. Check the mute button on the remote or the TV itself to ensure it is not enabled. If the mute button is not the issue, then there may be a problem with the audio settings on your TV.
Another possible cause of no sound is a problem with the audio cables or connections. Check that all cables are properly connected and that there are no loose or damaged connections. If you're using external speakers, make sure they are properly connected to the TV, and that the TV knows it's supposed to send audio to them (in the audio settings)
If the audio settings and connections are not the issue, then there may be a problem with the Roku TV itself. In some cases, a software glitch or conflict between your TV and external speakers may cause no sound. If the TV is a bit older, it may just be at end of life. Expect your Roku TV to last 6-8 years.
It's also worth noting that sound issues may be related to specific apps. If you only experience no sound when using a specific app, then the issue may be with the app itself. Check the app's settings and try reinstalling it to see if this resolves the issue.
Checking the Roku TV's Audio Settings
There're several things we mean when we say “audio settings” in this context. So, have a look at these common “audio setting” mismatch issues that can cause a Roku TV with no sound, and go look at them in detail to see if they fix your issue:
- PCM Audio Format: If you're not getting any sound from your Philips Roku TV, you may need to adjust the audio settings. Go to Settings > Audio > Audio mode and select PCM-Stereo. This will ensure that the TV is using the right audio format.
- System Audio Control: If you're using an external audio device, make sure that the System Audio Control is turned on. This will allow your TV remote to control the volume of the external device. Go to Settings > System > Control other devices (CEC) > System audio control and turn it on. If you'd like to know a bit more about CEC and how it could be relevant here, check out our guide on the technology here.
- Volume Mode: If you're still not getting any sound from your Philips Roku TV, try changing the Volume Mode. Go to Settings > Audio > Volume mode and select Leveling. This will ensure that the TV's volume is consistent across all channels and programs.
- Audio Output Settings: If you're using an external audio device, make sure that the TV's audio output settings are set correctly. Go to Settings > Audio > Audio output and select the correct audio output. If you're not sure which audio output to select, consult the user manual for your external audio device.
Contacting Phillips or Roku Customer Support
If you have tried adjusting the audio settings on your Philips Roku TV and still have no sound, it might be time to contact customer support. If your TV is less than a year old, it's probably still under warranty! But it's not super clear if you should contact Roku or Phillips.
You can visit the Phillips support website to find valuable setup instructions and troubleshooting steps (as well as to get in touch with them). Alternatively, you can also visit the Roku support website to get help with your Philips Roku TV if you suspect the issue is in the software, not the hardware.
Either way, you'll benefit from just getting a clearer answer from those tech support options if what we've offered here hasn't solved your problem.
Hearing It All Clearly
By following the steps such as clearing the TV cache, adjusting audio settings, power cycling, and more, you can troubleshoot and fix the no sound problem on your Philips Roku TV. These simple yet effective solutions will help you get the most out of your entertainment system and ensure that every movie night or TV show marathon is filled with crystal-clear sound.
And be sure to expand that home theater sound with external speakers or a soundbar if you'd like – it's just one of the ways you can make your experience even better!
