It is necessary to clear the TV cache in order to fix Philips Roku TVs no sound. First, by pressing the ‘Home’ button five times on the remote, then the ‘Up arrow’ button once, the ‘Rewind’ button twice, and the ‘Fast forward’ button four times, you should be taken to the Home dashboard.

There is a proven way to fix sound issues on Roku TVs by combining keys. I will show you in this guide several other proven ways to solve this issue.

1. Clear the Philips Roku TV cache

To resolve sound problems on your 65-inch, 50-inch, or 32-inch Philips Roku TV, you need to clear the remote’s cache by pressing a special combination of keys.

You can fix no sound on your Philips Roku TV by pressing the following key combinations:

  • Go to the Home dashboard first
  • Five times press the ‘Home’ button on your TV remote
  • Once, press the ‘Up arrow’ button on your remote
  • Double-click the ‘Rewind’ button
  • Lastly, press the ‘Fast forward’ button twice.

Your Philips Roku TV sound should be working again after a few seconds of shutting down and rebooting. You should be able to complete this entire process in 1-2 minutes.

2. Power Cycle Your TV

It is also possible to fix a Philips Roku TV that does not have sound by power cycling it. You can also clear your TV’s cache with this soft reset.

You can power cycle your Philips Roku TV by following these steps:

  • Disconnect the TV directly from the power outlet while it is on
  • Unplug it for 30 seconds
  • The TV can now be turned on by plugging it back into the power source

It should work without any delay, lag or intermittent cut outs once you turn your Roku Philips TV back on.

3. Switch Audio Output Mode

Another reason why Philips Roku TVs don’t have sound is that the audio output settings are incorrect. The Roku TV automatically detects your output mode (whether it’s an internal speaker or a sound bar) and supported modes by default. There are times, however, when this does not work, resulting in no sound.

Then, you must manually select a supported audio output mode. You can do this on your Philips Roku TV by following these steps:

  • Select Settings > Audio > S/PDIF and ARC
  • Put it on PCM-Stereo instead of ‘Auto detect’
  • Your Philips Roku TV should now have a working sound system

Otherwise, you can switch to Auto passthrough and then the other audio output options available one after another. PCM-Stereo or Auto passthrough should work for most Roku TV users using a sound bar.

4. Reset Audio/Picture Settings

Philips Roku TV audio settings can be messed up and result in several issues such as intermittent cutouts, audio that doesn’t sync with the picture, and even a complete lack of audio. Your audio settings will be reset to factory defaults in such cases.

If you are wondering, this does not refer to resetting your Roku device’s entire system; only the audio settings will be reset.

If you are experiencing audio problems on Philips Roku TV, go to Settings > System > Advanced System Settings > Factory Reset > Reset TV audio/picture settings. To reset the Roku TV audio settings, press the Play/Pause button three times. You should now be able to hear sound again. 

Default audio settings will be restored with a popup confirmation. If that resolves your Philips Roku TV’s sound issue, great. Continue with the next tip if this is not the case.

5. Switch Off Volume Mode

When your 65″, 50″, or 32″ Philips Roku TV’s sound doesn’t work, I ask you to turn off volume mode. This problem can also be resolved by switching the volume mode off.

When you switch off volume mode, you are not muting your Roku TV or turning off the volume. Roku TVs have a volume mode that enhances the sound experience but isn’t necessary to make sound work.

By using its options such as ‘Automatic Volume Leveling’, you’ll hear more consistent audio levels across various channels, preventing jarring interruptions when commercials come on or when you switch channels. It has a ‘Night Mode’ that allows you to watch late-night TV without disturbing others by lowering the volume level for louder scenes and raising it for quieter ones.

There are, however, some audio formats that do not support volume modes. 

It is possible to convert streaming formats with surround sound to stereo using volume modes, such as Dolby Digital, DTS, Dolby Digital Plus, and Dolby ATMOS. For this reason, you may need to turn off the volume mode on your Roku device if you are connected to an audio/video receiver (AVR) or sound bar.

To turn it off, follow these steps:

  • In order to do this, press the star (*) button on your Roku remote control.
  • Choose ‘Sound Settings’

NOTE: On some channels, the star (*) button does not lead to the audio menu shown below. This can be handled by switching to The Roku Channel and following the instructions. 

  • Turn off ‘Volume Mode’ by navigating to ‘Volume Mode’
  • You should be able to hear your Philips Roku TV sound as soon as you turn it off.

Similarly, if your Philips Roku TV audio only works on certain channels, such as Hulu, Netflix or Disney Plus, this will fix the problem.

6. Update Your Philips Roku TV Software

Check the Roku OS software version, and download any updates, if sound is still not working on your Philips Roku TV.

You can check and update your Roku software by following these steps:

  • On your Roku device remote, click the Home button
  • Go to Settings > System > System Update
  • To manually check for updates, click Check Now

The Roku device will automatically download and install any available software updates, and then reboot once they are installed.

To use this method, you must have an internet connection on your Roku device. In any case, you can try the manual update method.

7. Check HDMI & Internet Connections

Philips Roku TV audio issues can also be caused by a poor internet or HDMI connection.

Your Roku device’s internet connection must be checked first for signal strength and status.

  • See if it shows ‘Connected’ under Settings > Network > About. 
  • There is also a signal strength indicator, does it show ‘Poor’, ‘Good’, or ‘Excellent’?

Your Philips Roku TV may not be able to play sound if the network is not connected or the signal strength is poor. 

  • Click on Check Connection to complete the process.
  • It will now check your Wi-Fi/Wired connection as well as your Internet connection on your Roku device.
  • You should see a message stating ‘Connection check was successful’ once the check is complete

In the event that the connection check did not succeed, please check your network router and setup the connection again.

In addition, if you are using an Ethernet cable, make sure it is properly plugged in.

Lastly, make sure the HDMI cable is plugged in correctly.

Also, you can switch HDMI ports if the one you’re using isn’t working. Try another HDMI cable if possible.

8. Philips Roku TV factory reset

Resetting the Philips Roku TV to factory settings is another way to fix audio issues. You will lose all your installed apps and configurations, which is why I put it lower on the list.

To fix sound issues on a Philips Roku TV, follow these steps:

  • On the Roku remote, click the Home button
  • Select Settings from the menu
  • Go to System > Advanced system settings > Factory reset
  • Click on ‘OK’ after entering the code displayed on the TV

Alternatively, you can use the physical reset button on the TV to reset your Philips Roku TV without a remote. You can do that by following these steps:

  • Your Philips Roku TV has a physical reset button that can be pushed with a pin or any other tiny object.
  • If you find a reset button on your device, press it firmly and hold it for 10 to 20 seconds while it’s on. The Philips Roku TV logo will appear when the reset button is held down until it powers on again. After that, you can release the button.
  • The TV will reboot twice after the factory reset is complete and finally turn on.

You will now experience a brand new Roku device after restarting it. You will be able to hear the sound again once you complete the configuration.

9. Switch to Internal Speakers

Even if you are using the TV’s internal speakers, the audio issue may occur on your Philips Roku TV. A/V receivers, sound bars, surround sound systems, or any other type of audio equipment incorrectly set up can also cause problems.

If this happens, you can first check the sound output source by disconnecting the external sound system.

  • Audio sync should be fixed if you switch to internal speakers (whether it’s damaged or misconfigured). Check this while turning on the TV speaker. Settings > Audio > Speakers will show you that information
  • A Roku device issue, however, results from switching to the internal system despite switching to the internal system. Alternately, you can turn off the internal speaker by switching back to the sound bar.
  • You will need to switch the audio output to PCM-Stereo or Auto passthrough if you are experiencing this issue with your sound bar. S/PDIF and ARC settings can be found under Settings > Audio

10. Contact Roku Support

With all the tips above, you should have no lag, delay, echo, or intermittent drops with the sound on your Philips Roku TV.

You can contact Philips Roku for support if any audio problems persist or if you have any other issues setting it up. 1-866-309-5962 is the official contact number.
