To restart your device: 

After restarting it successfully, unplug it from the power source and wait for some second before powering it on again. Restarting solves most of the issues with Roku. 

#2: Muffled Audio

The Mute function may be activated without your knowledge. If you experience muffling once in a while, ensure that you turn off the Mute function and adjust the volume on your TV. You should also check if you made the correct audio input connection, as this is often the cause of muffled sounds. 

TV connections and cables

The cables, including your HDMI input, should be snuggly connected to the right port. If all your connections are intact, then you should worry less. 

#3: Interrupted Audio

Interrupted audio usually has to do with the PCM stereo. If this happens:

#4: Out of Sync/Delayed Audio

Tips and Reminders

Most Roku audio issues are solved by restarting the device. If, for some reason, the issue persists, you may need to update the firmware or factory reset it. Let’s start with updating the firmware. 

Most updates happen automatically in the background, but you may find out that it’s not the case in yours. Therefore, you may need to update it manually. To do that:

The next option is to factory reset your Roku device. This returns your device to its default setting, so you will have to redownload your apps all over again. Our support team recommends this step if you exhaust all options.

Alternatively, you can skip the stress of following the steps above by using the physical reset button on the device. If these don’t still solve the issue, contact the Roku support team by going to the company’s support web page. 

If you are not a professional, you shouldn’t try opening up the stick or the TV to identify the problem. You could make matters worse and void the warranty, which leaves you in a more difficult situation. 


How do you unmute Roku?

Unmuting your Roku is as straightforward as turning off the Mute function and adjusting the volume on your TV. 

What causes the delayed sound?

If the video and audio are out of sync, you may likely experience delayed sound. This can be solved by going to Settings.
