Why Hulu Audio Out Of Sync?

There are four basic causes behind the audio issue.  Let’s check out each of them.

Slow Internet Connection

It’s possible that the issue is with your internet connection rather than the Hulu itself. The slow internet speed can affect Hulu broadcasting and cause audio delay.

The incorrect audio setting is a reason behind Hulu audio out of sync. Perhaps the audio settings are incorrect where you haven’t set the audio to Stereo or Normal.

Hardware Malfunction

Any hardware malfunction with your HDMI cable, HDMI port, or speakers can be another reason behind the Hulu sound out-of-sync problem.

Power Issues

If you’re having power issues, it may create problems with audio while watching Hulu. A simple power cycle or reboot can fix this issue. 

This method works in most cases even it has no link with the cause of the issue.

Once you’ve found out the reasons behind the problem, you can start fixing it with some quick solutions. You can apply the solutions according to the cause to get the best result. It’s also recommended to test the audio after each process.

1. Check Internet Connection

The first thing you can do is make sure that you’re running Hulu with a good internet connection. So, you can run a speed test to check whether you’ve the right internet speed to fix the Hulu audio out-of-sync problem.

But if the speed is slow, close all the background running apps to speed things up. Additionally, if you’re using WiFi, switch to an ethernet cable to boost up the speed. The wired connection is faster and more stable than a wireless one.

If it doesn’t solve your case, moving the router closer to the TV can come in handy. Place the router as close as to the TV where you’re streaming Hulu, connect the TV with WiFi again, and get faster speed.

2. Test Other Videos or Channels

If your Hulu audio is out of sync, play other videos (or channels if you’re watching Live TV) to check if they have the same issue. Due to technical glitches in the channel’s broadcasting, Hulu audio can not sync properly. 

If the issue affects all videos and channels, move on to the solution. But if not, the out-of-sync issue is with that particular broadcasting you’re watching. So, wait for a while until the technical issues are resolved or contact Hulu to fix it.

3. Check Audio Settings

Hulu audio out of sync might be caused by any misconfiguration in audio settings. To fix it, you can change the audio settings as follows.

For mobile or computer devices, locate the volume control at the bottom corner of the video you’re watching and ensure the volume is not muted or set too low.

Note: If you’re using Hulu on a Windows device, check out Microsoft’s Support site to get additional help on audio problems.

For TV-connected devices, go to Settings and select Stereo or Normal for audio. 

4. Adjust HDMI Cable

The Hulu audio out of sync can be related to HDMI cable malfunctioning. So, adjusting the HDMI cable can help you with troubleshooting.

If you’re using any TV-connected device for Hulu with HDMI cable, here’s what you can do:

  • Connect the cable to another port on the TV.
  • Connect the device to an HDMI port on another TV, if available.

(If these can sync the Hulu audio smoothly, the problem is within the HDMI port. You can contact the manufacturer to repair it.)

  • Reverse the end of the HDMI cable.
  • Use another HDMI cable and compare if the previous one is faulty or not.

(If your problem is solved after completing these two steps, the problem is with the HDMI cable. You can replace it with a brand new one.)

5. Test without External Speakers

If you’re using an external speaker and Hulu audio is out of sync, there can be compatibility issues between the speaker and the device you’re using for Hulu.

So, check whether Hulu supports surround sound for that device and the show you’re watching. If not, you need to switch the audio settings to Stereo on the device and test without external speakers.

6. Update Hulu

You can fix Hulu audio out-of-sync issue by updating the Hulu app to its latest version. An outdated app can cause certain audio problems. Hence, updating it can help with troubleshooting.

  • Clear cache and data from the device’s Settings menu.
  • Reset the TV power to fix your Hulu audio out of sync issue.
