Why is Hulu audio out of sync after commercials?
Adverts are inserted into live streams, and the switch can leave sound and picture slightly apart. Restarting playback usually fixes it; if it happens on one channel every day, report it to Hulu.

How to fix Hulu audio that’s out of sync
Live TV and on-demand shows go out of sync for different reasons. Here is what to try for each, from the app to the TV.
If Hulu’s audio is out of sync, restart the show first: on live TV the sound often slips at an advert break and comes back when playback restarts. If it keeps happening, close and update the Hulu app, restart the device, and set its sound output to stereo or PCM. If every app on that TV is out of step, not just Hulu, the TV or soundbar is adding the delay and its AV sync setting is the real fix.
Hulu’s on-demand library and its live channels behave differently. People commonly report live TV drifting after commercials while recorded and on-demand shows play fine, which points to the live stream rather than your equipment. Whatever the cause, nothing outside Hulu can change its stream; what you control is the app and your devices. The streaming guide covers the same ideas for other apps.
How to fix Hulu sound that lags
Restart the show
Back out of the programme and start it again. On live TV, switch to another channel and back. This re-aligns sound and picture when an advert break caused the slip.
Reset the Hulu app
Close the app fully, check for an update, and restart the TV or streaming box. On Android TV and Fire TV, clearing the Hulu app’s cache in the apps settings is worth a try.
Simplify the sound
In your TV’s or box’s sound settings, switch the output from a surround format to stereo or PCM, then play the same show again.
Measure the rest
If other apps are off too, open the delay test on the TV or a laptop connected to it, press Start flash and beep, line it up, and enter the number in the TV’s AV sync setting.
Live TV or on demand?
Live TV
Live channels join feeds together, and adverts are inserted into them. Each join is a moment where sound and picture can fall out of step. If the slip appears after a break and a restart fixes it, the stream is the cause, and the only lasting fix is on Hulu’s side: report it through Hulu’s help centre with the channel and time.
On-demand shows
If one episode is always off on every device, that file was encoded out of step; report it. If every show is off on one TV but fine on your phone, the TV, its sound output or the Hulu app on it is the cause; work through the steps above.
Devices and sound systems
- Roku: Roku notes that sound settings which convert one audio format to another, and picture settings that add processing, can cause or worsen sync errors. Try stereo output and turn off heavy picture processing.
- Fire TV: AV Sync Tuning under Settings → Display & Sounds → Audio lets you line up a ball and a tone for the whole device.
- Smart TVs: look for game mode and an AV sync or lip-sync setting in the sound menu; the TV guide lists the names by brand.
- Soundbars and Bluetooth: a soundbar decoding surround sound or Bluetooth headphones add delay to every app; see Bluetooth audio delay.
Before you contact Hulu
- Note whether it is live TV or on demand, and which channel or show.
- Note the device and whether other apps on it are in sync.
- Try another device on the same account: if the show is fine there, the first device is the cause.
- Measure your TV’s own delay with the delay test; a figure near zero rules your setup out.
Questions about Hulu audio sync
Why are Hulu voices out of sync only on my TV?
Then the show is fine and your TV, its sound output or the app on it adds delay. Try stereo output, game mode and an app reset, then measure and set the TV’s AV sync.
Does reinstalling the Hulu app help?
Sometimes, especially after a TV or app update. Clearing the cache or reinstalling removes stored settings that can confuse playback.
Can I adjust the audio delay inside Hulu?
Streaming apps generally don’t offer an audio delay control; the adjustment lives in the TV, the streaming box or the soundbar.
Can sync.video fix Hulu?
No. Nothing outside Hulu can change its stream. sync.video can measure your TV’s own delay so you can set it correctly, which fixes the cases where your equipment is the cause.
