Your Hulu app is experiencing audio issues when streaming due to incorrect sound settings, or the device you are using is experiencing issues.

Looking further into these issues, they could be due to;

Reason 1. Audio settings

If your internet connection is not good enough for Hulu to stream without having to buffer, this can interfere with the syncing of Hulu.

Hulu requires the following minimum speeds to be able to operate successfully;

Reason 3. Outdated app

Your Hulu app may be due to an update.

Hulu is continuously being updated to improve its performance and get rid of any possible errors that have transpired in the current version, like the audio not corresponding with the visuals on screen.

Reason 4. Full cache files

Cache files can also become corrupted, causing problems with the Hulu streaming service.

Reason 5. Problematic HDMI ports/cable

Current Hulu subscribers, who have had the Hulu out of sync issue, advise that a faulty HDMI port or cable can be a reason for this problem to occur when you are trying to watch a show on Hulu.

Keep in mind that if the Hulu server is experiencing problems, it can cause different types of issues to be showcased when users access their account, one of which is the audio out of sync from the visuals.
