You're finally sitting down. The kids are asleep, the popcorn is buttery, and you’ve just hit play on the latest episode of The Bear. Then, nothing. The video is crisp, Jeremy Allen White is looking intense, but there is absolutely no sound from Hulu. It’s maddening. You check your remote. You toggle the volume. Still, total silence. Honestly, this is one of the most common glitches on the platform, and while it feels like your TV is dying, it’s usually just a handshake error between the app and your hardware.
Sometimes the fix is stupidly simple. Other times, you’re digging into deep audio settings on a Roku or Firestick that you haven't touched since 2022.
The Quick Stuff You Probably Skipped
Before we get into the weeds of "Linear PCM" and "Bitstream" settings, let's look at the obvious culprits. Is your device muted? Seriously, check. I’ve seen people spend forty minutes troubleshooting their router when their toddler just hit the mute button on the side of the soundbar.
If that's not it, try the 10-second rule. Most Hulu audio bugs are caused by a temporary cache glitch. Close the app completely. Don’t just go back to the home screen—actually "Force Quit" it if you're on an Apple TV or Android box. Reopen it. If the audio returns, you’re golden. If not, the problem is likely a mismatch in how Hulu is trying to send sound to your speakers.
Why Hulu Specifically Struggles With Audio
Hulu isn't like Netflix or YouTube. It uses a very specific set of DRM (Digital Rights Management) protocols that can be finicky with HDMI cables. If you are getting no sound from Hulu but your Disney+ or Spotify works fine, it’s because Hulu is more sensitive to the "handshake" between your streaming device and your TV.
The Surround Sound Trap
Hulu often defaults to 5.1 surround sound. If you are listening through standard TV speakers and the app thinks you have a massive Bose home theater system, it might try to send the audio through a channel that doesn't exist. You’ll see the picture, but you won't hear a peep because the "center channel" (where the dialogue lives) is being sent to a speaker that isn't plugged in.
Go into your Hulu settings—right there in the app—and look for audio options. If you see an option for "Stereo" instead of "Surround Sound," click it. It’s a night and day difference for many users on older Vizio or Samsung TVs.
Hardware Gremlins: Cables and Connections
Let's talk about HDMI. Not all cables are created equal. If you're using an old HDMI 1.4 cable from a bin in your garage to stream 4K content, you're going to have bad luck. These cables can degrade. Sometimes they don't carry the audio signal properly while the video remains perfect.
- Unplug everything. Pull the HDMI out of the TV and the streaming box.
- Wait. Give it 30 seconds.
- Switch ports. If you’re in HDMI 1, try HDMI 2.
- Check the snugness. A loose cable is the primary cause of intermittent sound drops.
If you are using an Optical Cable for a legacy soundbar, those things are fragile. One tiny kink in the fiber optic line and your audio is toast. If you suspect the cable, swap it for a spare or try using the TV speakers just to see if the sound comes back.
Device-Specific Fixes That Actually Work
Every device has its own personality. A Firestick acts differently than a PlayStation 5.
For Roku Users: Roku has a weird setting called "Audio Mode." Go to Settings > Audio > Digital Output Format. If it’s set to "Auto," it might be guessing wrong. Change it to "Stereo" or "Custom" and select "Dolby Digital." This forces the Roku to stop trying to be clever and just play the sound.
For Firestick Users:
Amazon's devices love to update in the background. If an update stalled, your audio driver might be hanging. Go to Settings > Display & Sounds > Audio > Surround Sound. Switch from "Best Available" to "PCM." This tells the Firestick to decode the audio itself rather than asking your TV to do it. It’s a lifesaver for older Insignia or Toshiba Fire TVs.

For Web Browsers (Chrome/Safari):
If you have no sound from Hulu on a laptop, it’s almost always a tab issue or an extension.
- Check if the tab is muted (right-click the tab at the top).
- Disable "AdBlock Plus" or "uBlock Origin" temporarily. These extensions often mistake Hulu’s audio-triggering scripts for ads and kill them.
- Clear your browser cache. It sounds cliché, but old cookies can break the player.
The "Power Cycle" That Isn't Just Turning It Off
Most people think turning the TV off with the remote is a power cycle. It isn't. Modern TVs go into a "Sleep" or "Standby" mode. The bugs stay alive in the RAM.
To do a real power cycle:
Pull the plug from the wall. Let it sit there, cold and dead, for at least two full minutes. While it's unplugged, hold down the physical power button on the TV frame for 30 seconds. This drains the capacitors. Plug it back in. This "Cold Boot" forces the TV to reload its entire operating system, which usually clears out whatever was blocking the Hulu audio stream.
Check Your Internet Speed (Wait, Really?)
It sounds weird, right? Why would internet speed affect only the sound?
Hulu uses adaptive bitrate streaming. If your bandwidth dips, the app prioritizes the video stream to keep the picture moving, but it might drop the audio bitrate to near zero to compensate. If your Wi-Fi is struggling, you might get a "silent movie" effect. Run a speed test. If you’re getting less than 5 Mbps, that’s your culprit. Move your router closer or switch to a 5GHz band instead of 2.4GHz.
Software Updates and The "Nuke" Option
Sometimes, the app version you’re running is just buggy. App developers at Hulu release patches constantly.
Check your app store. Is there an update pending? If you're on the latest version and it's still silent, it's time to Uninstall and Reinstall. This is the "nuke" option. It wipes all local data and gives you a fresh start. You’ll have to log back in, which is a pain, but it fixes 90% of persistent software-side audio issues.
A Note on Public Beta Software
If you are running an iOS Beta or a preview build of Windows, Hulu's DRM might see your OS as "unauthorized." Hulu is very protective of its content. If it can’t verify that your audio output is secure, it simply won't send the signal. If you're on a beta, you might have to wait for an official release or roll back your OS.
Summary of Actionable Steps
Don't just give up and watch Netflix. You can fix this. Follow this specific sequence to get your sound back:
- Toggle the "Mute" and "Volume" on both your TV remote and your streaming device remote (they are often separate!).
- Check the Hulu App Settings and switch the audio from "Surround Sound" to "Stereo."
- Perform a Cold Boot by unplugging the TV and the streaming device from the wall for two minutes.
- Inspect the HDMI Cable for any damage and ensure it is pushed all the way into the port.
- Change the Device Audio Output in your system settings (Roku/Firestick/Apple TV) to "PCM" or "Stereo."
- Update or Reinstall the Hulu App to ensure you aren't running a corrupted version of the software.
- Check for Browser Extensions if you are on a PC or Mac, as ad-blockers are notorious for silencing Hulu.
If you’ve done all of this and you still have silence, the issue might be a hardware failure in your TV's mainboard or the soundbar's amplifier. Test a different app. If YouTube has sound but Hulu doesn't, it’s definitely a software or setting conflict. If nothing has sound, it’s time to look at your speakers.
