It is one of the most frustrating moments in modern home theater. You sit down, fire up the latest binge-worthy show on Apple TV+, and realize you can’t turn the sound up. Or down. You press the buttons. Nothing. The little light on your TV doesn't even blink. Honestly, when your Apple TV remote won’t control volume, it feels like the whole "it just works" ecosystem has betrayed you.
But here is the thing: the remote itself usually isn't broken. It’s almost always a communication breakdown between the Siri Remote, the Apple TV box, and your television or soundbar. Sometimes it's a software glitch in tvOS, and other times it’s the physical line of sight for the infrared (IR) sensor.
The IR vs. HDMI-CEC Mess
To fix this, you have to understand how your remote talks to your speakers. It isn't magic.
Apple remotes use two primary methods for volume control. The first is HDMI-CEC. This stands for Consumer Electronics Control. It sends a signal through the HDMI cable to your TV, telling it to change the volume. If this is working, you don't even need to point the remote at the TV. It’s seamless.
The second method is IR (Infrared). This is old-school tech. The remote blasts a beam of light—invisible to your eyes—at a sensor on the front of your TV or receiver. If something is blocking that sensor, like a soundbar or a stack of books, your volume stays stuck.
If your Apple TV remote won’t control volume, your first move is checking the path. Look at your TV's bottom bezel. Is there a stray picture frame in the way? You'd be surprised how often a dusty sensor is the culprit.
Rebooting the Remote (Yes, the Remote)
Most people know how to restart a computer. Hardly anyone knows you can restart the Siri Remote itself. This is the "secret sauce" fix that solves about 80% of volume issues instantly.
Grab your remote. Hold down the TV/Control Center button (the one that looks like a computer screen) and the Volume Down button at the same time. Keep holding them. You need to wait about five or ten seconds. The status light on your Apple TV box will flash. Then, it will turn off and back on. On your TV screen, you’ll see a "Connection Lost" notification followed by "Connected."
Try the volume now.
It works because the remote's internal firmware occasionally hangs. It’s a tiny computer in your hand, and like any computer, it gets confused. Resetting the connection forces the remote to re-handshake with the Apple TV and re-establish the volume control protocol.
Diving into the tvOS Settings
If the hard reset didn't do the trick, the problem is likely buried in the settings menu. Apple hides these deeper than they probably should.
Go to Settings > Remotes and Devices > Volume Control.
What do you see there? If it says "Off," well, there’s your problem. Usually, you want this set to Auto. This allows the Apple TV to detect whether it should use HDMI-CEC or IR.
However, "Auto" isn't always smart. Sometimes it tries to use HDMI-CEC when your TV doesn't support it properly, or vice versa. Try toggling it. Switch it to TV via IR specifically. This forces the remote to act like a traditional universal remote.
Teaching the Remote New Tricks
If the standard options fail, you can actually "teach" your Apple TV remote the IR codes of your specific TV. This is a feature called Learn New Device.
- Go back to that Volume Control menu.
- Select "Learn New Device."
- Grab your original TV remote (the one that came with the television).
- Follow the on-screen prompts. You’ll hold the volume up button on the old remote until the progress bar fills, then do the same for volume down.
This bypasses all the HDMI-CEC handshake nonsense. It turns your Siri Remote into a dedicated IR blaster for your volume. It’s the most reliable way to ensure you never deal with this again, especially if you have an older Vizio or a picky Samsung unit.
When HDMI-CEC Goes Rogue
We need to talk about HDMI-CEC. It’s a great idea on paper. One cable to rule them all. But manufacturers are terrible at implementation. Samsung calls it Anynet+. Sony calls it Bravia Sync. LG calls it SimpLink.
If your Apple TV remote won’t control volume, it might be because your TV's CEC settings got toggled off during a firmware update. Check your TV's internal settings menu—not the Apple TV settings, but the ones for the TV hardware itself. Ensure CEC is enabled.
Also, check the HDMI port. Not all ports are created equal. On many TVs, only HDMI 1 or a port labeled (ARC/eARC) fully supports the bidirectional communication needed for volume control. If you plugged your Apple TV into a side port labeled "HDMI 4 (MHL)," you might be out of luck for CEC features.
Hardware Limitations and the "Dead Zone"
Sometimes the remote is just low on power.
We forget to charge these things. A Siri Remote with 5% battery might have enough juice to navigate menus over Bluetooth but lacks the power to fire the IR blaster reliably. Plug it into a USB-C or Lightning cable for thirty minutes. Check the battery level in Settings > Remotes and Devices. If it’s low, your IR signal strength drops significantly.
Then there’s the "ghost in the machine" issue: interference. Fluorescent lights or even some types of plasma screens can emit enough IR interference to drown out the remote. If you’ve recently moved your setup or changed your lighting, that could be the "why" behind your Apple TV remote won’t control volume.
The Soundbar Complication
If you use a Sonos, Bose, or Sonos soundbar, things get weirder. Many soundbars connect via Optical cable instead of HDMI. Optical cables cannot carry volume control commands.
In this scenario, your Apple TV remote must use IR. If your soundbar is tucked inside a cabinet or behind the TV, the IR signal won't reach it. You might need an IR repeater, or you'll have to rely on the "Learn New Device" method mentioned earlier to make sure the Siri Remote is sending the exact frequency the soundbar expects.
Why "Auto" Fails
Apple’s software tries to be too clever. When you set volume control to "Auto," the Apple TV polls the HDMI chain. If it sees a receiver, it tries to talk to the receiver. If it sees a TV, it talks to the TV.
But if you have a complicated setup—like an Apple TV plugged into a Hue Sync Box, which then goes into a Soundbar, which then goes into the TV—the "Auto" signal gets lost in the shuffle. The Apple TV might think it's talking to a device that isn't actually controlling the audio.
In these "chain" setups, manually locking the Volume Control setting to one specific device is the only way to maintain sanity. Don't let the Apple TV guess. Tell it exactly what to do.
Actionable Steps to Restore Control
Stop clicking the buttons hoping they'll magically start working. They won't. Instead, follow this specific order of operations to get your sound back.

- Clean the Remote and the TV Sensor: Use a microfiber cloth. A fingerprint on the tiny black window at the top of the remote can diffuse the IR beam enough to make it fail.
- The 10-Second Reset: Hold TV + Volume Down for 10 seconds. This is the most effective fix for modern Siri Remotes (the silver ones with the clickpad).
- Check for tvOS Updates: Go to Settings > System > Software Updates. Sometimes a bug in a beta or an older version of tvOS breaks the CEC handshake.
- Force IR Learning: If HDMI-CEC is being stubborn, go to Settings > Remotes and Devices > Volume Control > Learn New Device. Use your original TV remote to teach the Apple TV remote how to speak "Volume."
- Unplug the TV: This sounds like "IT 101," but unplugging your TV from the wall for 60 seconds clears the HDMI-CEC cache. This often resets the handshake when software toggles won't.
- Verify the Path: Ensure no physical objects are between your sitting position and the TV's IR receiver. If you have a soundbar blocking the bottom of the TV, you may need to raise the TV slightly.
If you’ve done all this and the Apple TV remote won’t control volume, it might be time to check the remote's health. Open the Camera app on your iPhone and point the Siri Remote at the lens while pressing the volume buttons. If you don't see a flickering light on the iPhone screen (which can see IR light that you can't), the IR transmitter in the remote might actually be dead. At that point, you’re looking at a replacement or using the Remote app on your iPhone as a permanent workaround.
