You pressed the volume button on your Sony TV remote, expecting your soundbar to respond. Nothing happened. You tried again. Still nothing. This frustrating moment is more common than you might think, and it can turn movie night into a technical headache real fast.
Here’s some relief: this problem usually has a simple fix. Most of the time, you’re looking at connection hiccups, settings that got switched around, or compatibility issues between your devices. You don’t need to be a tech wizard to sort this out.
This guide will walk you through why your Sony TV stopped talking to your soundbar and show you exactly how to fix it. You’ll learn the common culprits behind this issue and get step-by-step solutions you can try right now.

Why Your Sony TV and Soundbar Aren’t Playing Nice
When your Sony TV refuses to control your soundbar, it means the communication link between these two devices has broken down. This connection typically works through HDMI-CEC (Consumer Electronics Control), which lets your TV remote control other connected devices without needing multiple remotes cluttering your coffee table.
Think of HDMI-CEC as a translator between your devices. Your TV sends commands through the HDMI cable, and your soundbar receives and follows those instructions. When this system fails, your soundbar basically stops listening to your TV’s commands.
Several things can interrupt this conversation. Sometimes the issue lives in your cable connections. Other times, your device settings have changed without you knowing. Your soundbar might have switched to a different input mode, or maybe a software update changed how your devices communicate.
If left unfixed, you’ll need to juggle multiple remotes every time you want to watch something. Volume adjustments become a two-step process. Your streaming experience loses its smoothness. Plus, you might miss out on features like automatic power-on and synchronized audio that make soundbars so convenient in the first place.
Sony TV Not Controlling Soundbar: Common Causes
Your Sony TV and soundbar can fall out of sync for several reasons. Most of these causes relate to how the devices communicate through HDMI or their internal settings. Let’s break down what typically goes wrong.
1. HDMI-CEC Disabled or Misconfigured
Your Sony TV uses a feature called Bravia Sync (Sony’s version of HDMI-CEC) to control connected devices. If this feature gets turned off, your TV simply can’t send commands to your soundbar anymore.
This happens more often than you’d expect. A software update might reset your settings. You might have accidentally turned it off while exploring your TV’s menu. Kids playing with the remote can also change settings without realizing it.
Many people don’t even know this setting exists until something stops working. Your soundbar probably has a similar setting on its end too. Both devices need their CEC features enabled for the system to work properly.
2. Wrong HDMI Port Connection
Not all HDMI ports on your TV are created equal. Most Sony TVs have a specific port labeled “ARC” or “eARC” (Audio Return Channel). This special port handles two-way communication between your TV and soundbar.
If your soundbar connects to a regular HDMI port instead of the ARC port, your TV can send video to the soundbar but can’t control it. The connection works partially, which makes troubleshooting confusing.
3. Faulty or Low-Quality HDMI Cable
Your HDMI cable does more than just carry picture and sound. It also transmits control signals between devices. A damaged cable or one that doesn’t meet proper specifications can pass audio through just fine while failing to carry those control commands.
Cheap cables from unknown brands often lack proper shielding. Over time, even good cables can develop internal breaks from repeated bending. You might not see any visible damage on the outside, but the internal wires could be compromised.
Sometimes the issue isn’t damage but compatibility. Older HDMI cables might not support the newer features your devices need. If you’re using a cable that came with a device from five years ago, it might not handle modern communication protocols.
4. Firmware Outdated on Either Device
Manufacturers constantly update their devices to fix bugs and improve compatibility. Your Sony TV or soundbar might be running old software that doesn’t communicate properly with the other device.
These updates often fix control issues that users reported. Your TV might have received an update that changed how it sends commands, but your soundbar is still expecting the old format.
5. Conflicting External Devices
If you have other devices connected to your TV, like a cable box, gaming console, or streaming stick, they might be interfering with the communication between your TV and soundbar. Multiple devices trying to use HDMI-CEC at once can create conflicts.
Some devices take priority in the control hierarchy. Your streaming device might be intercepting commands meant for your soundbar. This creates a messy situation where your TV remote controls the wrong device or doesn’t control anything at all.
Sony TV Not Controlling Soundbar: DIY Fixes
Getting your Sony TV and soundbar back in sync is usually straightforward once you know where to look. These fixes tackle the most common issues, starting with the simplest solutions and moving toward slightly more involved ones.
1. Enable Bravia Sync on Your Sony TV
Your first stop should be your TV’s settings menu. Press the Home button on your Sony remote and look for Settings. From there, find External Inputs or Watching TV (the exact name varies by model).
Look for an option called Bravia Sync Settings or HDMI Settings. Make sure Bravia Sync is turned on. You might also see a list of connected devices here. Your soundbar should appear if everything is connected properly.
After enabling this setting, your TV might take a moment to recognize connected devices. Give it about 30 seconds, then try adjusting the volume. If your soundbar responds, you’ve solved the problem. If not, keep your Bravia Sync enabled and move to the next fix.
2. Check Your HDMI Connections
Unplug the HDMI cable from your soundbar and look at your TV’s back panel. Find the port labeled HDMI ARC or HDMI eARC. It’s usually HDMI port 3 or 4 on Sony TVs, but check your specific model.
Plug your soundbar’s HDMI cable into this ARC port. Make sure the connection is snug. A loose cable can cause intermittent problems that drive you crazy because they work sometimes but not always.
While you’re at it, check the other end of the cable where it connects to your soundbar. That port should also be labeled ARC or HDMI OUT. Tighten that connection too. Sometimes a simple reconnection solves the issue by reestablishing the handshake between devices.
3. Replace or Test with a Different HDMI Cable
Swap out your current HDMI cable for a different one. If you don’t have a spare, borrow one from another device temporarily just to test. Look for cables labeled “High Speed HDMI” or “Premium High Speed HDMI.”
These certified cables support all the features your devices need, including ARC and CEC. You can find decent ones for under $15 at most electronics stores. Don’t fall for expensive cables with gold-plated connectors and fancy marketing. A $10 certified cable works just as well as a $50 one for this purpose.
After swapping cables, test your volume control again. If it works with the new cable, you’ve found your culprit. If not, at least you’ve eliminated one variable and can focus on other solutions.
4. Update Firmware on Both Devices
For your Sony TV, press Home on your remote, then go to Help or Settings. Look for System Software Update or Product Support. Select System Software Update and choose Check for System Software Updates.
If an update is available, follow the prompts to install it. Your TV will restart during this process. Don’t unplug anything while the update runs. This can take anywhere from five to twenty minutes depending on your internet speed and the update size.
For your soundbar, the update process varies by brand. Most soundbars from Sony, Samsung, or LG have a settings menu accessible through their remote. Look for a firmware or software update option. Some soundbars update through a companion app on your phone. Check your soundbar’s manual for specific instructions.
After both devices update, turn everything off for about 30 seconds. Power them back on and test the volume control. Fresh software often resolves communication problems that seemed mysterious before.
5. Disable CEC on Conflicting Devices
If you have a streaming stick, cable box, or gaming console connected to your TV, try temporarily unplugging them. Just pull their power cables for now. This helps you figure out if one of these devices is causing interference.
Test your soundbar control with these devices disconnected. If it works, plug them back in one at a time, testing after each one. This identifies which device creates the conflict.
Once you know the troublemaker, look through that device’s settings for HDMI-CEC options. It might be called something different depending on the brand. Roku calls it “1-touch play,” Samsung calls it “Anynet+,” and other brands have their own names. Disable CEC on that device while keeping it enabled on your TV and soundbar.
6. Perform a Power Cycle Reset
This simple step fixes more problems than you’d think. Turn off your TV and soundbar using their power buttons. Unplug both devices from the wall outlet. Not from each other, but from the actual power source.
Wait for about two minutes. This gives the devices time to fully discharge any residual power and clear their temporary memory. While you’re waiting, you can also disconnect and reconnect your HDMI cables to ensure fresh connections.
Plug everything back in. Turn on your soundbar first, let it fully boot up, then turn on your TV. This boot sequence helps the TV recognize the soundbar properly during startup. Test your volume control once both devices are fully on.
7. Contact a Professional Technician
If none of these fixes work, you might be dealing with a hardware problem inside your TV or soundbar. A failed HDMI port, damaged internal circuitry, or a defective CEC chip requires professional diagnosis and repair.
Contact Sony support or a qualified TV repair technician in your area. They have specialized testing equipment that can pinpoint exactly what’s wrong. Sometimes the fix is simple for a pro but impossible to diagnose at home. Better to get expert help than waste more time on a problem that needs professional tools or replacement parts.
Wrapping Up
Getting your Sony TV to control your soundbar again usually comes down to checking connections, enabling the right settings, or updating your software. Most fixes take just a few minutes and don’t require any special tools or technical knowledge.
Start with the simple solutions like checking your Bravia Sync settings and verifying your HDMI connections. These solve the majority of cases. If those don’t work, move through the other fixes systematically. One of them will almost certainly get your devices talking again, and you’ll be back to enjoying your shows with proper sound control.
