You're sitting there, staring at the YouTube progress bar moving silently across the screen. You’ve checked the plug. You’ve toggled the volume. Everything looks fine. Your computer literally says the device is active, yet there is nothing but an eerie, frustrating silence hitting your ears. Dealing with headphones connected but no sound on pc feels like a personal betrayal by your hardware. It’s one of those tech glitches that shouldn't exist in 2026, yet here we are, still fighting with Windows audio bitrates and driver conflicts.
Honestly, it’s usually not a hardware death sentence. Most people immediately assume their expensive Sony WH-1000XM5s or their trusty Bose QuietComforts have finally kicked the bucket. They haven't. Usually, it’s just a software "handshake" that failed. Windows is notoriously bad at juggling multiple output devices, especially if you have a monitor with built-in speakers, a USB mic with a headphone jack, and a pair of Bluetooth buds all fighting for attention.
The Playback Device Identity Crisis
The most common reason you have your headphones connected but no sound on pc is simply that Windows is talking to the wrong room. You might see your headphones listed in the Bluetooth settings, but that doesn't mean the audio engine has actually switched the stream to them.
Right-click that little speaker icon in your system tray. Open "Sound settings." You’ll see a section titled "Choose where to play sound." It sounds insulting to suggest, but check it anyway. Sometimes, an update or a specific app like Zoom or Discord will hijack the default output and force it toward a device that isn't even plugged in. If you see "Realtek Audio" selected but you’re wearing a USB headset, that’s your culprit.
Windows 11 made this a bit more annoying by burying the old Control Panel interface, but you can still find the "More sound settings" link at the bottom of the page. This brings up the classic "Sound" window. Look for the green checkmark. If it’s on your monitor or your laptop speakers, right-click your headphones and select "Set as Default Device." While you're there, right-click them again and hit "Set as Default Communication Device." This ensures that your music and your frantic Discord calls both go to the same place.
The Exclusive Mode Problem
Ever noticed how some apps just refuse to share? There’s a setting called "Allow applications to take exclusive control of this device." It’s meant to reduce latency for high-end audio production or gaming, but it often causes the headphones connected but no sound on pc error when you switch between, say, a game and a web browser.

If Spotify works but your game doesn't, or vice versa, one app has likely put a "Do Not Disturb" sign on your sound card. You fix this in the same classic Sound Control Panel. Highlight your headphones, click Properties, and head to the Advanced tab. Uncheck both boxes under "Exclusive Mode." Hit apply. You might need to restart your browser or the specific app you're using, but this often clears the digital pipe.
What about the Audio Services?
Sometimes the "engine" of the car just isn't running. Windows has a specific background service called "Windows Audio" that manages everything you hear. If this service hangs, you get silence.
- Hit the Windows Key + R.
- Type
services.mscand slap Enter. - Scroll all the way down to "Windows Audio."
- If it says "Running," right-click it and select "Restart."
- If it’s not running, start it.
It’s a "have you tried turning it off and on again" move, but specifically for the software layer that handles sound. It works surprisingly often when the UI says everything is fine but the reality says otherwise.
The Bluetooth Bottleneck and Driver Rot
Bluetooth is a miracle when it works and a disaster when it doesn't. If you’re using wireless cans and experiencing headphones connected but no sound on pc, the issue might be the "Hands-Free Telephony" profile. Windows treats Bluetooth headphones as two separate devices: a high-quality stereo output for music and a low-quality mono output for calls. Sometimes it gets stuck in the latter but fails to actually pipe any audio through it.
Go to "Devices and Printers" in the Control Panel (the old one, search for it in the Start menu). Find your headphones, right-click them, and choose Properties. Under the "Services" tab, you'll see a list. Try unchecking "Hands-Free Telephony." This forces Windows to only see the device as a high-quality audio sink. Note that this will disable the built-in microphone on your headphones, but if you’re using a dedicated desktop mic anyway, this is a legendary fix for sound quality and connectivity issues.

Drivers are the other half of this headache. "Updating" through Windows Update is usually useless. If you have a gaming headset from Razer, SteelSeries, or Logitech, you absolutely must use their proprietary software (Synapse, GG, or G Hub). These companies use custom drivers that Windows often overwrites with "generic" versions that don't actually work. If you recently had a Windows update and suddenly your headphones connected but no sound on pc issue appeared, your driver was probably rolled back to a basic Microsoft version. Reinstall the manufacturer's software. It's annoying bloatware, sure, but it's often the only way to get the proprietary DAC (Digital-to-Analog Converter) in the headset to wake up.
Format Mismatches and Sample Rates
This is a bit more technical, but stay with me. Every audio device has a "Sample Rate" and "Bit Depth"—stuff like 24-bit, 48000Hz (Studio Quality). Some older headphones or cheap USB adapters cannot handle the ultra-high frequencies that Windows 11 defaults to.
If your sample rate is set higher than what your hardware can actually process, you’ll get silence. Go back to that Advanced tab in your headphone properties. Try dropping the format down to "16 bit, 44100 Hz (CD Quality)." If the sound suddenly pops back on, you’ve found the limit of your hardware. High-res audio is great, but "no audio" is worse.
Physical Reality Check
I know, I know. You checked the cable. But did you check the other end? If you’re using a front-panel jack on a PC case, those internal wires are notoriously flimsy. They can come loose from the motherboard inside the chassis. If you’re plugged into the front, try the green port on the back of the motherboard. If the back works and the front doesn't, your case's HD Audio header is likely disconnected or dead.
Also, look for a physical mute switch on the cable itself. We’ve all been there. You spend forty minutes debugging drivers only to realize your thumb bumped the mute slider on the inline controller. It happens to the best of us.

The "Ghost Device" Cleanup
Windows remembers every single thing you've ever plugged into it. Over years of use, you might have twenty different "Headphones" entries hidden in your system. This creates a mess in the registry.
You can use a tool like "Device Cleanup Tool" or simply go to Device Manager, click "View," and select "Show hidden devices." Look under "Sound, video and game controllers" and "Audio inputs and outputs." If you see greyed-out versions of your headphones, right-click and uninstall them. All of them. Unplug your headphones, restart the computer, and plug them back in. This forces Windows to create a fresh, clean "handshake" with the device.
Why Realtek is Sometimes the Enemy
Most motherboards use Realtek chips. Their "Audio Manager" or "Realtek Audio Console" software often has a setting called "Jack Detection." If this is enabled, it waits for a physical "click" in the port before it sends power. If your jack is slightly worn out, the sensor might not realize a plug is inside. In the Realtek settings, look for a folder icon or a gear icon and find the option to "Disable front panel jack detection." Ironically, disabling the detection often makes the port work again because it just sends the signal regardless of what the sensor thinks.
Actionable Steps to Fix Your Audio Now
Don't just click things randomly. Follow this sequence to narrow down the problem:
- Test on another device: Plug the headphones into your phone or a laptop. If they work there, your PC is the problem. If they don't, the headphones or the cable are dead.
- The "Default" Check: Use the
mmsys.cplcommand in the Run box to open the legacy Sound menu and ensure your device has the green checkmark. - The Format Test: Lower your bitrate to 16-bit/44.1kHz in the device properties to rule out hardware incompatibility.
- Disable Enhancements: In the properties menu, go to the "Enhancements" tab and check "Disable all enhancements." Sometimes "Bass Boost" or "Virtual Surround" crashes the audio driver.
- The Driver Reset: Uninstall the device from Device Manager, unplug, and let Windows rediscover it.
If you’ve gone through all of this and you still have headphones connected but no sound on pc, there is a high probability that the onboard audio chip on your motherboard has a localized failure. In that case, don't buy a new motherboard. Just buy a cheap USB-to-3.5mm DAC. It bypasses the internal sound card entirely and creates a new audio path. It’s a $15 fix for a problem that looks like it requires a $500 repair.
Usually, though, it’s just Windows being Windows. A quick restart of the "Windows Audio" service or a toggle of the "Default Device" setting is all it takes to bring the noise back. Stay calm, check the software layers first, and don't throw your headphones against the wall just yet.
