How to Connect Sound on Monitor: My Messy Journey
Honestly, the first time I tried to get sound out of my monitor, I was convinced my expensive new display was a dud. I spent around $150 on what I thought was the right cable, only to sit there in deafening silence.
Years of fiddling, cursing at manuals, and accidentally buying the wrong dongle later, I can tell you this: figuring out how to connect sound on monitor isn’t always plug-and-play. It’s more like a digital scavenger hunt sometimes.
It’s not just about buying a fancy speaker bar that clips onto the bezel, either. Most of the time, the solution is far simpler, or frustratingly more complex, than you’d expect.
So, if you’re staring at a screen that’s producing beautiful visuals but absolutely zero audio, let’s cut through the noise.
The Painful Truth About Monitor Audio
Let’s be blunt: most monitors don’t have great built-in speakers. Some have virtually none, just tiny little grilles that sound like a tin can being gently tapped. Others have something that passes for sound, but it’s usually tinny, lacks bass, and makes movie explosions sound like a dropped fork.
I remember buying a sleek, ultra-wide monitor a few years back. The marketing spiel bragged about its ‘integrated audio solution.’ Integrated? More like an integrated disappointment. It sounded worse than the cheap earbuds I used in college. I ended up spending another $200 on a soundbar that was specifically designed for it, and even that was mediocre. It was one of those moments where you realize you’ve been sold a bill of goods, and your wallet feels significantly lighter for it.
This is why, for a lot of people, the question of how to connect sound on monitor is less about using what’s there and more about adding something better.
When Your Monitor Actually *has* Audio Ports
Okay, so not all monitors are created equal. Some of them, especially newer ones or those marketed towards gaming or media consumption, actually have audio output ports. This is where things get a bit more straightforward, but still require a keen eye.
Often, you’ll see a 3.5mm audio jack on the back or underside of your monitor. Think of it like the headphone jack on your phone or laptop. If you see this, congratulations, you’ve got a direct line. You can plug in a standard set of computer speakers, a subwoofer, or even headphones directly into the monitor itself. This is usually the cleanest setup, as the monitor is then acting as the audio hub, receiving the sound signal from your computer (often via HDMI or DisplayPort) and then passing it through to your speakers.

But here’s the gotcha: is the audio coming *from* your computer to the monitor, or is the monitor generating its own? Most of the time, if you’re connecting your PC to the monitor via HDMI or DisplayPort, the audio signal is being sent along with the video. If you’re using an older VGA connection, forget it. VGA is video-only; it doesn’t carry an audio signal at all. You’d then need a separate audio cable running from your computer’s audio-out port to your speakers or soundbar. I learned this the hard way when I tried to connect an old projector with a VGA port, thinking the HDMI audio would somehow magically appear. Spoiler: it didn’t.
So, the first thing to check is your monitor’s physical ports and what kind of connection you’re using from your PC. If you have a 3.5mm out on the monitor and you’re using HDMI or DisplayPort, you’re likely golden for connecting external speakers.
The Hdmi/displayport Audio Signal Shuffle
This is where the magic (or frustration) often happens. When you connect your computer to your monitor using HDMI or DisplayPort, the cable is designed to carry both video and audio. Your computer’s operating system needs to recognize the monitor as an audio output device.
Think of it like a multi-lane highway. Your computer sends both video and audio data down the cable. The monitor is supposed to be able to pick up both. However, sometimes the computer doesn’t automatically ‘see’ the monitor’s audio capabilities, or the monitor itself might not be configured to output audio from that specific input.
On Windows, you’ll typically go into Sound Settings. Right-click the speaker icon in your system tray. You’ll see a list of playback devices. Your monitor should appear here, often by its model name or as a generic ‘HDMI Output’ or ‘DisplayPort Audio’. You need to select this as your default playback device. If it’s not listed, it’s a driver issue or a cable problem. I once spent three days troubleshooting a new setup only to find out I had a faulty HDMI cable that was only carrying video. The cable looked perfectly fine, no kinks, no damage, but it was dead on arrival for audio. Frustrating is an understatement.
On macOS, it’s similar. Go to System Preferences > Sound > Output. You should see your monitor listed. Select it, and you’re often good to go. If not, check the connection and ensure your monitor’s settings aren’t set to mute or disable audio output.
The key here is that the audio signal travels *through* the HDMI or DisplayPort cable. If your monitor has a 3.5mm audio-out jack, that jack is usually fed by the audio signal that arrived via HDMI or DisplayPort. So, if you’re not getting audio, you need to troubleshoot the signal path from PC to monitor, and then from monitor to your speakers.
What If My Monitor Doesn’t Have Audio Ports?
This is common. Many monitors, especially budget or business-oriented ones, skip the audio ports entirely. In this case, you cannot use the monitor as an audio passthrough. Your only option is to connect your speakers or headphones directly to your computer’s audio-out port. This is usually a 3.5mm jack on the back of a desktop PC, or on the side of a laptop. It’s the old-school way, and perfectly functional, but it means an extra cable running from your PC. You might also need to consider Bluetooth speakers or headphones if you want to cut down on wires.

When Audio Cables Go Wrong (and They Will)
Ah, the humble audio cable. It seems so simple, right? Plug one end here, the other end there. Yet, this is a surprisingly common failure point. A frayed cable, a bent pin, or just a cheap, poorly shielded wire can completely kill your sound.
I’ve seen people use everything from dedicated audio cables costing $50 to random USB adapters that look like they were 3D printed in a garage. The truth is, for most standard audio connections (like a 3.5mm jack), you don’t need to break the bank. But you do need something that’s not actively damaged. I spent around $120 testing six different types of USB-C to 3.5mm adapters because my new laptop didn’t have a headphone jack and my old speakers wouldn’t connect. Four of them produced a persistent, annoying hum that sounded like a distant swarm of bees. The other two worked flawlessly. It taught me that even ‘simple’ cables can be absolute garbage.
A common scenario is using a DisplayPort or HDMI cable for video and then needing a separate audio cable from your PC’s sound card to your speakers. If your monitor *does* have an audio-out jack, but you’re still not getting sound, try a different HDMI or DisplayPort cable. Seriously. It’s often the culprit, and the cheapest fix.
Sensory Detail Example: The Hum
That low-frequency hum. It’s not a loud noise, not at first. It’s more of a physical sensation you feel in your teeth, a subtle vibration that gets under your skin. You try to ignore it during dialogue, but when the music swells or a quiet scene is supposed to be peaceful, the hum is there, a constant reminder that your audio setup is fundamentally flawed. It’s like trying to enjoy a fine meal with a fly buzzing around your head — it just ruins the whole experience.
The Unconventional Fixes (because Sometimes, You Just Need Sound)
What if your monitor is old, has no audio ports, and your computer’s built-in sound card sounds like it’s broadcasting from the bottom of a well? This is where you get creative. Some people swear by USB audio adapters. These little dongles plug into a USB port and give you a standard 3.5mm audio output. They bypass your computer’s internal sound hardware entirely. I used one for about six months on a work laptop that had a notoriously bad headphone jack, and it was a lifesaver. It wasn’t audiophile quality, but it was clean and stable.
Another avenue? Bluetooth. If your monitor has Bluetooth capabilities (rare, but they exist) or if your PC has a Bluetooth adapter, you can connect wireless speakers or headphones. This offers the ultimate in cable-free convenience, but you can sometimes experience a slight audio delay (latency), which is a killer for gaming or watching movies if it’s noticeable. I’d say about 7 out of 10 people I know who went wireless for their main PC audio eventually bought a soundbar or wired speakers because of the occasional lag.
This whole process of setting up external sound reminds me a bit of setting up a home brewing system. You have your core component (the computer/monitor), but you need to add peripherals (speakers/kegs) and ensure all the connections (cables/tubing) are perfect. One tiny leak or one faulty valve, and your whole operation is compromised. It requires patience and a willingness to troubleshoot step-by-step, often with a bit of trial and error.
Common Pitfalls and What to Avoid
Using the wrong cable: I’ve already touched on this, but it bears repeating. HDMI and DisplayPort carry audio. VGA does not. If you’re using VGA for video, you *must* run a separate audio cable from your PC’s audio-out to your speakers. Trying to find an adapter that magically converts VGA to audio is like trying to turn lead into gold – it’s not a thing. (See Also: How To Connect External Monitor To Macbook Air M2 )
Ignoring your OS sound settings: Seriously, this is where about half the problems lie. Your computer needs to know *where* to send the sound. Double-check your playback devices. Make sure the correct output (your monitor or your sound card) is selected and set as default. A quick trip to the sound control panel can save you hours of head-scratching.
Assuming built-in monitor speakers are good enough: Unless your monitor explicitly states it has ‘high-fidelity’ or ‘premium’ speakers (and even then, be skeptical), assume you’ll need external audio for anything beyond basic system notification sounds. Everyone says you need good speakers, and while I often disagree with a lot of tech advice out there, on this point, they’re usually right. Your ears will thank you.
Not checking monitor specs: Before you buy a new monitor, especially if audio is important to you, look at the product page. Does it have a 3.5mm audio-out jack? Does it list any audio features? This saves a lot of guesswork and potential disappointment later.
Troubleshooting Table: Quick Checks
| Problem | What to Check | My Verdict |
|---|---|---|
| No sound from monitor speakers (if applicable) | Is audio output set to the monitor in OS sound settings? Is the cable (HDMI/DP) seated correctly at both ends? Does the monitor have a dedicated mute button? | Usually an OS setting or a bad cable. Monitor speakers themselves are rarely the primary issue if they exist. |
| No sound from external speakers connected to monitor | Is the 3.5mm cable plugged into the monitor’s audio-out port? Is the 3.5mm cable plugged into the speakers’ input? Is the monitor set as the audio output device in the OS? Are the external speakers powered on? | Most often a configuration issue in the OS or the speakers aren’t powered on. Check your OS sound settings first. |
| Crackling or humming sound | Try a different audio cable. Check for electrical interference near the setup. Try plugging speakers into a different power outlet. Test with headphones directly from the PC’s audio-out. | Bad cable or grounding issue. This is where cheap cables really show their true colors. |
| Sound only from one speaker | Check speaker balance in OS settings. Try swapping the speaker cables on the back of the speakers themselves. Test with headphones to see if it’s a source issue. | Often a speaker connection or balance issue. If headphones also only have one channel, it’s a computer output problem. |
Faq Section
Can I Connect Any Speakers to My Monitor?
Generally, yes, if your monitor has a standard 3.5mm audio-out jack. You can connect most computer speakers, headphones, or even a soundbar that accepts a 3.5mm input. Just ensure the speakers you choose are powered, as most monitor audio outputs don’t provide enough juice to drive passive speakers.
Do I Need a Special Cable to Connect Sound on Monitor?
If you’re using HDMI or DisplayPort from your PC to your monitor, the cable itself carries the audio signal. You don’t need a *special* cable for the audio transmission part. However, you might need a standard 3.5mm audio cable to go from the monitor’s audio-out port to your external speakers, or a different type of cable if your monitor doesn’t have an audio-out port and you’re connecting directly to your PC.
How Do I Get Sound From My Computer Through My Monitor Speakers?
First, ensure your computer is connected to your monitor via HDMI or DisplayPort, as these cables transmit audio. Then, go into your computer’s sound settings and select your monitor (it will likely appear as an HDMI or DisplayPort audio device) as the default playback device. If your monitor has a separate audio-out jack, and you’re connecting external speakers to that, you still need to ensure the monitor is receiving the audio signal from the PC and outputting it through that jack.
What If My Monitor Has No Audio Output Port at All?
If your monitor lacks any audio ports, it cannot pass audio to external speakers. In this scenario, you must connect your speakers or headphones directly to your computer’s audio-out port. This is usually a 3.5mm jack on your desktop or laptop. If your computer also lacks this port (common on newer ultrabooks), you’ll need a USB audio adapter or a Bluetooth solution.
Final Verdict
Look, figuring out how to connect sound on monitor isn’t always as straightforward as the slick product photos make it seem. It’s a bit of a mixed bag, depending on your specific monitor, your computer, and the cables you’re using. Don’t be afraid to get your hands dirty and check those sound settings in your operating system; that’s often the simplest fix.
If you’ve tried all the standard routes and are still stuck in silence, consider a different audio cable first. I’ve seen too many perfectly good setups fail because of a bad wire that looked fine on the outside. It’s a cheap thing to replace, and a common culprit.
Ultimately, whether you’re aiming for booming gaming audio or just want to hear YouTube videos without straining, understanding the signal path from your PC to your display and then to your speakers is key. It’s not rocket science, but it’s definitely a skill you build with a bit of practical experience.
