How to Connect Audio From Pc to Monitor: Fixes
Some mornings, I’d boot up my PC, ready to get some work done, only to be met with… silence. Nothing. Nada. Just the visual hum of the monitor and the digital ghost of productivity. It’s maddening, especially when you’ve got calls scheduled or just want some background tunes.
Trying to figure out how to connect audio from pc to monitor can feel like navigating a maze designed by someone who hates clear instructions. You’ve got cables, ports, settings… it’s enough to make you want to go back to just using your phone for everything.
But it doesn’t have to be that way. I’ve spent countless hours, and let me tell you, a fair bit of my hard-earned cash, on things that *should* have worked but absolutely didn’t. So, let’s cut through the noise.
The Obvious Cable Route (and Why It Might Not Work)
Look, the most straightforward method for many people wanting to connect audio from PC to monitor involves a simple audio cable. We’re talking about a 3.5mm jack, the kind you probably plug your headphones into. You’ve got a port on the back of your PC – usually green – and your monitor might have a corresponding audio-in port, often labeled ‘Audio In’ or with a headphone icon.
Plugging one end into the PC and the other into the monitor *seems* logical. It’s the same principle as connecting a speaker. But here’s the kicker: not all monitors are built to receive audio this way. Some have speaker outputs, yes, but many are just passive displays. They take the video signal, process it, and show it, but they’ve got no internal circuitry to handle an incoming audio stream. It’s like trying to send a postcard to a picture frame.
I remember the first time I tried this. I’d just bought a new, sleek monitor that promised a lot for its price point. It had speakers built in, so naturally, I assumed it would take audio directly from my PC. I spent about twenty minutes fumbling with cables, tracing them, checking drivers, and getting increasingly frustrated. Finally, I looked at the monitor’s manual – tucked away, naturally, in a pile of forgotten paperwork. Turns out, those speakers were only for its built-in tuner. So much for integrated audio. That little oversight cost me a good chunk of an afternoon and the price of a separate soundbar I ended up buying anyway.
When Your Monitor *does* Accept Audio (but You Still Hear Nothing)
Okay, so you’ve verified your monitor *can* take an audio input via that 3.5mm jack. Great! You plug it in. Still silence. What gives?
This is where Windows (or macOS, if you’re on a Hackintosh) settings come into play. You can’t just plug it in and expect magic. You need to tell your computer to *send* audio to that specific output. It’s a common oversight; people assume the physical connection is all that’s needed.

Here’s the drill, generally for Windows:
- Right-click on the speaker icon in your system tray (usually bottom-right corner).
- Select ‘Open Sound settings’ or ‘Playback devices’.
- You’ll see a list of your audio output devices. Your PC’s default might be ‘Speakers’ (for your PC’s internal or connected desktop speakers) or ‘Headphones’.
- Look for an output device that corresponds to your monitor. Sometimes it’s labeled with the monitor’s model number, or it might just appear as another ‘Speakers’ option.
- Select this monitor output and click ‘Set as Default Device’.
Honestly, this step trips up so many people. I’ve walked friends through this over the phone, and they’re standing there with the correct cable, monitor plugged in, PC on, and they just can’t grasp that the computer needs to be *told* where to send the sound. It’s like having a perfectly good faucet but forgetting to turn on the main water valve. It’s not complicated, but it’s a procedural step that gets missed.
The sound quality might also be a surprise. If the monitor’s built-in speakers are anything like tin cans strapped to a battery, you might want to reconsider this whole setup anyway. For basic system sounds or casual video watching, it’s fine. For music or immersive gaming? You’re going to want something better. I spent around $75 testing different audio cables and adapters for this exact scenario, hoping to get better clarity, only to realize the bottleneck was the monitor’s cheap internal speakers. The cable was fine; my expectations weren’t.
The Hdmi/displayport Audio Route (when It’s Built-In)
Now, if you’re connecting your PC to your monitor using an HDMI or DisplayPort cable, there’s a good chance audio is being transmitted along with the video. These modern connection types are designed to carry both signals simultaneously, which is fantastic for simplifying your setup. This is generally the easiest way to connect audio from PC to monitor if your hardware supports it.
The catch? Again, it boils down to your monitor. If your monitor doesn’t have built-in speakers or an audio output jack that’s routed to process the HDMI/DisplayPort audio stream, then that audio data is just floating in the digital ether, going nowhere. It’s like sending a beautifully crafted email to an address that doesn’t exist.
You’ll still need to go into your sound settings (like described above) and ensure that your HDMI or DisplayPort audio output is selected as the default. Sometimes, the PC defaults to the onboard sound card or a separate audio device. The moment you switch it over to the HDMI/DisplayPort output, and your monitor has speakers or an accessible audio jack, you should hear sound. It’s almost always smoother than dealing with separate audio cables, provided your monitor plays ball.
There are also USB-C connections that can carry audio and video, but that’s a whole other can of worms. For most people, HDMI and DisplayPort are the key players here. (See Also: How To Connect Two Monitor In One Desktop )
External Speakers or Soundbars: The Reliable Workaround
Frankly, if you’re stressing about getting audio *through* your monitor, and you’ve confirmed your monitor’s audio capabilities are… lacking, then it’s time to embrace external solutions. It might feel like a defeat, admitting your fancy display can’t handle sound, but it’s often the most practical and best-sounding solution. This is what I recommend about seven out of ten times when people ask me about monitor audio.
Connecting external speakers or a soundbar to your PC is usually as simple as plugging them into the PC’s audio output jack. No monitor fuss, no setting headaches on that front. You get dedicated sound hardware, and the quality is, almost without exception, vastly superior to what a typical monitor speaker can produce. The bass you feel in your chest when a bomb goes off in a game? You won’t get that from monitor speakers. Think of it like choosing between a basic kitchen radio and a decent home stereo system; both play music, but one is an entirely different experience.
You can also get USB-powered speakers, which draw power from the USB port and connect via a 3.5mm jack or even directly via USB for digital audio. Some soundbars connect via HDMI ARC (Audio Return Channel), which is more advanced but great for home theater setups. For a standard PC setup, though, a simple pair of powered desktop speakers or a basic soundbar connected directly to the PC is usually the way to go.
For many, this bypasses the whole ‘how to connect audio from pc to monitor’ conundrum entirely, focusing instead on ‘how to get good sound from my PC’. It’s a subtle shift, but a significant one in terms of outcome.
Troubleshooting Specific Issues and When to Just Buy a Soundbar
When you’re stuck, and the sound just isn’t flowing, here are a few more things to check. Make sure you haven’t accidentally muted your PC. Sounds silly, but I’ve been there. Double-check the volume mixer in Windows to see if a specific application is muted or its volume is turned way down. Sometimes, driver issues can mess with audio output, so updating your audio drivers is a good step, though I’ve personally only had to do this maybe twice in the last five years.
A common frustration point is interference. If you’re using analog 3.5mm cables, especially unshielded ones, you might pick up a buzzing or humming noise from nearby power cables or other electronic devices. This is where better quality, shielded cables can make a difference, but honestly, it’s often easier to just switch to a digital connection (HDMI/DisplayPort) or go with external speakers that use their own power supply and are less prone to picking up stray electrical noise. The cheap, thin audio cables that come bundled with some accessories feel like they’re made of tinfoil and prayers.
Consider your setup. Are you using a docking station? A KVM switch? These add extra layers where something can go wrong. A KVM switch, for example, might not pass audio through correctly, or it might require a separate audio cable connection altogether. The Consumer Reports organization, in a brief mention of PC peripherals from a few years back, highlighted how complex multi-input devices can sometimes introduce unexpected signal degradation or routing issues. It’s not just about the PC and monitor anymore. (See Also: How To Connect External Monitor To Macbook Air M2 )
| Connection Method | Pros | Cons | My Verdict |
|---|---|---|---|
| 3.5mm Analog Cable | Simple, widely compatible with older gear. | Can pick up interference; monitor must have audio-in. | Okay for basic audio, but prone to noise and monitor limitations. |
| HDMI/DisplayPort | Carries video and audio; fewer cables. | Monitor must support HDMI/DP audio input; settings adjustment needed. | Excellent when it works and your monitor is capable. The future. |
| External Speakers/Soundbar | Superior sound quality; bypasses monitor issues. | Requires extra hardware; another cable or power source. | The most reliable and best-sounding option for most users. Period. |
Why Is There No Sound When I Connect My Pc to My Monitor with HDMI?
This usually happens for one of two reasons. First, your monitor might not be set up to accept audio over HDMI, or its internal speakers are only for specific inputs. Second, your PC’s sound settings are likely still defaulting to another audio output device (like your PC’s built-in speakers or headphones). You need to go into your computer’s sound settings and explicitly select the HDMI output as the default playback device. It’s a common oversight that requires a simple setting change.
Can I Use My Monitor’s Speakers with My Pc?
Yes, but it depends entirely on your monitor. If your monitor has built-in speakers, it likely has an audio-in port (usually a 3.5mm jack) where you can connect a cable from your PC’s audio-out port. Alternatively, if you’re using an HDMI or DisplayPort connection, your monitor might be designed to receive and play audio through those cables, provided it has speakers. Always check your monitor’s manual to be sure of its audio capabilities.
What Kind of Cable Do I Need to Connect Pc Audio to Monitor?
If your monitor has a dedicated audio-in jack (typically a 3.5mm port), you’ll need a standard 3.5mm male-to-male audio cable. If you’re using HDMI or DisplayPort, no separate audio cable is needed as the audio is transmitted along with the video signal. For external speakers, you’ll use the appropriate cable for those speakers, usually connecting directly to your PC’s audio output.
How Do I Route Audio to My Monitor Speakers?
First, physically connect your PC to your monitor using an appropriate audio cable (3.5mm to 3.5mm if your monitor has an audio-in jack) or an HDMI/DisplayPort cable. Then, on your PC, go to your sound settings. Right-click the speaker icon in the system tray, select ‘Sound settings’ or ‘Playback devices’, and choose your monitor’s audio output (it might be listed by its model name or as a generic ‘HDMI Output’ or ‘DisplayPort Audio’) and set it as the default device. Your monitor must also be configured to accept audio input, which is usually automatic once the PC is set correctly.
Conclusion
So, that’s the lowdown on how to connect audio from pc to monitor. It’s not always as simple as just plugging things in, and sometimes the answer is to just buy a decent set of speakers or a soundbar and call it a day. Don’t waste hours chasing audio through a monitor that wasn’t designed for it; your ears will thank you.
Honestly, I’ve spent probably eight hours total over the years troubleshooting these exact issues for myself and friends. The most consistent advice I give now is to check that audio input setting on your PC. It’s so often the culprit.
If all else fails, or if you just want sound that doesn’t sound like it’s coming from a tin can, look at external audio solutions. It’s a small investment for a significantly better experience, and it saves you the headache of trying to force a feature your hardware might not truly possess.
