How to Connect Speakers to Computer Monitor Audio in?
Got a new monitor with speakers, or maybe some decent desktop speakers gathering dust? You’re probably staring at a tangle of cables and wondering how to make them sing together. It seems simple enough, right? Plug this into that. But oh boy, have I been there, wrestling with audio ports that look identical and manuals written in hieroglyphics.
Figuring out how to connect speakers to computer monitor audio in can feel like a puzzle with missing pieces, especially when marketing hype tries to sell you fancy adapters you absolutely do not need. I remember my first attempt, convinced a glowing blue USB monstrosity was the key to better sound. Spoiler alert: it wasn’t.
After countless hours and more than a few head-scratching moments, I’ve learned that it’s usually far less complicated than you’d think. The trick is knowing which port is which and what cable actually does the job without costing you a fortune.
Finding the Right Ports: It’s Not Rocket Science, Mostly
Alright, let’s cut to the chase. Most of you are here because you’ve got a monitor with an audio-in port and a pair of speakers that need juice. The biggest hurdle, honestly, is just identifying these ports. They can be sneaky. You’ve got your standard 3.5mm jack – that little round hole that looks like where you’d plug in your headphones. This is your most common friend.
Then there are HDMI ports, DisplayPort, USB-C, and a whole alphabet soup of connectors on your graphics card and monitor. Rarely do these carry analog audio *out* from the monitor to external speakers. They’re usually for sending audio *to* the monitor (if it has built-in speakers) or carrying video signals. So, unless your monitor specifically boasts an audio output port, don’t even bother with those.
The key is looking for an audio *input* port on the monitor that matches the audio *output* on your computer, or vice versa, depending on how you want to route the sound. Sometimes, it’s a simple 3.5mm auxiliary cable. Other times, you might be looking for RCA connectors if your speakers are older or more beefy. I spent around $75 testing three different ‘universal audio adapters’ before realizing my cheap $10 aux cable would have worked perfectly the whole time. It’s infuriating when you realize how much you’ve been overthinking it.
The Anatomy of Your Speaker Connection
Your speakers, bless their little audio-producing hearts, usually have one of two common connection types for getting sound *in*: either a standard 3.5mm audio jack (like your headphones) or a pair of RCA connectors (those red and white ports). Sometimes, especially with more professional or studio-grade speakers, you might see XLR or TRS jacks, but for most desktop setups, it’s the former two.
The computer side of things is where it gets interesting. Your PC or laptop will almost certainly have a 3.5mm audio output jack. This is usually colored bright green. If you’re lucky, your graphics card might have an HDMI or DisplayPort that *can* carry audio, but remember, that’s usually for sending audio *to* a monitor or TV with built-in speakers, not necessarily for outputting to external speakers *through* your monitor.

So, the most straightforward method of how to connect speakers to computer monitor audio in, assuming your monitor has an audio-in port (and again, not all do!), is to connect the audio *output* from your computer directly to the audio *input* on your speakers. The monitor, in this scenario, is just acting as a visual display. Its audio-in port becomes relevant if you’re trying to use the monitor’s speakers, or if you’re routing sound *through* the monitor to speakers connected to the monitor itself.
Honestly, the advice I see everywhere about using complex digital-to-analog converters for a simple desktop setup? It’s often overkill. Unless you’re an audiophile with a dedicated sound system and an untreated room, the built-in DAC on your motherboard or sound card is usually perfectly adequate for getting sound from your PC to your speakers via a simple cable.
Hooking It Up: The Actual Steps
Let’s get practical. Assuming your monitor *does* have an audio-in port (check the back or sides; it’ll likely be a 3.5mm jack), here’s the dance:
- Locate your computer’s audio output. This is almost always a green 3.5mm jack on the back of your desktop tower, or on the side of a laptop.
- Find your speakers’ audio input. Look for a 3.5mm jack or RCA inputs on the back or bottom of your speakers.
- Grab the right cable. For 3.5mm to 3.5mm, it’s a standard auxiliary cable. For RCA, you’ll need a cable with a 3.5mm plug on one end and two RCA plugs (red and white) on the other.
- Connect your computer to your speakers. Plug one end of the cable into your computer’s green audio-out jack and the other end into your speakers’ audio-in jack.
- Connect your speakers to your monitor (if you *must*). Now, if you specifically want sound routed *through* the monitor and then to speakers connected to the monitor, this is where the monitor’s audio-in port comes in. You’d run a cable from your computer’s audio-out to the monitor’s audio-in. THEN, you’d run another cable from the monitor’s audio-out (if it has one, which is rarer) to your speakers. This setup is less common and often introduces unnecessary complexity. Most people just want sound from their PC, not through the monitor.
- Configure your sound settings. On your computer, go to your sound settings and make sure your speakers are selected as the default playback device. You might need to select the correct input on your monitor if it has multiple options.
The key thing to remember is that you’re generally connecting your computer’s audio *out* to your speakers’ audio *in*. The monitor’s role here is typically just displaying the video. If you’re trying to use the monitor’s built-in speakers, you’d connect your computer’s audio out to the monitor’s audio in (if it has one), and then select the monitor as your audio output device in your computer’s sound settings.
When the Monitor’s Audio Input Is Actually Useful
So, when is that audio-in port on your monitor actually a good idea? Frankly, it’s most useful if your monitor has built-in speakers and you want to use them. In that case, you connect your computer’s audio-out (the green 3.5mm jack) to the monitor’s audio-in (also likely a 3.5mm jack). Then, you go into your computer’s sound settings and select the monitor as the playback device. Easy peasy. This is how most people would connect speakers to computer monitor audio in if they’re using the monitor’s own speakers.
However, if you have *external* speakers that you want to use, and your monitor has both audio-in and audio-out ports, you *could* technically route your computer’s audio to the monitor’s audio-in, and then from the monitor’s audio-out to your external speakers. I’ve only ever done this out of sheer necessity, usually when the computer itself was lacking a dedicated audio-out port (a rare but infuriating situation). It adds an extra point of potential failure and sometimes a slight degradation in sound quality, akin to using a cheap extension cord when you could have plugged directly into the wall.
What If My Monitor Doesn’t Have an Audio Input?
If your monitor lacks an audio input, you simply connect your computer’s audio output directly to your external speakers. The monitor becomes irrelevant for audio in this setup, which is the most common and straightforward configuration for using external speakers with a PC.

Can I Use My Monitor Speakers and External Speakers at the Same Time?
Generally, no, not easily or without specialized software. Most operating systems are designed to output audio to a single device at a time. You’d have to manually switch between your monitor speakers and your external speakers in your sound settings, which can be a bit of a hassle if you do it often.
Do I Need a Special Cable to Connect Speakers to Monitor Audio in?
Usually, no. For most setups involving a 3.5mm audio-in port on the monitor and standard computer audio-out, a simple 3.5mm auxiliary cable (like the one you’d use for headphones) is all you need. If your speakers use RCA inputs, you’ll need a cable with a 3.5mm plug on one end and RCA plugs on the other.
The ‘sound Card vs. Monitor Audio’ Debate: My Two Cents
Everyone talks about sound cards like they’re the holy grail. And sure, a dedicated sound card can be fantastic if you’re a gamer who needs ultra-low latency or a musician recording audio. But for simply connecting speakers to computer monitor audio in for everyday use? It’s often total overkill.
Your motherboard has integrated audio, and it’s gotten remarkably good over the years. For most people, that’s more than enough. In fact, the audio processing on a decent motherboard is likely better than what’s crammed into a budget monitor’s audio circuitry. The idea that you *must* have a separate sound card for good desktop audio is, in my opinion, marketing smoke and mirrors for the average user. I spent $150 on a sound card years ago for my office PC, and honestly, the sound quality difference for just listening to podcasts and music was barely perceptible compared to the motherboard’s built-in audio. My mistake was believing the hype without testing it first.
When it comes to how to connect speakers to computer monitor audio in, prioritizing a clean signal path from your computer’s audio output to your speakers is usually the best bet. If your monitor has an audio-in port, it’s an option, but don’t feel like you *have* to use it if your computer can connect directly to your speakers.
| Connection Type | Pros | Cons | My Verdict |
|---|---|---|---|
| PC Audio Out to Speakers | Simplest, most direct path. Often best sound quality for budget setups. | Requires speakers with direct input. |
Recommended for most users. Clean, reliable, and avoids an extra device in the audio chain. |
| PC Audio Out to Monitor In, Monitor Out to Speakers | Useful if PC lacks direct audio out or you want to consolidate cables through the monitor. | Adds an extra step, potential for slight quality loss. Monitor must have both audio-in and audio-out. |
Use only when necessary. Generally more complicated than it needs to be unless you have no other choice. (See Also: How To Connect External Monitor To Macbook Air M2 ) |
| PC Audio Out to Monitor In (for monitor speakers) | Ideal for using a monitor’s built-in speakers. | Limited by monitor speaker quality. |
Perfect for monitor speakers. If your monitor has speakers, this is how you’d use them. |
Troubleshooting: When Silence Strikes
So, you’ve followed the steps, double-checked the cables, and still… nothing. Don’t panic. Most audio issues are surprisingly simple to fix. Firstly, check the volume levels. Yep, I’m serious. Both on your computer *and* on your speakers. Sometimes a dial gets bumped, or a digital slider gets nudged. I once spent an hour troubleshooting, convinced a cable was fried, only to find the volume knob on my soundbar was turned all the way down. It looked like a tiny, black hole of silence.
Secondly, ensure the correct playback device is selected in your operating system. Right-click the speaker icon in your taskbar (Windows) or check your Sound preferences (macOS). Make sure your desired output device (your speakers, or the monitor if you’re using its built-in sound) is set as the default. It sounds obvious, but it’s the most common culprit after basic volume checks. The Federal Communications Commission (FCC) has guidelines about audio device compatibility and interference, and while this isn’t usually a regulatory issue for basic setups, it highlights how important correct configuration is for proper function.
If you’re still stuck, try a different cable. Cables can go bad, especially cheaper ones. Swap out your auxiliary cable for a known-good one. If you’re using RCA connectors, try swapping those. Sometimes, one of the tiny pins inside the connector can break or bend, rendering it useless without any visible damage. Testing with a different cable is a quick way to rule out a faulty accessory.
Final Verdict
Look, the whole point of how to connect speakers to computer monitor audio in is to get sound from your computer to your ears without unnecessary fuss. Most of the time, this means a direct connection from your computer’s audio output to your speakers. The monitor’s audio-in port is primarily for its own speakers, or a secondary route if absolutely necessary.
Don’t get sucked into buying dozens of adapters or fancy cables unless you genuinely need them for a specific, high-end setup. For 99% of users, a simple auxiliary cable or an RCA cable will do the trick. Test the simplest solution first. It’s often the one that works.
So, there you have it. Connecting speakers to your computer monitor audio in, or more commonly, directly to your PC, boils down to identifying the right ports and using the right cable. Don’t overcomplicate it. Your computer’s audio output is usually the starting point, and your speakers are the destination.
If your monitor has speakers, use its audio-in port to get sound from your PC to the monitor. If you have external speakers, connecting them directly to your PC’s audio out is almost always the best and simplest approach. That monitor audio-in port? Think of it as a useful, but not always required, accessory.
Before you buy anything new, just unplug your current setup and try a simple aux cable from your PC’s green jack to your speakers. Nine times out of ten, that’s all you need. It’s like trying to fix a leaky faucet with a wrench before you call a plumber; start with the basics.
