How to Get Audio to Come Through 2nd Monitor
Honestly, I thought it was just me. For years, whenever I plugged in a second monitor, the audio stubbornly stayed put, glued to the main display like a barnacle. It wasn’t until I was deep into setting up a triple-monitor gaming rig that I realized this wasn’t some cosmic joke; it was just a solvable tech problem I’d been ignoring for too long.
Trying to get audio to come through a 2nd monitor felt like trying to teach a cat to fetch. You know it’s *possible*, theoretically, but the execution is usually a mess. I’ve wasted countless hours fiddling with settings that seemed to do nothing, all while listening to game audio pipe out of my primary screen like some kind of digital monologue.
It turns out, it’s not about arcane magic or secret decoder rings; it’s usually just a few clicks or a quick driver update. This whole ordeal made me realize how many people probably just give up, accepting their audio fate instead of pushing for what they actually want.
The Hidden Audio Output: Why It’s Not Always Obvious
So, you’ve got your shiny new monitor hooked up, looking all sleek. Maybe it’s for gaming, maybe for more screen real estate for your spreadsheets (don’t judge), or perhaps you’re trying to finally get that dual-screen setup for editing photos without constantly alt-tabbing. But then… silence. Or rather, the *wrong* kind of sound. The audio is still belting out from your original speakers or headphones, and your second monitor is just a pretty, silent picture frame. This is the classic “audio confusion” scenario, and it’s infuriatingly common.
Think of your computer’s audio like a river. It has a source (your PC), and it can branch off into multiple streams (your speakers, headphones, HDMI output). The trick is telling the river *which* stream you want the water to flow through. Your operating system, primarily Windows or macOS, is the dam operator.
Windows 10/11 Audio Settings: Your First Stop
Alright, let’s get down to brass tacks. Most of the time, this whole rigmarole of how to get audio to come through 2nd monitor is solved right here, in the audio settings. If you’re on Windows, this is where you’ll spend 90% of your time troubleshooting. Right-click that little speaker icon down in your system tray. You know, the one that looks like a little speaker that’s been through a few too many system updates. A menu pops up. Look for ‘Sound settings’ or ‘Open Sound settings’.
This is your command center. You’ll see a dropdown menu under “Output devices” or “Choose your output device.” This is where Windows lists *everything* it thinks can play sound. Your built-in speakers, your headphones, any Bluetooth devices you’ve paired, and crucially, your monitor if it has built-in speakers or if it’s connected via HDMI or DisplayPort, which often carry audio signals.
Seven out of ten times, the solution is as simple as selecting your monitor from that list. If your monitor is showing up as an option (e.g., ‘Speakers (NVIDIA High Definition Audio)’ if you’re using an NVIDIA GPU, or ‘AMD HDMI Output’ for AMD), click it. Bam. Done. If it’s not there? Keep reading, because we’ve got more digging to do. I remember one particularly frustrating afternoon, I’d spent maybe $280 on a new 1440p monitor, only to have it be utterly silent, and it took me nearly an hour to find the correct output device in this very menu. The sheer relief when the game audio finally blasted from the monitor’s surprisingly decent built-in speakers was immense. (See Also: How To Put 144hz Monitor At 144hz )
The Hdmi/displayport Connection: Not Always Plug-and-Play Audio
This is where a lot of people get tripped up. You’ve plugged in your HDMI or DisplayPort cable, and the video is working beautifully. Fantastic. But audio? Not so much. The expectation is that if video travels down that cable, audio should too. And usually, it *does*. But sometimes, the driver doesn’t tell Windows that the audio is available, or Windows just decides to ignore it. It’s like having a brand new highway built, but the signposts telling you where to go are missing.
Here’s the kicker: not all HDMI ports on monitors are created equal. Some older or cheaper monitors might only accept video signals through their HDMI port, with audio being a separate, optional connection (usually a 3.5mm audio jack). Always check your monitor’s manual or specs online. Seriously, I’ve seen people spend hours troubleshooting, only to find out their monitor’s HDMI port doesn’t even support audio transmission. It’s a bit like buying a fancy sports car and then wondering why the trunk doesn’t open – you just didn’t check the features list.
If your monitor *does* support audio over HDMI or DisplayPort, and it’s not showing up in Windows sound settings, the next logical step is checking your graphics card drivers. Outdated or corrupt graphics drivers are notorious for causing all sorts of display and audio issues. NVIDIA, AMD, and Intel all offer free driver downloads from their websites. Go to their respective support pages, find your graphics card model, and download the latest stable driver package. Sometimes, a clean install is even better – there’s usually an option in the installer to do this. This process took me about twenty minutes on my rig last month when I was fiddling with a new GPU and suddenly lost all audio through my main monitor for an hour. A quick driver reinstall sorted it right out.
When Your Monitor Doesn’t Play Nice: Sound Card Workarounds
What if your monitor genuinely has no audio capabilities, or the HDMI/DisplayPort audio is just being a stubborn mule? This is where you have to get a bit creative, and honestly, it’s where things start to feel less elegant. My first dual-monitor audio headache involved a monitor that was only about $150 at the time, and it was crystal clear it wasn’t going to do audio. My solution? A cheap external speaker system that I plugged directly into my computer’s sound card, then ran the cable to the desk where the second monitor sat.
This is still a viable, albeit slightly clunky, method. You can buy small, inexpensive computer speakers or even a soundbar that connects via a 3.5mm audio jack. You then select *that* as your audio output device in Windows. The catch is, the audio is no longer coming directly *from* the monitor’s (non-existent) speakers, but rather from a separate device positioned near it. It’s not ideal if you’re aiming for a super clean setup, but it works. For about $40, I got a decent set of Logitech speakers that made my second monitor experience so much better for editing work, even if it meant one more cable to manage.
Another option, if you’re feeling a bit more adventurous and have a PC with an available PCIe slot, is to install a dedicated sound card. These offer superior audio quality and a wealth of connection options. However, for the specific problem of getting audio to a second monitor, this is probably overkill unless you’re also an audiophile or experiencing broader audio issues. For most people, a simple 3.5mm connection to external speakers is the most straightforward workaround when the monitor itself isn’t cooperating.
Macos Audio Settings: A Different Vibe
Okay, so you’re a Mac person. The whole process is generally smoother on macOS, but there are still potential hiccups. Similar to Windows, you’ll be digging into system preferences. Click the Apple menu in the top-left corner, then select ‘System Settings’ (or ‘System Preferences’ on older macOS versions). Look for the ‘Sound’ icon. Click it. (See Also: How To Switch An Acer Monitor To Hdmi )
In the Sound settings, you’ll see tabs for ‘Output’, ‘Input’, and ‘Sound Effects’. Click on the ‘Output’ tab. Just like Windows, macOS lists all available audio devices. If your monitor is connected via HDMI or DisplayPort and supports audio, it *should* appear in this list. Select it. Done. It’s often that simple.
However, if your monitor isn’t showing up, it could be a driver issue with your graphics card (even on a Mac, external GPUs or specific driver configurations can matter) or, again, the monitor’s HDMI/DisplayPort simply not transmitting audio. You might also have a conflict with other audio devices, like a USB audio interface or Bluetooth headphones that are taking precedence. Try disconnecting other audio peripherals temporarily to see if your monitor pops into the list. The last time I had a Mac audio issue, it was because my Bluetooth audio receiver was automatically connecting and hogging the output. Unpairing it for a few minutes let the monitor’s HDMI audio become selectable. It felt like the Mac was saying, “Oh, you wanted *this* device? Why didn’t you say so!”
The process of how to get audio to come through 2nd monitor on macOS is generally more intuitive, but the underlying principles of device detection and driver support remain the same. If it’s not appearing, start with checking the cable, then the monitor’s capabilities, and then look at your system’s audio output selection.
Troubleshooting Common Issues: The Nitty-Gritty
So, you’ve tried selecting the monitor, updating drivers, and your second screen is still resolutely silent. What else could it be? Let’s think outside the box for a second, or rather, outside the standard audio settings. Sometimes, the issue isn’t that the audio *can’t* go to the second monitor, but that another application is forcing it elsewhere. For example, if you’re using a VoIP application like Discord or Zoom, these often have their own audio output settings that can override your system defaults. Check the settings within any communication or conferencing software you have running.
Another, slightly more obscure, issue can be with audio enhancements. In Windows, these are often enabled by default and can sometimes cause weird conflicts. You can usually find these by going to Sound Settings > More sound settings > Playback tab > Right-click your monitor’s audio device > Properties > Enhancements tab. Try disabling all enhancements. I’ve seen this solve bizarre audio routing problems that no amount of driver updates could fix. It’s like a hidden layer of complexity that’s only supposed to make things better but sometimes just complicates the plumbing.
Lastly, consider the cable itself. A damaged or low-quality HDMI or DisplayPort cable might be capable of carrying video but struggle with the more robust data required for audio transmission. It sounds a bit like blaming the plumbing for a leaky faucet, but I’ve had cables that worked ‘mostly’ fine for video that would drop audio intermittently. Swapping it out for a certified, higher-quality cable (especially for DisplayPort, which can be more sensitive) is a surprisingly effective fix. A cable costs about $15, and if it solves the problem, you’ve saved yourself hours of frustration. Think of it as cheap insurance against tech headaches.
The Verdict: It’s Usually Simple, but You Gotta Know Where to Look
After wrestling with this more times than I care to admit, I’ve found that getting audio to come through a second monitor boils down to a few key checks. It’s rarely a hardware fault with the monitor itself, and more often than not, a software configuration issue. The most common culprits are the OS sound settings, graphics drivers, and occasionally, application-specific audio routing. (See Also: How To Monitor My Sleep With Apple Watch )
My personal experience has taught me that assuming things should “just work” is a fool’s errand in the tech world. You often have to be proactive and dig into the settings. For instance, when I was setting up my media PC connected to my TV, I spent a good hour figuring out how to get audio to output correctly. I finally found it was a combination of selecting the correct HDMI output in Windows and then also ensuring the audio format in the advanced settings of that device was compatible. It was that final, tiny tweak that made the difference, and it felt like solving a Rubik’s cube blindfolded.
| Component | Function | Potential Issues | My Verdict |
|---|---|---|---|
| Operating System Sound Settings | Manages audio output devices. | Incorrect device selected; drivers not recognizing device. | Must-check first. Usually the easiest fix. If the device isn’t listed, something else is wrong. |
| Graphics Card Drivers | Facilitates communication between GPU and display/audio hardware. | Outdated, corrupt, or incompatible drivers. | Essential. Update these regularly, especially after major OS or GPU changes. |
| Monitor’s Audio Capabilities | Determines if the monitor can receive audio signals (via HDMI/DP) or has built-in speakers. | Monitor only supports video; audio port not enabled. | Check the specs! Don’t assume. Many monitors are video-only. |
| HDMI/DisplayPort Cable | Carries video and audio signals. | Damaged, low quality, or incompatible cable. | Worth swapping if other steps fail. A cheap fix for subtle signal issues. |
| Application Audio Settings | Specific software might override system defaults. | Communication apps (Discord, Zoom) forcing audio elsewhere. | Easy to overlook. Always check apps that heavily use audio. |
What If My Monitor Doesn’t Have Speakers?
If your monitor physically lacks speakers, it won’t have an audio output device for your computer to send sound to directly. In this case, you’ll need to use external speakers or headphones connected to your computer’s audio jack or via USB/Bluetooth. You’d then select *that* device in your computer’s sound settings, not the monitor.
Can I Send Audio to Both Monitors at the Same Time?
Yes, you can often configure your system to send audio to multiple devices simultaneously. This usually involves using third-party software or advanced audio configuration within your operating system or audio drivers. It’s not always straightforward, and the results can vary depending on your hardware and software setup.
My Monitor Is Listed, but There’s Still No Sound. What Now?
If your monitor is showing up as an audio output device in your system settings, but you still get no sound, try these steps: 1. Check the volume levels on both your computer and the monitor itself. 2. Try disabling any audio enhancements in your sound settings. 3. Update your graphics card drivers. 4. Test the audio with a different application or media file. 5. If possible, test the monitor with a different audio source or cable to rule out the monitor or cable as the issue.
Verdict
Figuring out how to get audio to come through 2nd monitor isn’t rocket science, but it definitely requires a bit of patience and knowing where to poke around. Don’t get discouraged if it doesn’t work immediately; most of the time, it’s a simple setting overlooked.
Honestly, the biggest takeaway for me was realizing that the technology isn’t always as intuitive as we’d like it to be. Sometimes you just have to roll up your sleeves and hunt down that one obscure setting. For most people, it’s just a matter of selecting the right output device in Windows or macOS, or maybe a quick driver update.
If you’ve gone through all the standard steps and you’re still stuck, consider what you’re actually trying to achieve. Do you need audio *from* the monitor, or just audio playing near it? Because sometimes a simple external speaker setup is a far less stressful path than trying to force a feature your hardware doesn’t quite support.
