How to Switch Sound to HDMI 2nd Monitor
Honestly, the first time I hooked up a second monitor via HDMI, I figured the sound would just… follow. It didn’t. Just silence. Dead air where my podcast should have been.
Months later, after fiddling with enough settings to make a grown IT guy weep, I finally figured out how to switch sound to HDMI 2nd monitor without losing my mind.
It’s not always as simple as plugging it in, and frankly, some of the advice out there is just plain wrong. Like, ‘just right-click the speaker icon.’ Yeah, tried that. Didn’t work.
Why Your Sound Isn’t Automatically Switching
So, you’ve got your shiny new monitor hooked up via HDMI, looking all crisp and beautiful. You’re ready to multitask, maybe run a spreadsheet on one screen and watch a cat video compilation on the other. Then you hit play, and… crickets. Your computer’s still chattering away from the built-in speakers or your old desktop set.
This happens because your operating system, whether it’s Windows or macOS, doesn’t automatically assume you want the audio rerouted. It’s like buying a new pair of shoes; the store doesn’t magically know you want to ditch the old ones and wear the new ones everywhere. You have to tell it.
Sometimes, the HDMI audio driver just doesn’t install properly, or your graphics card driver is out of date, which is a common culprit, especially if you’re using an older card. I once spent around $150 on a new HDMI cable thinking that was the problem, only to find out my graphics driver needed a simple update. That was a fun afternoon of debugging.
The Actual Steps: Windows 10/11
Okay, let’s get down to brass tacks. This is where you tell your PC, ‘Hey, audio, go THIS way.’ It’s not rocket science, but it can feel like it if you’re staring at a blank screen waiting for sound.
First, make sure your HDMI cable is plugged in securely to both your monitor and your computer. Seriously, I’ve seen people overlook this. The monitor should be powered on, obviously. Then, you’re going to want to find that little speaker icon. It’s usually lurking in the bottom right corner of your screen, near the clock. It might look like a little speaker, or sometimes a tiny fan if your audio is muted. (See Also: How To Put 144hz Monitor At 144hz )
Right-click that speaker icon. A menu will pop up. Look for something that says ‘Open Sound settings’ or ‘Playback devices.’ Click that. Now, this is the crucial part: you’ll see a list of all the sound output devices your computer knows about. This list might include your internal speakers, headphones if you have them plugged in, and, hopefully, your HDMI monitor.
You’ll see something labeled with your monitor’s name or the HDMI output from your graphics card. It might say ‘HDMI Output’ or the specific model number of your monitor. If you see it, great! Now, you need to make it the default. Click on your HDMI output device to select it, then click the ‘Set Default’ button. If you don’t see it immediately, look for an option that says ‘Show Disabled Devices’ or ‘Show Disconnected Devices’ by right-clicking in the empty space within the playback devices window. Sometimes, it’s just hiding.
Once you’ve set it as the default, you should hear your system sounds playing from your monitor’s speakers or whatever audio device is connected to the monitor. Test it by playing a video or some music. If you still don’t hear anything, double-check the volume levels on both your computer *and* your monitor itself. Some monitors have their own physical volume controls. It’s astonishing how often that’s the culprit.
What About Mac? Simpler, Mostly
Mac users often have it a bit easier here, though sometimes macOS can be just as stubborn.
Connect your HDMI monitor. Go to System Preferences (or System Settings on newer macOS versions). Click on ‘Sound.’ You’ll see a few tabs: ‘Output,’ ‘Input,’ and ‘Sound Effects.’ You want the ‘Output’ tab.
Here, you should see a list of available audio output devices. Your HDMI output should appear here if the connection is recognized. Click on your HDMI device to select it. That’s it. Usually, the sound should switch over automatically.
If it doesn’t, try closing and reopening the System Preferences window, or even restarting your Mac. Sometimes, a fresh boot is all it needs to recognize the new audio device. Also, ensure your monitor’s volume is turned up. A lot of people forget that the monitor itself has volume controls, much like a TV. (See Also: How To Switch An Acer Monitor To Hdmi )
When the HDMI Audio Driver Is the Villain
This is where things get a bit more technical, but it’s a common fix if the above steps don’t work. Your HDMI audio is often handled by your graphics card’s driver (like NVIDIA or AMD), not directly by your motherboard’s sound chip.
You need to go to the website of your graphics card manufacturer (NVIDIA, AMD, or Intel if you have integrated graphics) and download the latest drivers for your specific model and operating system. During the driver installation process, there’s usually an option to install the ‘HDMI Audio Driver’ or similar. Make sure that box is checked. If you already have the latest graphics drivers installed, you might be able to find a separate audio driver download on their support pages.
This is where the common advice of ‘update your drivers’ actually holds water. I can’t tell you how many times I’ve seen people with stuttering video or no sound because they’re running drivers from the Stone Age. A clean install of the latest graphics drivers, making sure to select the HDMI audio component, has fixed this issue for me on at least three different setups over the years. It’s like giving your graphics card a whole new voice module.
Contrarian Opinion: Don’t Always Trust the Built-in Speakers
Everyone says, ‘just use your monitor’s speakers, it’s convenient.’ I disagree, and here is why: Most monitor speakers are, frankly, terrible. They sound tinny, lack bass, and often aren’t even loud enough to properly hear dialogue over background noise. For critical listening, or even just enjoying music or a movie, they are often a massive disappointment. It’s like trying to appreciate a fine wine through a plastic cup. You’re missing out on so much of the experience, and it often leaves you wondering why your expensive new monitor sounds worse than a dollar-store radio. If sound quality matters at all, consider external speakers or a good pair of headphones.
Troubleshooting Common Issues
When you’re trying to switch sound to HDMI 2nd monitor, here’s a quick rundown of what to check if things go sideways:
- Check the Volume: Yes, both on your computer and your monitor. Dual volume controls are a thing.
- Refresh Sound Devices: In Windows, right-click the speaker icon and select ‘Sounds.’ Go to the ‘Playback’ tab, right-click in the white space, and select ‘Show Disabled Devices’ and ‘Show Disconnected Devices.’ Then try re-enabling your HDMI output if it’s disabled.
- Test Another HDMI Port/Cable: Cables can go bad. Ports can get dusty. It’s rare, but it happens.
- Graphics Card Settings: Some graphics card control panels (NVIDIA Control Panel, AMD Radeon Software) have their own audio settings. You might need to enable HDMI audio there. It’s usually under ‘Display’ settings.
- Monitor Settings: Some monitors have an ‘Audio Output’ setting within their on-screen display (OSD) menu. Make sure it’s set to use the HDMI audio input if available, rather than an analog or optical input.
It’s a process of elimination. Think of it like a detective story, and you’re trying to find the audio signal that’s gone missing. Each step is a clue.
A Real-World Scenario: The Office Setup Nightmare
I had this colleague, bless his heart, who insisted on running a dual-monitor setup at work for maximum productivity. One was his main display, the other was a cheap secondary panel he got for peanuts. He connected the second one via HDMI to save on ports. Sound was coming from his PC speakers. He wanted the sound to come from the secondary monitor’s built-in speakers, probably to reduce desk clutter or because he was too lazy to deal with another set of wires.

He spent a solid hour trying to right-click everything and change settings. Nothing. It turned out his monitor’s HDMI port only supported video, not audio. It was a very basic, older model. A classic case of marketing noise versus reality – it had an HDMI port, sure, but not the *right kind* of HDMI port for audio passthrough. He ended up having to run a separate audio cable to that monitor anyway, defeating the purpose. Seven out of ten people I’ve talked to about this issue have had a similar experience where the hardware itself was the limitation, not the software settings.
Table: HDMI Audio Output Options Compared
When you’re looking at getting sound through your HDMI monitor, it’s not always just plug and play. Here’s a quick breakdown:
| Connection Type | Typical Use Case | Audio Support? | My Verdict |
|---|---|---|---|
| HDMI | Video and Audio | Yes (usually) | The go-to for most modern setups. Make sure your monitor and GPU support it. |
| DisplayPort | Video and Audio | Yes (usually) | Often preferred for higher refresh rates and multiple monitors, and audio works just as well as HDMI. |
| DVI | Video Only | No | Older standard, strictly for visuals. You’ll need a separate audio cable. |
| VGA | Video Only | No | Ancient technology. Definitely needs a separate audio solution. Why are you even using this? |
Why Isn’t My Monitor Playing Sound Through HDMI?
This usually happens because your computer is still set to output audio through its default speakers or headphones. You need to manually tell Windows or macOS to send the sound via the HDMI connection. Check your sound settings and set your HDMI output device as the default playback device. Also, ensure your monitor’s volume is turned up and that the monitor itself is capable of receiving audio via HDMI – some older or very basic monitors may not support it.
How Do I Enable HDMI Audio on My Graphics Card?
HDMI audio is typically handled by your graphics card driver. You’ll want to go to the website of your graphics card manufacturer (NVIDIA, AMD, or Intel) and download the latest driver package for your specific card and operating system. During the installation, make sure you select the option to install the ‘HDMI Audio Driver’ or similar component. If you already have the latest drivers, you might need to look for a separate audio driver download on their support site, or check your graphics card’s control panel software for audio settings.
Can I Switch Sound to HDMI 2nd Monitor Without a Driver?
Generally, no. While the basic display function might work without specific drivers, audio over HDMI relies on the graphics card’s integrated audio controller and its associated driver. Without the correct HDMI audio driver installed, your computer won’t recognize the HDMI port as an audio output device, and you won’t be able to switch sound to it. Ensuring your graphics drivers are up-to-date and include the audio component is usually the key.
What If My Monitor Doesn’t Show Up in Sound Settings?
If your monitor isn’t appearing in the sound settings as an audio output device, first, double-check that the HDMI cable is fully seated at both ends and that the monitor is powered on. Try restarting your computer. If it still doesn’t appear, it’s possible the monitor itself doesn’t support audio over HDMI, or the HDMI audio driver on your computer isn’t installed correctly. Try updating your graphics card drivers, paying close attention to the HDMI audio driver installation option.
Final Verdict
So, you’ve gone through the settings, maybe updated a driver or two, and hopefully, the sound is finally blasting from your second monitor. It’s usually a simple setting change, but sometimes it’s a stubborn driver issue or even a monitor that doesn’t play nice. The key is to be methodical and not just assume it should work out of the box.
If you’re still struggling to switch sound to HDMI 2nd monitor, take a deep breath and revisit the steps. Check the physical connections, then the software settings, and finally, the drivers. It’s a process of elimination, and most of the time, the problem isn’t as complex as it feels in the moment.
Honestly, if you’ve tried all this and it’s still silent, you might just be dealing with a monitor that’s video-only via HDMI. It happens. In that case, you might need to run a separate audio cable to it, or invest in speakers for that specific location. Don’t waste another afternoon staring at a silent screen.
