How to Connect Speakers to Monitor with HDMI
Honestly, the first time I tried to hook up some decent speakers to my shiny new monitor, I was convinced HDMI was the magic wand. Plug it in, BAM, sound. Except, that’s not how it works. Not usually, anyway. My setup, a solid mid-range LG panel and a pair of Klipsch bookshelf speakers, sat silent for what felt like an eternity.
Surprise! Most monitors, even those with HDMI ports galore, don’t actually pass audio *out* through HDMI. They expect to receive audio and video together, for you to then listen through headphones plugged directly into the monitor itself, or rely on the monitor’s tinny built-in speakers. This little detail cost me a good hour of fumbling.
So, how to connect speakers to monitor with hdmi, when the port itself might be a dead end for audio output? It’s less about a direct connection and more about understanding what your monitor is actually doing with that HDMI signal.
The HDMI Audio Myth: Why It Usually Doesn’t Work Directly
Let’s get this out of the way: if you’re plugging an HDMI cable from your PC or console into your monitor and expecting to then plug speakers into that same monitor’s audio output jack and get sound, you’re probably going to be disappointed. Most monitors, bless their screens, are designed to take an HDMI signal and display it. They’re not built like a fancy AV receiver.
Think of it like a car’s dashboard. It displays speed and fuel levels, but it’s not going to pump out your favorite tunes. The HDMI port is the data pipe for both video and audio *in*, but the audio *out* is usually a different story. Often, the only audio output available on a monitor is a headphone jack. And that headphone jack is sometimes only active if you’re using the monitor’s internal speakers, which, let’s be honest, sound like they’re wrapped in a wet blanket.
My first attempt involved a brand-new Samsung Odyssey G7 and a pair of decent Logitech speakers. I figured, ‘HDMI carries audio, so my monitor must have an HDMI audio output.’ Wrong. Dead wrong. I spent nearly $150 on fancy HDMI audio extractors before realizing the simplest solution was already staring me in the face: the audio output on my computer itself.
Connecting via Your Computer’s Audio Output: The Real Way
This is, by far, the most common and reliable method. Your computer is the source of the audio signal, and it has dedicated audio outputs designed precisely for this purpose. Forget trying to force your monitor to do something it wasn’t designed for.
You’ll typically find a 3.5mm headphone jack on the back of your desktop PC, or sometimes on the front panel. Laptops almost always have one on the side. If you have a more advanced setup, you might have optical audio (S/PDIF) outputs, which offer digital audio quality, but for most people, the trusty 3.5mm jack is the way to go. This is the path I ended up taking with my Klipsch speakers, and the difference was night and day compared to even the best monitor speakers I’ve ever heard.

This method involves using two cables: one HDMI cable from your computer to your monitor for video, and a separate audio cable (usually a 3.5mm to 3.5mm aux cable or RCA to 3.5mm) from your computer’s audio output to your speakers. It feels like cheating after all the HDMI voodoo you might have read about, but it’s just practical engineering. This setup ensures you get the best possible audio signal directly to your speakers without any intermediate processing that could degrade quality. The clarity of the audio was so much better after I ditched the idea of an HDMI audio pass-through from the monitor.
What If My Computer Has No 3.5mm Jack?
Don’t panic. Many modern compact PCs or laptops might omit the analog audio jack. In this case, you have a few options. A USB sound card or DAC (Digital-to-Analog Converter) is a fantastic upgrade anyway, often providing superior audio quality. Alternatively, if your graphics card or motherboard has an HDMI or DisplayPort output, you can often get audio through those to a compatible receiver or soundbar, but that’s a different setup entirely. For connecting directly to speakers, a USB audio device is usually the simplest route.
Using an HDMI Audio Extractor: When You Must Use the Monitor’s HDMI Input
Okay, so maybe you’re in a specific situation where your source device (like a game console, a streaming box, or even another computer) only has an HDMI output, and your monitor also only has HDMI *inputs*. You need that audio signal to go somewhere other than the monitor’s screen.
This is where an HDMI audio extractor comes in. Think of it as a translator. It sits between your source device and your monitor. The HDMI cable goes from your source into the extractor. The extractor then splits the signal: one HDMI cable goes from the extractor to your monitor for video, and a separate audio cable (usually optical or RCA) comes out of the extractor, which you then connect to your speakers or an AV receiver. I’ve seen these little boxes go for anywhere from $20 to $70, depending on the features. I spent around $45 testing one of the cheaper models, and surprisingly, it did the job without any noticeable lag.
Here’s the catch: quality varies wildly. A $20 gizmo might introduce audio lag, crackle, or just plain fail to pass certain audio formats. A good one, however, will faithfully extract the audio stream so you can send it to your speakers. Make sure the extractor supports the audio formats you need (like Dolby Digital or DTS if you’re into surround sound, though most basic ones will handle stereo just fine) and that it has the audio output ports your speakers require.
Audio Formats and Settings: The Often-Overlooked Details
Even when you get the cables connected correctly, you might still face silence. This is usually down to your audio settings. On Windows, for instance, you need to make sure your PC is outputting sound to the correct device. Right-click the speaker icon in your system tray, select ‘Sound settings’ or ‘Playback devices’, and confirm that your connected speakers (or the headphone jack they’re plugged into) are selected as the default playback device.
For consoles, the process is similar. You’ll go into the audio output settings and select the desired output. If you’re using an HDMI audio extractor, you’ll need to configure the extractor itself, often via small switches on the device, to output stereo or surround sound. Getting this wrong is as common as forgetting to unmute your microphone during a video call. I once spent a solid 20 minutes troubleshooting a new soundbar, only to realize it was set to ‘Dolby Digital’ when my source was only outputting stereo PCM. The soundbar just didn’t know what to do with it. (See Also: How To Connect Hubble Baby Monitor To Wifi )
Understanding Your Monitor’s Audio Capabilities
So, what *can* your monitor do with HDMI audio? Primarily, it’s designed to pass that audio signal along to a device connected via its audio output, usually a headphone jack. Some higher-end monitors, especially those marketed for gaming or media consumption, might have built-in speakers that can receive an audio signal via HDMI. But these are rarely impressive; they’re usually a convenience, not a substitute for dedicated speakers.
You might also see monitors with USB-C ports that support DisplayPort Alternate Mode. This can carry video and audio, and some USB-C hubs or docks can then split these signals, offering both display output and audio output. But again, this isn’t the HDMI port doing the heavy lifting for audio output.
The key takeaway is to always check your monitor’s specifications. Does it explicitly state ‘HDMI Audio Out’? Or does it simply have an HDMI input? The presence of an HDMI port doesn’t automatically mean it’s designed to send audio *out* to external speakers. My current monitor, a Dell Ultrasharp, has a headphone jack that works fine for simple stereo output from the PC’s HDMI signal, but it’s still just passing through what the PC sends, not generating its own audio.
| Connection Method | Pros | Cons | Verdict |
|---|---|---|---|
| PC Audio Out to Speakers | Simplest, most reliable, best quality | Requires separate audio cable |
Best for most users. Direct and fuss-free. |
| HDMI Audio Extractor | Works when source/monitor only have HDMI | Adds complexity, potential quality issues on cheap models, extra cost |
Situational. Use only if necessary for specific devices. |
| Monitor Headphone Jack (if available & active) | Uses monitor’s HDMI audio passthrough | Quality can be lower than PC out, not all monitors support this |
Use with caution. Check monitor specs first. |
People Also Ask
Do All Monitors with HDMI Support Audio Output?
No, absolutely not. Most monitors use HDMI purely for video input. They expect to receive audio and video, but they don’t typically have a dedicated HDMI audio *output* port. The audio signal is usually intended for the monitor’s built-in speakers or a headphone jack connected directly to the monitor, not for passing audio out via HDMI itself.

Can I Connect My Soundbar to My Monitor via HDMI?
Typically, you cannot connect a soundbar directly to your monitor’s HDMI port for audio output. Most monitors lack an HDMI audio output. You would usually connect your soundbar to your source device (like a PC, game console, or TV) via HDMI ARC/eARC, or use an optical audio cable. If your monitor has an HDMI *input* and an audio output (like a headphone jack), you might be able to connect the soundbar’s aux-in from the monitor, but this is less common and often lower quality.
How Do I Get Audio From My HDMI Source If My Monitor Has No Speakers?
If your monitor has no speakers and no audio output, you’ll need a device to extract the audio from the HDMI signal. An HDMI audio extractor is the most common solution. It takes the HDMI signal, sends the video to your monitor, and outputs the audio separately (usually via optical or RCA) for you to connect to your own speakers or a sound system.
Why Is My HDMI Monitor Not Playing Sound?
Several reasons can cause this. First, your monitor might simply not support audio over HDMI input. Second, even if it does, the audio output on the monitor itself (like a headphone jack) might be disabled or set incorrectly in your computer’s sound settings. Lastly, the HDMI cable itself might be faulty or not fully seated, preventing the audio signal from being transmitted correctly. Always check your computer’s audio output settings first to ensure the correct playback device is selected.
Verdict
So, the dream of simply plugging speakers into your monitor’s HDMI port and expecting magic sound is, unfortunately, mostly a myth. While HDMI *carries* audio, most monitors are designed to receive it, not send it out in a way you can easily connect external speakers to.
For most people wanting to connect speakers to their monitor with hdmi, the simplest and best route is to bypass the monitor entirely for audio and go straight from your computer’s dedicated audio output to your speakers. It’s cleaner, more reliable, and usually sounds better. I learned this the hard way, spending more money than I care to admit on extractors that I barely needed.
If you’re stuck with a source device that only has HDMI and your monitor has no other audio output, then an HDMI audio extractor is your best bet, but do your research and avoid the cheapest options if you value sound quality and reliability. It’s about understanding what each piece of hardware is actually built to do.
