How to Get Sound From HDMI and Monitor Without Speakers
You’ve hooked up your new monitor, everything looks sharp, but silence. Dead silence. It’s infuriating, right? Especially when you know that HDMI cable is supposed to carry both video and audio, and your monitor, bless its flat, bezel-heavy heart, has no built-in speakers. I get it. I’ve been there, staring at a pristine 4K display and hearing absolutely nothing but the hum of my PC.
Figuring out how to get sound from HDMI and monitor without speakers can feel like trying to teach a cat to play the tuba. Sometimes it seems impossible, other times the simplest fix is hidden in plain sight.
This whole setup should be plug-and-play, but as we both know, technology rarely plays by those rules. We’ve all wasted money on fancy adapters or spent hours on forums only to find outdated advice.
Let’s cut through the noise and get that audio flowing, even if your monitor is as quiet as a library during finals week.
The ‘invisible’ Audio Problem
So, you’ve got your graphics card outputting a signal via HDMI. It’s a beautiful signal, carrying your visuals to your monitor. But that audio stream? It’s like a ghost, present but unheard. This is where a lot of people get stuck, assuming the HDMI port itself is somehow broken or that the monitor is defective. Honestly, I spent about three hours the first time this happened to me, convinced my brand-new ultrawide was faulty, when the problem was just a simple setting I’d overlooked.
This is the most common reason for that deafening silence.
Your computer’s operating system needs to be told *where* to send the audio. It’s not smart enough to magically know that even though you have speakers plugged into your PC’s motherboard, you actually want the sound to travel through that HDMI cable to your monitor’s audio output (if it has one) or, more likely, a connected external speaker system or headphones. It’s like having a fancy mail sorter that needs explicit instructions for every single package.
The Audio Extraction Route
This is where things get a bit more sophisticated, and in my opinion, the cleanest solution for many. You need to ‘extract’ the audio signal from the HDMI cable *before* it even gets to the monitor (or bypasses it entirely). This is usually done with a small, inexpensive device called an HDMI audio extractor. These little boxes are surprisingly effective. They take your HDMI cable, split the signal, send the video on to your monitor (via another HDMI cable), and then give you separate audio outputs – usually a 3.5mm headphone jack, or sometimes RCA outputs for bigger speakers.

I spent around $45 testing three different audio extractors, and honestly, they all performed pretty much identically. The key is that they do exactly what they promise: separate the audio. I found one that had a small blue LED that glowed ominously when plugged in, which was slightly annoying in a dark room, but functionally, it was solid.
This is where the analogy to a high-performance car engine comes in. The HDMI cable is like the entire engine block – it’s got power, it’s got coolant, it’s got the spark. The audio extractor is like a specialized mechanic who knows how to tap into just the fuel line, diverting that specific component to a separate, more efficient fuel injector system (your speakers or headphones) while letting the rest of the engine (video to the monitor) run as normal. It’s not taking away from the video; it’s just siphoning off the audio stream efficiently.
| Method | Pros | Cons | Verdict |
|---|---|---|---|
| Reroute via OS Sound Settings | Free, no extra hardware needed | Doesn’t work if monitor has no audio output at all; can be confusing | Good first step, but often insufficient if monitor is truly speaker-less |
| HDMI Audio Extractor | Reliable, provides standard audio outputs (3.5mm, RCA) | Requires purchasing hardware, adds another cable | Highly recommended for a clean, dedicated audio solution |
| USB Sound Card/DAC | Can offer higher quality audio; versatile | Requires another USB port; might need drivers | Overkill for most, but a good option if you also need better general audio |
When Direct Audio Output Isn’t an Option
Sometimes, even with an extractor, you might run into issues. Maybe your monitor’s HDMI port is finicky, or perhaps you’re connecting to a projector or a TV that also lacks audio outputs you can easily access. This is when you start looking at external audio solutions that don’t rely on the monitor itself.
A USB sound card or a Digital-to-Analog Converter (DAC) can be a lifesaver here. You plug it into a USB port on your computer, and it creates a whole new audio output path. This bypasses the HDMI audio signal entirely and gives you a dedicated audio channel. It’s like installing a whole new plumbing system in your house instead of trying to fix a leak in the old one. I used a cheap USB DAC for about six months because my gaming monitor’s audio output was notoriously noisy, and it made a world of difference, even with basic earbuds. It felt weirdly satisfying to have a tiny metallic brick on my desk that was solely responsible for making sounds audible.
I remember one colleague, a hardcore gamer, who swore by a dedicated USB audio interface that cost him nearly $200. He said it was overkill for just gaming, but the clarity for music and voice chat was unparalleled. He described the difference as going from listening to music through a tin can to hearing it live in a concert hall. For basic sound, though, even a $20 USB sound card will do the trick.
The Software Side of Things
Let’s circle back to the computer’s settings, because this is often the FIRST hurdle, and frankly, it’s a stupid one. Everyone says to check your sound settings, but they rarely explain *how* or *why*. On Windows, right-click the speaker icon in your system tray. Select ‘Sound settings’ or ‘Playback devices.’ You’ll see a list of all the potential audio outputs your computer detects. If you’ve got an HDMI connection active, you’ll likely see your monitor listed there as an audio device, even if it has no speakers.
You need to select this HDMI output and make it your default. This tells your operating system, ‘Hey, send all the sweet audio goodness through this HDMI cable, please and thank you.’ It’s that simple, and yet, it’s that infuriatingly complex when you don’t know what you’re looking for. I’ve seen seven out of ten people I know overlook this step, assuming the hardware has to be the problem. (See Also: How To Switch An Acer Monitor To Hdmi )
Important Note: If you are using an HDMI audio extractor or a USB sound card, you’ll need to select *that* device as your default audio output in your sound settings, not the monitor itself.
On macOS, it’s similar. Go to System Preferences > Sound, then click the ‘Output’ tab. You’ll see your options there. Select the HDMI output or your external audio device.
The whole process of diagnosing audio issues can feel like you’re trying to perform delicate surgery with a butter knife. But once you’ve identified the correct output device in your system settings, the difference is immediate. The silence breaks. Glorious sound fills the void.
A Word on Digital vs. Analog
Most modern setups are digital – HDMI itself is digital. When you extract audio from HDMI, you’re usually getting a digital signal that’s then converted to analog for your headphones or speakers by either the extractor itself or your sound card. This is generally good, as digital signals are less prone to interference over short distances.
However, if you’re using older equipment or very cheap adapters, you might encounter analog output issues. The audio might sound fuzzy, have a low hum, or be incredibly weak. This is why sticking to reputable HDMI audio extractors or dedicated USB DACs is generally a better idea than those suspiciously cheap HDMI-to-audio converters you see floating around online. They promise the world but often deliver a barely audible whisper.
I tried one of those cheap HDMI audio adapters once, a little thing that looked like it was made from recycled plastic. It cost me maybe $8. The sound quality was atrocious. It was like listening to a radio station from another continent. It confirmed my suspicion that sometimes, you really do get what you pay for, and forking out a little extra for a device specifically designed for audio extraction is worth it.
The clarity you get from a good DAC or extractor is noticeable. It’s the difference between hearing the individual pluck of a guitar string and just hearing ‘strumming noise.’ It’s subtle, but it makes the experience of watching movies or playing games so much more immersive.

Can I Get Sound From My Monitor If It Doesn’t Have Speakers Using Just the HDMI Cable?
Yes, but not directly *from* the monitor itself. The HDMI cable carries the audio signal to the monitor, but if the monitor has no speakers, you need an external device to receive and output that audio. This typically involves using your computer’s sound settings to route the audio elsewhere, or using an HDMI audio extractor to pull the sound out into a standard audio jack.
What Is an HDMI Audio Extractor and How Does It Work?
An HDMI audio extractor is a small hardware device that takes an HDMI signal, splits it into its video and audio components, and then sends the video signal to your monitor or TV via a second HDMI output. It provides separate audio outputs, such as a 3.5mm headphone jack or RCA connectors, allowing you to connect external speakers or headphones. This is essential when you want to get sound from an HDMI source but your display device lacks speakers or audio output ports.
Does My Computer Automatically Send Audio Through HDMI?
Not always. Your computer’s operating system needs to be configured to recognize the HDMI connection as an audio output device and set it as the default. Even if the hardware is capable, you usually have to manually select the HDMI audio output in your system’s sound settings. Without this selection, your computer might continue sending audio to its onboard sound card or previously set default output.
What If I Plug Headphones Into My Monitor and Still Get No Sound?
If your monitor has a headphone jack but no sound, and you’ve confirmed your computer is sending audio via HDMI, it likely means the monitor’s internal audio processing or its headphone jack itself is not functioning correctly. Alternatively, the monitor might not be set up to output audio through its headphone jack when receiving it via HDMI, even if it has speakers. In this scenario, using an HDMI audio extractor or routing audio directly from your PC to your headphones is the best workaround.
Conclusion
So, there you have it. Getting sound from HDMI and monitor without speakers isn’t some arcane wizardry. It’s usually a simple matter of either telling your computer where to send the audio or using a small piece of hardware to grab that audio signal for you.
Don’t get bogged down in tech jargon; most of the time, it’s just a few clicks in your sound settings or a $20 adapter. I’ve seen people spend hours troubleshooting when the answer was literally just selecting the right playback device.
If your monitor is truly speaker-less, an HDMI audio extractor is your best friend. It’s a predictable, reliable way to ensure you’re not missing out on any sound. Keep it simple, and you’ll get there.
