No sound when connecting via HDMI or DisplayPort video cable – Dell

Introduction

Ah, the woes of modern technology! You’ve just set up your fancy Dell display, and you’re ready to blast the latest episode of your favorite sitcom. But wait, what’s this? No audio? It’s like getting a front-row seat at a great gig only to discover the singer’s lost their voice. Classic, isn’t it? Buckle up, because we’re diving into a delightful disaster known as “What Happens When Your Computer Gets Lazy.”

Symptoms

Let’s state the obvious: audio playback does not work when a Dell display is connected to your computer using a DisplayPort or HDMI cable. So, if you’re sitting there looking like a kid on Christmas morning, only to find out your present is just more socks—well, that’s the vibe.

Cause

Now, here’s where it gets spicy. Windows, in its infinite wisdom, decides that when you use a fancy video cable, it’s smarter than it really is. It thinks, “Oh! I see an audio-enabled cable! There must be an audio device in use!” Problem is, the cable is as clueless as a cat trying to understand a dog’s bark. This usually happens when your laptop wakes up from its beauty sleep, like a teenager rolling out of bed at noon—completely disoriented.

Resolution

Don’t worry, mate! We can fix this mess quicker than you can say “digital disaster.” All you need to do is change the playback device configuration in the Control Panel. Just don’t forget, you can only set one device as the default playback device; it’s not a popularity contest!

To change the default audio playback device in Windows 10

1. Click on Start then on Settings (gear icon). Yes, it’s hidden in plain sight—classic.
2. Click on System.
3. In the left menu, click Sound. Yes, it’s supposed to be ‘sound’, not ‘son’, although I do like the latter for dramatic effect.
4. Under Choose your output device, select the audio device you want to use. It’s like picking your favorite child, but with less guilt.

To change the default audio playback device in Windows 8 or 8.1

1. Right-click Start then on Control Panel. Remember that? It was the cool kid before the Settings took over.
2. Click on Hardware and Sound.
3. Click on Sound.
4. In the tab Playback, select the audio device you actually want to use. The one you won’t be ashamed to admit to.
5. Click on Set Default then on OK. This confirms your decision. May the audio odds be ever in your favor!

Pro Tip

If the external audio device continues to cause problems, you can always disable it. It’s like giving that annoying ex a one-way ticket out of your life—poof! Gone!

Symptoms

Audio playback does not work when a Dell display is connected to the computer using a DisplayPort or HDMI cable.

Cause

When a video cable with audio support is used, such as a DisplayPort or HDMI cable, Windows may change the default audio playback device to the cable with audio support because it incorrectly detects another audio device is in use. The problem usually occurs when a laptop wakes up from sleep mode because the system detects the cable with audio support first.
