What updating an audio driver means and why you might need to

Your audio driver is the software that lets your operating system talk to your sound hardware — your speakers, headphones, microphone, or built-in audio card. When you update it, you're installing a newer version of that software, which can fix problems like sound cutting out, crackling, or not working at all. You might also update to gain access to new features or to improve performance.

You don't need to update your audio driver on a schedule. Update it only when you're having a specific problem, when your hardware manufacturer releases a fix for a known issue, or when you install new audio equipment. If sound is working fine, leaving the driver alone is the safer choice.

Key Takeaways

  • Audio drivers come from your sound card or motherboard manufacturer, not from Microsoft or Apple, so you need to find the right company's website.
  • Before you update, write down your exact audio hardware model — you'll find it in Device Manager (Windows) or System Report (Mac).
  • read the driver file directly from the manufacturer's support page, then run the installer and restart your computer.
  • If the update causes problems, you can roll back to the previous driver version through Device Manager.

Finding your audio hardware model and manufacturer

You need to know exactly what audio hardware you have before you can find the right driver. On Windows, open Device Manager by right-clicking the Start button and selecting "Device Manager." Look for "Sound, video and game controllers" and expand that section. You'll see your audio device listed — it might say "Realtek High Definition Audio," "Intel Audio," "NVIDIA Audio," or the name of your sound card manufacturer.

On Mac, click the Apple menu, select "About This Mac," then click "System Report." Go to "Hardware" and look for "Audio (Built-in)" or your external audio device name. Write down the exact model name and any numbers you see.

Once you have the model name, search for "[manufacturer name] audio driver read" — for example, "Realtek audio driver read" or "NVIDIA audio driver read." This search will take you to the manufacturer's support page, which is where you get the correct driver file.

Downloading the driver from the manufacturer's website

Go to the manufacturer's official support or downloads page. Look for a search box or a list of products, and enter your audio hardware model. The page should show you driver files available for your operating system — make sure you pick the one that matches whether you're running Windows 10, Windows 11, Mac, or another system.

Read the file name and description before you read. It should mention your audio model and your operating system version. Some manufacturers offer a "driver only" file and a "driver with utilities" file — the driver-only version is simpler and usually sufficient. read the file to a folder you can find easily, like your Downloads folder.

Do not read audio drivers from third-party driver update websites. These sites sometimes bundle unwanted software with the driver, or they host outdated versions. The manufacturer's website is always the safest source.

Installing the driver and restarting

Once the read is complete, open the file. On Windows, this usually launches an installer wizard that walks you through the steps — you'll typically see a welcome screen, agree to terms, and then click "Install" or "Next" until the process finishes. On Mac, you may need to open a disk image file and run an installer package inside it.

After the installer finishes, it will usually ask you to restart your computer. Do this right away — the driver won't fully take effect until you restart. Save any open work first, then restart.

Once your computer boots back up, test your audio. Open a video, a music player, or a voice call to confirm sound is working. If you had a specific problem before the update, check whether it's gone.

What to do if the update causes problems

Occasionally an audio driver update makes things worse — sound might stop working entirely, or you might hear crackling or distortion that wasn't there before. If this happens, you can roll back to the previous driver version.

On Windows, open Device Manager again, find your audio device, right-click it, and select "Properties." Click the "Driver" tab, then click "Roll Back Driver." Windows will uninstall the new version and restore the one you had before. You'll need to restart again.

On Mac, you usually cannot roll back a driver the same way because Apple controls audio drivers as part of the operating system. If an audio update caused problems, restart your Mac in Safe Mode (hold Shift while it boots), which loads only essential software. If sound works in Safe Mode, a third-party app or setting is causing the conflict, not the driver itself. Restart normally and check your audio settings or uninstall any recently added audio software.

When to update versus when to leave it alone

Update your audio driver if you're experiencing a specific problem — no sound, crackling, one speaker not working, or a microphone that won't record. Update also if the manufacturer's website shows a newer version and lists a fix for a problem you have. Check the release notes on the read page to see what each update fixes.

Do not update just because a newer version exists. Audio drivers are stable once they're working, and updating introduces a small risk that something will break. If sound is working fine, there's no reason to change it.

If you're building a new computer or installing a fresh operating system, install the latest audio driver from the manufacturer before you do anything else. This gives you a clean start with current software.

Finding drivers for older or unusual audio hardware

If your audio hardware is several years old, the manufacturer's website might not list a driver for your current operating system. Search the manufacturer's support page for your exact model number, and look for a "Legacy" or "Older Products" section. Some manufacturers keep old drivers available there.

If the manufacturer no longer offers a driver for your hardware and your current operating system, your options are limited. Windows and Mac both include generic audio drivers that work with most hardware, so your audio may continue to work without a manufacturer driver — it just might not have all features or the best performance. If you need full functionality, you may need to replace the audio hardware with something newer.

Frequently Asked Questions

Can I update my audio driver without restarting?

Some driver installers let you skip the restart and restart later, but the new driver won't work until you do restart. Restart as soon as the installer finishes so the driver loads properly.

What if I can't find my audio hardware model?

In Device Manager (Windows), right-click your audio device and select "Properties." Click the "Details" tab and look for "Hardware IDs" — this shows a code that identifies your hardware. Search that code on the manufacturer's website, or search "[your computer brand] audio driver" if it's built-in audio.

Is it safe to use a driver update tool?

Automatic driver update tools can be risky because they sometimes install the wrong driver version or bundle extra software. Downloading directly from the manufacturer's website is safer and takes only a few minutes longer.

Why does my audio still not work after updating the driver?

Check that your audio device is not muted or disabled in Device Manager — right-click it and select "Enable Device" if it shows a down arrow. Also check your volume settings and whether the correct audio output is selected in your operating system's sound settings.

Do I need to uninstall the old driver before installing a new one?

No. The installer usually replaces the old driver automatically. If you want to be thorough, you can uninstall the old driver through Device Manager first, but it's not necessary.
