Home / Driver Updater / Realtek High Definition Audio
A red cross on the speaker icon, “No audio output device is installed”, or sound that vanished after a Windows update - audio driver problems look scary but usually come down to a missing or mismatched driver. A free scan shows what your PC is actually using.
Your PC is currently running: Windows
The volume icon shows an error and no sound plays anywhere.
Windows reports no output device even though the speakers or headphones are connected.
Audio worked before the update; afterwards the Realtek audio is silent or gone.
The Realtek High Definition Audio entry disappeared or shows a yellow warning mark.
A free scan can identify the installed hardware and show available driver information.
These are the standard Windows checks - they take a few minutes and sometimes do the trick:
The weak spot of the manual route: at the "Update driver" step Windows searches only its own catalog, which is often missing or outdated for the exact model - it can report that the best driver is already installed even when a newer one exists. The free scan checks your devices against a database of 1,000,000+ drivers, so one pass shows whether better versions are available.
The application identifies the hardware installed on your PC and checks the current driver information.
See detected devices, installed driver versions and available updates. Nothing changes during the scan.
Review the results and decide which available updates you want to apply.
A license is required only if you choose to apply the available updates.
| Searching manually | Automatic detection |
|---|---|
| Find the exact device model | Installed hardware is identified |

The scan identifies the exact model Windows reports for your device and shows the driver updates available for it - you see the version and date before applying anything.
The scan checks the audio devices Windows can see, including the Realtek High Definition Audio chip they connect through - output selection stays yours.
No - the audio device is part of the PC, so it is visible to Windows already. Just run the scan.
No. Nothing changes during the scan. Driver updates are applied only after you review the results and choose what to update.
Yes. Each detected item can be reviewed, applied or skipped individually. Backup and restore options are available before updates are applied, so a previous driver version can be restored if necessary.
The button downloads Outbyte Driver Updater, a Windows desktop application. The website itself does not scan your computer in the browser - the check runs in the application after you install and start it.
The scan and results are free. A license is required only if you choose to download and apply the available updates. Current pricing and license terms are shown before purchase.
Supports Windows 11 and 10 · Uninstall anytime via Settings → Apps · If no updates are found, the scan still shows the current driver state of your devices.
