How to fix Realtek audio issues after Windows 11 24H2 update?

Since the release of the Windows 11 24H2 update, a lot of users with Realtek audio drivers faced no sound, audio failure, and even Realtek software-related errors. Most of these were related to the incompatibility of the drivers and the conflicts brought forth by this update, whereby users have not been able to make any use of their audio thus far.

Users affected by this issue commonly describe either no sound or intermittent audio. In some cases, the Realtek audio driver may not be recognized at all or show up as a blank or non-functional device in Device Manager. Others report Realtek audio software errors or the complete absence of sound.

Potential causes may include:

• Incompatible drivers. The Realtek drivers may not be fully compatible with Windows 11 24H2, leading to functionality issues.
• Driver conflicts. Conflicts between new system drivers and the existing Realtek driver can cause malfunction.
• Outdated or corrupted drivers. Older or corrupted drivers may fail after the update, resulting in a loss of sound.
• Windows update bugs. New bugs introduced by the Windows 11 24H2 update can disrupt the connection between the operating system and audio drivers.
• Hardware issues. While less common, hardware problems could coincide with the timing of the update and cause issues with Realtek audio devices.

Many users have had success by rolling back to a previous driver version or downloading updated drivers from Realtek's website. Others have fixed the problem by reinstalling or updating their drivers through Device Manager. Adjusting sound settings, such as disabling sound enhancements, has also resolved the issue for some users.
