Hi Alex! My name is David. I am a user of Microsoft products like you, and it is a pleasure to greet you.
Regarding your question, it is likely that the download link you tried to use has indeed expired. While it is good to use the official Realtek page for downloading the audio driver, I am sharing some alternatives that might also be helpful:
- As you are currently doing, use the official Realtek page to download the Windows audio driver: https://www.realtek.com/Download/List?cate_id=593
- You can also use the Windows Update Catalog to search for and download audio drivers that have been shared with Microsoft: https://www.catalog.update.microsoft.com/Search... This search is focused on the 24H2 version of Windows 11, but you can use the same search criteria with the version you currently have installed.
- Finally, I suggest downloading the driver directly from the official website of your PC manufacturer or motherboard manufacturer to ensure full compatibility.
Note: This is a non-Microsoft website. The page appears to be providing accurate, safe information. Watch out for ads on the site that may advertise products frequently classified as a PUP (Potentially Unwanted Products). Thoroughly research any product advertised on the site before you decide to download and install it.
Let me know if the shared information has been helpful. Regards.
