Microsoft has shipped an update for Windows 10 PCs that should fix an issue that caused audio to stop working on PCs after installing Intel Smart Sound Technology driver version 09.21.00.3755.

The issue was the result of the updated Intel driver being sent to some PCs by mistake. After reports began surfacing, Microsoft posted a workaround (opens in new tab) that involved manually uninstalling the driver. The update released today as KB4468550 (opens in new tab) (via OnMSFT) will automatically remedy the issue for those affected who haven't already manually uninstalled the driver themselves.

From Microsoft:

This update addresses an issue where after installing the Intel Smart Sound Technology driver (version 09.21.00.3755) via Windows Update or manually, computer audio may stop working.

Once installed, audio should begin working again, though you may have to restart your PC once the update is applied.

If your PC is affected by the audio issue, you should be able to grab the update via Windows Update now. Alternatively, you can manually download and install the update through the Microsoft Update Catalog (opens in new tab).

  • Never thought the audio issues my wife had on her spectre x360 are her to an update, good to know Microsoft fixed it.
  • Will all Windows 10 PC now support Wake from Sleep using "Hey Cortana".
    I asked Best Buy and they said it is a modern standby feature in Windows 10.
    Is that accurate ?
  • As of now only windows 10 on arm can do that
