Quote:Nothing is certain in life but death, taxes, and Windows 10 update bugs. While we were enjoying the holidays, Microsoft acknowledged it broke everything from Windows Media Player to the sound output on some PCs.

More Broken Intel Driver Updates

At exactly 5 PM eastern time on November 21—the day before Thanksgiving— Microsoft updated the Windows 10 Update History page to note a new problem with the October 2018 Update. On some systems with Intel graphics, audio playback from a monitor or television connected via HDMI, USB-C, or DisplayPort is broken.

Microsoft says this is because Intel released the wrong versions of its display drivers to PC manufacturers. Those PC manufacturers accidentally turned on unsupported features in Windows. Microsoft then released those driver updates and didn’t catch the problem before now. In other words, Microsoft, Intel, and PC manufacturers all messed up.

Windows 10 won’t install the October 2018 Update on systems with this hardware, as an “update block” is now in place. Microsoft is working with Intel to “expire” these drivers. If the update has installed on your system and broken your sound, here’s how to fix it.

Note that this is different from the bad driver update that broke the Intel sound on some PCs back in October. Thanks to Woody Leonhard for noticing this.
