The Intel High Definition Audio driver that came with this laptop was not compatible with Windows 10 v2004 Feature Update recently released via Windows Update. However, the Realtek HD Audio driver still works. The driver downloads page specifically for this laptop is only for version 1903 or 1909
Please alert your driver development team or department of this issue.
Feature update windows 10 2004 messes up the Intel HDMI audio which is installed with the Intel Iris Graphics Plus driver on the HP Pavilion 15 cs 3075 wm. After the 2004 update is applied it shows up as Intel High Definition audio with a Red alert symbol next to it in the device manager. An attempt to install v1909 of the driver fails.
