There is a problem with the latest version of Windows 11 22H2 and 7.1 Surround Sound. Installation is fine and working great, however the moment OS get rebooted, Audio Device Graph Isolation service start to behave strange with CPU usage 5-10% on 12 core xeon which is a lot load for nothing. Tried to reinstall it with no luck after OS reboot is the same. I currently uninstall it to prevent unnecessary CPU usage, for reference I’m using Realtek ALC221, driver version 6.0.9013.1 I hope DEV team to look into this matter.
