Tried the Win10 driver? I'm not on 11 yet so I don't know if there are significant changes that would prevent you from using 10 drivers but that has worked in the past.
Going on 8 months of ownership for this sound card. Still can't use my headphones in Win11. Windows 11... going on 5 months of public release. Over a year of being out for development purposes. I hope Asus realizes they are the laughing stock right now for sound card support.
WHAT A LET DOWN.
AE-7 Sound card in my cart ready to purchase if this May 2022 driver release date slips again. Will never recommend another Asus sound card in my life!
May 2nd, still no Audio Drivers. I keep updating my amazon review for the strix dlx card with dates. As long as you keep not updating the driver for an operating system that has been out for over a year.... I'll keep updating my review to help educate people on not buying their sound cards.
