I have you beat. Intel didn't bother on their driver error message. -> Do not fall into the trap laid by others telling you to ALWAYS update drivers. We update when there's an issue. If it works, there is no issue most of the time.
My error on Windows 10:
And no. I never bothered to fix it because that error happened only twice in a year.
So I built a custom desktop, which I installed windows 7 on when I built it, but upgraded to windows 10. My PC is a few years old now, and I checked my realtek audio drivers, and they are version 18.104.22.16830, last updated in 2016. I checked on realtek's website and those drivers are for windows 7. I am using windows 10, always download new windows updates and install them, and even have a program to scan new software updates for all my hardware. I went into device manager and clicked update, search online, but it says it's up to date. How come my computer says that a year-old windows 7 audio driver is up to date, when this is may 2017 and I've updated to windows 10 since then? Should I manually download a newer HD audio driver from Realtek for windows 10, or leave it alone?
