Current motherboards with onboard Stereo Mix (What you Hear)??

[Basil]

I want to update my Windows 7 PC but need a motherboard with Stereo Mix, sometimes called "What You Hear" available from the on board sound device. Can anyone suggest some current motherboards that DEFINITELY have this option and KNOW it works please? I will probably be using an Intel processor, nothing bang up to date state of the art, but better than my current i5 4670K processor. I do not game nor do I do anything graphics intensive. If it were to have a true serial port that would be excellent, but it WOULD need to accept a hardware level serial port card. Thanks.

New MB (coffee Lake) aren't compatible with Win 7.
You have a excellent computer (GA-Z97X+ i5-4670K +16G + Win 7 pro).
I wouldn't change, unless you install Win 10.

If you want a Sophisticated sound card, buy a PCIe.

$9 here. I'm not aware of a recent vintage motherboard with a native serial port
