Check windows advanced display settings often after major updates it will reset the Framerate to 29.997HZ and sometimes it will also reset your power management plan to standard or performance rather than high performance.
These 2 windows features can effect the functionality of your display/audio software.
I run an MSI MOBO in my build.
You may want to open a support ticket with MSI/support.com and get a phone conversation if you can. Trust me having worked IT field jobs it is way easier because you usually get to speak to an actual tech that knows what they are doing rather than a desk jockey just reading instructions off a screen like a pre recorded message.
