Another two feature Ultra USB Power, where the 5 V supply is derived from a 12 V rail that fluctuates less than a typical 5 V rail under heavy loads and shields it from noise from other devices such as RGB lighting for better audio quality on devices connected to those ports.
I have my doubts
(friendly for that's bullshit or marketing).
A voltage regulator is most likely also a switched regulator which introduces interference. The text implies there is some circuit which converts 12VDC to 5VDC.
If you have issues with your Voltages I may suggest replacing the power supply in the first place. I would get a better mainboard with better design if those effects happens. I also expect an usb audio interface or similar device to have a proper input circuit to reduce interference from the USB ports. If it's done via cables or other way is up to the designer of those usb devices.
I assume that all those audio nerds would have seen such issues long time before. Maybe also measured interference while testing usb audio interfaces or other usb devices.
The CPU header is limited to 1 A/12 W, and we're waiting on clarification from ASRock whether the remaining seven 4-pin fan headers are limited to 3 A/36 W in total or per port, as this isn't clear in the manual.
Most mainboard manuals are hardly ever updated. I expect a manual with clear and easy to read specs.
Many asrock mainbaords have a much better design with the wlan module accessable on the board like a m2 nvme module.
My ASUS mainboard uses a similar design. If you want to replace the wlan module you will have to remove the mainboard from the case. Than remove the screws from the mainboard backside. Than open the metall box to change the notebook sized wlan module.

I miss more USB-C ports on the backpanel. I miss overall several usb ports on the backpanel.
I miss the 10gbps Ethernet port on the backpanel. Or two 10gbps Ethernet ports on the backpanel. One 5gps Ethernet seems to be mainstream as of now.
The onboard Audio has only two instead of five connectors which were common on past AMD mainboards.
