Below goes borderline offtopic as i rant about a feature on FA's board, but ugh why are people doing dumb stuff like this to confuse everyone about USB-C
My B550 has 3 of them, but one is USB 2.0 speed I think
I have only had B550 boards so I cannot comment
You can see some weird shite with USB 3.x, but that comment had me sure you were wrong - but nope, you get a type-C "Audio" port for whatever reason.
The official webpage for your board makes it sound like the port is designed for USB 2.0 DAC's, but nope - it's an output for a special cable of theirs from the onboard solution?!?
They don't even picture the included cable adaptor or mention it anywhere in the specs or manual that i've seen so far.
It literally seems to just divert the onboard analogue audio over the included cable, giving you... a second set of analog jacks right next to the existing ones?
"USB Type-C Audio is really analog signals over USB. And that is bad because you are passing audio right next to power lines of USB, which can cause interferes which can be audible"
Reddit and the asus forums are full of confusion since they spaz out and behave weird, or refuse to activate at all - because it seems like a one or the other situation, it;s like they divert the front panel audio (or rear ports or SPDIF or something) to those jacks and send plain old analogue sound over it - any other devices connected, it's just USB 2.0
It's broken for most users and requires specific BIOS versions and settings, AND software combinations to work
Apparently its stereo analog only, no mic support, and often really crackly
Why grab a weird tech standard that doesn't make sense at all, and slap it on a motherboard? Oh right, asus sell a heap of USB-C audio accesories - they want you to buy those, even tho they don't need this port
seems entirely useless when it already has 3.5mm jacks RIGHT NEXT TO IT
On the more generic USB 3.x and AMD chipset confusion topic:
USB-C at a design level you could wire something up as two single 5Gb ports, or merge them together to make one 10Gb type-C (since they're literally double sided, it's 5Gb each side)
You could then get USB-A ports that are 10Gb, that if they used that trick they'd become the 20Gb ports - but those are extreeeeemely rare, the fabled and lovingly named USB 3.2 gen2x2
If you used the single-sided stuff with USB 2.0, you get a simple USB 2.0 connection with type C at the end that likely only works one way around, but if everything follows the specs properly works facing both ways (Some of these weird combos only function one way around)
Those 3.2 gen 2 ports are all 10Gb, so you have 3 USB A and one USB-C at the rear that are all 10Gb, regardless of if you use A-B or A-C cables
You get 4x10Gb and 4x 480Mb, when my older x570 gets 4x 5Gb and 4x10Gb
Then your front ports are two 5Gb type A and one 10Gb type C (same as x570, this setup seems common - they internally converted two 5Gb ports into a 10Gb 2x2 type C))
Yeah I meant the adapter for the USB header on the motherboard, since I only have one (broken, lol, those things are made of cardboard) usb 3 header.
Mostly to make the usb-c port useful. Aware it'll lock me on usb 2 speeds.
Ah gotcha, to let you use 2.0 case ports off the 3.0 headers on the motherboard
Depending on your case and setup, those are really handy - i've even had to use those to connect RGB and fan controllers to a build once, since the board had two 3.0 headers
