Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
i dont know about your case but i know the motherboard can do it, you may have to disable front panel plugin detection if the case inputs dont support it like my microfly doesnt
What? You want input/input on both sides? Or output/output?
You can use both sides at once (say, mic in from the front, sound out from the back), but I'm not sure you can use two mic devices. Two sound out devices maybe.
