Try a complete power down, unplugged from all
sources, for at least a minute (to let the mother board
COMPLETELY lose power, except the RTC/EPROM battery), then
reboot. Some hardware (USB in particular) tends to occasionally
get a stuck 'bit' (or something) and losing ALL power (battery
too if laptop) sometimes fixes things.
If not, then order as you need.

I had an apparent failure of the audio
input section of the motherboard in my home brew Windows 10
based desktop computer just a couple of days before the recent
Field Day. No indication of FT8 audio on the audio level
indicator and nothing decoding. It had been working two days
earlier. Plugging a pair of headphones into the Line Output
jack on my K3 showed I had plenty of audio going to the
computer. No amount of messing around with computer
programming would make it play. I’m certain the failure was
hardware related. The mother board was at least 6 years old.
As I was in a hurry, I ordered a $10 USB to
audio dongle from Amazon.com and got it the next day. I
selected the DuKabel P8 USB Cable. There are many similarly
priced alternates with minor differences. Plugged it into the
computer and 10 minutes later, I was on the air with FT8. No
pain, no strain! Not an elegant solution, but significantly
easier than adding a new audio card to the computer, replacing
the otherwise adequate mother board, or attempting to repair
its audio input section.
