From my part the issue has been resolved, I am sharing this as a solution that worked.
Now this has happened before, a W10 Feature Update occasionally mucks up your connected devices (usually older computers with older connected devices).
Usually it is an issue with W10 installing new drivers thinking it knows better, and the whole troubleshooting / searching for correct driver method begins.
This time round though from my part the solution was a simple fix:
The USB DAC failed to recognize and sound was broken, in this case I just turned it off and turned it back on.
DAC recognises and functioning as before.Next the USB WiFi Adapter (which I have had many issues with in the past) failed to connect to the network (keep trying to connect to the same network and keeps failing).
I simply pulled it out of the USB socket, and plugged it back in. Now working as usual.
I just thought I’d share since this time round it was a simple fix, and this method may save you some time.
Good stuff for sharing this info and trying to help people out!!
What a nice thing to do! :)
