I have a Win10 Pro x64 PC to which I’ve attached a Dragonfly Red via a USB hub. I had been listening happily for months to my Roon Core (version 1.6, build 416, stable, 64 bit) on a separate Win10 Pro x64 PC. Last night I updated the PC with the Dragonfly to Win10 Pro 1903 (OS build 18362.388). This is a major OS update.
Today I noticed that the Dragonfly was no longer presented by Roon in my zones. I uninstalled (via Windows Device Manager) the Dragonfly, rebooted and reinstalled the Dragonfly. Still no Dragonfly in Roon. Finally I went to Roon/Settings/Audio and found, under “Connected to this PC,” Dragonfly Red but not enabled. After I enabled the Dragonfly, all is good.
I’ve seen this sort of disappearance in the past. Any idea what’s happening?
