I can no longer record any sound coming through my sound card - only from microphone input. The option 'Rec. playback. IDT high definition audio codec' has simply vanished. I'm baffled and have tried everything. Drivers
appear to be OK and up to date.
I've included snips of the dialog box as it used to be (left), and the way it is now (right). (I've right-clicked and checked 'show disabled devices' and 'show disconnected devices'. )
What may have caused the problem? Hard to say as I haven't tried to use this function for a few days. but possibly... Audio software which i have installed, then uninstalled, or new version of Skype, might have changed settings? Or I've 'cleaned up' too aggressively and have deleted something important?
If this is a 'silly' problem, apologies; but as I say, I've tried everything. please help.
