My apologies, it was me being silly (and forgetting a silly smiley ;-> ) -
High Definition is official; appearances are half-duplex.

If there isn't a need to input electrical signals and a built in monaural
microphone is satisfactory, the Phoenix Audio Duets act as complete
soundcard replacement with good sound  quality.  This has resolved problems
for us time and again.  Using the Duet we don't experience crashes with any
greater frequency than we do with legacy supported sound cards.

HD does stand for High Definition (despite appearances?!) - It's
referring to Intel new audio architecture:

I haven't managed to test RAT on an HD audio card as I haven't
currently got access to one - I'll see if I can find one....

I'm assuming this problem is being seen on Windows - anyone tried HD
audio on Linux?
