[AG-TECH] Windows 7 64bits, cannot find audio device in RAT

    I had a similar problem. In my case, the hardware/software would not 
recognize input unless the plug was inserted *and* sound was on the 
left-channel. I had been connecting mono outputs to the stereo input on 
the computer and unless I directed the mono line to the left channel (or 
just combine outside the computer), input would not be recognized.

We discovered that at least with our particular hardware (HP Z800 onboard audio) that there had to be something physically plugged into the audio output jack before/while AG/RAT is opened in order for it to work.  If we opened the software before plugging in headphones, speakers, line out, etc. RAT wouldn't send anything through Windows, but you could hear any other sounds played from other programs... quite odd!  Maybe your hardware is similar where you need something plugged in before RAT is opened so it can detect it properly?  You probably tried this already but I just thought I would mention it, even though you described a different issue where RAT wasn't detecting any audio device at all.
