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.
