yes, you are right emu10k1 here:

hehe .. this sounds to be looking funny ... ;-)

well, in case of the  emu10k1 (using hw) just 2 hardware ports are detected: 1 
stereo input and 1 stereo output.

using plughw there are just a little bit more; just one too much ... ;-)

... I mean there are 2 stereo output connectors, 2 inputs (1 stereo in and 
the microphone in) on the sbLive and also the midi connector as well which 
maybe is the mistereous 3rd in ? ... don't know ... just a guess ... 




There is also a problem with plughw, since the TPA shows that the 1stOUT is 
used, but the console message is different:

and when I manually choose 1stOUT the machine hangs!!!!! :-(




and finally record don't work. neither with hw nor plughw.
below id the output using hw when ^T<A>:
