edited - had to think about it and then I had nothing.
Essentially it was using a cord to plug the line outputs back into the line inputs of the sound card and having the microphone into the microphone input with the volumes up to record via the mixer in the OS of the computer. Unless using a Y-connection cord to have speakers hooked up or a headphone you would not hear it on the line outputs of the sound card using the Y-connection cord to have two connections for the output of the sound card. Then the complications came if having to play the Karoke file and then trying to record it which probably would not work having two programs running like that at the same time. Involves using the same sample rate and bit depth perhaps or drivers. So it ended up maybe not being possible or at least messy perhaps.
I think I did it once or twice like on a utube video or file that way but then you can not hear it, so in the end you would not hear it and could not add a singing part to the karoke file.
You could probably sing along with the kakoke file playing, but then could not record the singing, just sing along with the file.
Then you could probably get into mixing boards and connections and end up using more equipment unless you could get the signal internally in the sound card with the microphone to avoid using funny connections or trying to do it with more recording equipment like a mixing board whatever.
Sounds complicated then and essentially comes up to be nothing in the end. But thinking about it is an exercise for the brain just to do for perhaps a few minutes.
Weird idea day I guess.
