First of all, I never said that a transformer is not bidirectional. That is only in your mind.
So you can test both ways BUT your method is just an alternative way to test, not better, not easier. It also has shortcomings.
For SE you must have a bias current, if you make measurements at high, higher volumes you will even make the wrong measurements if you do not have the correct bias current.
With a sound card the options are quite limited. Decent frequency measurements are only possible on a modest scale. For someone like me who wants a really good transformer it is unsuitable.
For simple and good equipment i prefer a Analog discovery 2
