> but you can check that there is a sound module loaded at boot on a certain set of laptops, not too much problem.
How would one pick up laptops? And what about older hardware that may be still popular but it hard to get?
So I just do not see how one can skip user during testing. Surely with unlimited amount of time one can try to solve that problem, but with a more realistic budget spending efforts to simplify testing by users would be more fruitful.
