I would say this is more that driver issue my dear @bescouted. You see, when a company makes drivers, however complicated they are, testing must be a part of a process. Since they want to maximize profits, they have to test it with the most common OS in use — which Windows 7 still is. And when they put up unworkable drivers leaving their customers without a clue, it can be qualified anywhere between gross negligence and pure insolence.
Kev333 put this solution 4 moths ago, and M-Audio still doesn't have any note at their drivers page, as you can see.
Thank you very much for your support.
Damn, I've just looked it up and found out that Windows 7 is still really widely used. They might still make up the 30% of all windows installed in the machines. This is crazy I thought they total up to Max 5% or less. In this case it is really negligence.
Designers of the Win8, 8.1 and 10 should be jailed :)
