No Virtual Audio on Windows 10 Host

[luskin]

Hi All

I've just upgraded my host machine (ASUS K56CB - Intel Core i7 3537U - Chipset Intel HM76 [Panther Point]) from Win 8.1 (64bit) to Win 10 (64bit).
This PC hosts a Win 7 (32bit) guest that no more can produce any kind of sound.

It was all ok before host upgrading.

Any Idea??

ThankYou all for collaborating.

Luca
