Up(?)graded to W10 and I cannot get my speakers to work. I have an MSI MS-7681 motherboard with Realtek High Definition audio built in. I downloaded the latest driver, which is supposed to be W10 compatible (Ver 6/18/2015). When I go to control panel>hardware & sound>manage audio devices>speakers - Realtek High Definition Audio>configure>test, I can hear all (7.1) the speakers just fine, yet I cannot hear music, computer sounds, internet video sounds, or anything else. Help!
