Hi, Sound work perfectly on mac OS, No sound on Windows 7
Did you download and install the Windows Support Software (in Boot Camp Assistant) and then install it in Windows?
i downloaded and install boot camp windows7 version, high defenition audio device showing working properly, no esclamation marks in device manager, still no voice
Is this the software downloaded from Boot Camp in OSX?
Sorry, I see it is, remove the driver (Windows Device Manager) and then restart Windows.
