I have Windows 7 X64 installed onto my MacBook Pro 13 Mid 2012; I installed the OS using Boot Camp Assistant from within macOS, and installed the latest copy of the Boot Camp drivers (5.1.5621). Whilst all devices are working as expected, I've noticed that unlike in macOS, any audio that I play back through my speakers from within Windows sounds "tinny" and has no bass. My assumption is that only the left/right speakers are having audio sent to them, and the subwoofer is being left out of the mix - resulting in the somewhat flat sound. Does anybody know of a driver that I could use to replace the one included in Apple's Boot Camp driver set to enable this functionality? This version of the MacBook Pro appears to be using a Cirrus audio codec.
