Intel Fixes Netflix DD+ HDMI Audio Issue
If you use Intel HDMI audio with the Windows 8.x “Metro” Netflix app you know that Dolby Digital Plus (DD+) output has been broken for, um, forever. Thankfully, they just released an updated audio driver that solves the issue! Huzzah!
Unfortunately at the moment it looks like they’ve only updated it in the Ivy Bridge GPU driver package for the NUC, so it won’t install easily if you’re running something newer. That said, there’s no reason why you can’t download the driver, extract the ZIP, then fire up Device Manager and manually update the Intel Display Audio device driver (it’s under Sound, video and game controllers). That’s what I did :).
