Microsoft has chosen Intel® High Definition Audio (Intel® HD Audio) as the main architecture for their new Universal Audio Architecture* (UAA), which provides one driver that will support all Intel® High Definition Audio (Intel® HD Audio) controllers and codecs.
Which audio drivers should I have installed by Bootcamp support software for MBP mid 2014? Which actual audio hardware is present on this MBP - the Apple specs are vague on this point? Is it possible the Bootcamp support software has failed to reinstall the audio drivers correctly? One telling symptom - plugging in headphones doesn't show the headphone playback device as then being a connected playback devices as I'd expect. There are also a Microsoft system speaker device and nvidia audio drivers (for HDMI audio output) The installed devices I seem to have even after installing bootcamp are Microsoft High Definition Audio Drivers supporting playback devices for speakers, headphones and SPDIF.
