Hello:
Sorry if this sounds a bit naive, but I've never encountered a problem like this before. I just assembled my NUC D54250WYKH with the latest BIOS and drivers (as of 1/1/15). I've also installed Windows 8.1. Everything works wonderful, except the front audio headphone jack. The Realtek audio is present as a device in Windows, but (as has been documented many times before) does not show anything to configure until I plug something into the jack. Well, I just plug a small speaker or headphone and get a pop-up box that gives me options to choose whether I have plugged in a "microphone", "headset", or "headphones" (but not speakers). However on the Realtek configuration page - I now can configure speakers, but there are no options to configure headphones. I can see no headphone options. This would be fine, but it doesn't supply any signal whatsoever.
I tried plugging in headphones and get the same screen - to configure speaker output - from which there is no audio signal. Now all I want to do is use headphones with the NUC. I'm not looking for anything but a simple analog signal. I've even contemplated using an HDMI to HDMI + 3.5mm audio splitter just to get an audio signal out of this thing.
What could I be doing wrong?
A second question (related to the first) ..... In desperation I tried to use Bluetooth to connect to a pair of Bose Soundlink speakers. No go there. They will both pair with the NUC fine, but I can send an audio signal to one of them only (the first one that I turn on). Windows tells me that there is a second Soundlink speaker connected but will only deal with one Bluetooth device at a time. I assume this is a Windows (8.1) issue - but is there any way around it.
