I recommend updating the NUC BIOS to the latest version 0247:
Also make sure you have loaded the latest audio drivers: Intel® Download Center
Please check the link of tested hardware for Intel NUC
Thanks for your response. I completed all your suggestions - it has made no difference. I originally said I get no signal from any mic. this may be technically inaccurate. I think there is some signal but it is inaudable. I have just tried the same mic. earphones and cabling on an ASUS F401A this setup worked very well. So, my guess is that the mic. needs a pre-amp OR the socket is bad. Is there any way to find out the signal levels that are expected on the mic segment of the socket?
The tests on the NUC have been made with the mic. volume AND boost at maximum within the Realtek driver software.
When plug setting is: then:
MIC The microphone works, headphone speakers are off (Correct operation)
HEADPHONE The microphone does not work and headphone speakers are on (Correct operation)
HEADSET The microphone does not work and the headphone speakers are on (Incorrect operation)
In short I can have headphone speakers or microphone but not both
BIOS: 247 Audio Driver (from latest bundle May 2015, manually installed) Aud_Win7_8.1_18.104.22.16873
I have the same issue with my NUC (NUC5i5RYH). Up to date bios and drivers and no voice on input.
I tested it with microphone connected only (from headset working on my notebook and other computers without problems) and no any voice is on input (although whan I connect jact to NUC it shows dialog with option to point out mic and I do it and see it in windows and skype).
But when I say something no any voice is presented on bars or recorded on skype or Realtec ui.
I bought also some headphones with microphone connection integrated in one jack (Sony MDR-ZX110AP) and it doesn't work also (microphone function).
Any idea what is going on there... ???
Does Intel monitor this community?
Can anybody answer if they are successfully using a headset with the NUC5i5RYH? Are we talking about:
- A hardware problem requiring a RMA
- A TRRS plug (or socket) out of specification
- What is the expected impedance of the MIC at the jack? My headset (Sennheiser HMD 26-II) is 265 ohms DC (Pin 2) to ground and specifications are 300 ohms AC. Does it need an impedance transformer?
The headphones L and R channels are clear - working correctly
The MIC is very muffled.
