I'm looking on answers how to solve this problem since I got this laptop. This is the newer version of lenovo b580 (the one with i3 mobile). It has a single combo-jack on the side, and I cannot get it to recognize my microphone (tried it in windows 7, 8, 8.1 and now at 10).
The audio card is:
HDAUDIO\FUNC_01&VEN_10EC&DEV_0269&SUBSYS_17AA500A&REV_1002
And the system identified it as Realtek High Definition Audio card. I can also see in the device manager two other devices – a nvidia one, and a "HDA Compliant Standard Device" (sorry if I translated this incorrectly):
HDAUDIO\FUNC_01&VEN_8086&DEV_2806&SUBSYS_80860101&REV_1000
And a nvidia audio device (probably related to my Nvidia Optimus setup):
USB\VID_0955&PID_9000
In the recording devices tab i see:
The bottom one seems to be my laptop built-in microphone (based on trial-and-combat with woobling my finger against it). The top one seems to be what SHOULD be my combo-jack, but it keeps saying "Not connected" (the bottom one was disabled by me, for some tests, turning it on doesn't change a thing).
I've found some forum posts that told me I should be prompted for a 'connected device type' from realtek, but I have never been. There is also no option in the realtek control center to enable the mic, or to change the device type. This is all I see in realtek audio manager:
Uff, that's a lot of information. The question is: how the hell can I get this to work?
I do own a kind of "splitter" that looks like this: https://forums.lenovo.com/t5/Displays-Options-and-Accessories/Microphone-Headset-Jack-splitter-needed-for-combo/ta-p/256059 but just connecting this doesn't do the trick. There has to be something wrong with the configuration/drivers.

There are two different headset connectors and they are not compatible. but unfortunately, AFAIK, Lenovo uses both. So instead of messing with drivers, you may want to try another headset.
