It is integrated in Lenovo Flex 2: "HD Audio, stereo speakers with Dolby Advanced Audio v2, 1.5W x 2 / monaural or dual array microphone, combo audio/microphone jack", Realtek High definition Audio.
On Sound/Playback devices tab i see only "Reproductors" icon when head phones are plugged in, so no multiple "devices".
