I having audio problems in Kubuntu. My headphone is not working correctly. When connected, no sound output and mic audio comes out of speaker. When I switch audio input, to "Internal Microphone"(Integrated Web Cam), the sound comes out normally from headphone.

My laptop is: Sansung Book E20 - NP550XCJ-KO2BR
Sound Card: HDA Intel PCH, in agreement alsa-mixer
Driver Installed and Used: Realtek ALC897, in agreement alsa-mixer

The problem not is headphone, he works in smartphones and Windows. In Windows, i used Samsung Update for update audio driver and resolve a audio problem similar.

Thankful for any help. And sorry, I am brasilian and i am learning english.

Welcome to AskUbuntu, you are saying that when you plug in to the headphone jack, system doesn't switch audio output automatically from speaker to headphone. And you want to set it so?

No, the system recognizes the headset, it appears in the system settings. What happens is that the headset has a microphone however for some reason it does not pick up the sound from the microphone but from the speakers of the headset.

3.5 mm mini plug

A 3.5 mm miniture audio jack has 3 types or more by length.
And the ordinary headphone jack is designed for TRS except the smartphone audio jack should be used for a headphone with mic and it must be TRRS.

Linux doesn't have a seperate driver for each one. See: What version of the Realtek Audio driver is my system using?

A USB headphone&mic adoptor can do this workaround. You can ask a new question or find the Q&A how you modifiy your own custom kernel to obtain a proper driver for TRRS audio jack.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
