@mmifas, About your comment "When I plugged in the headset, sometimes sound coming though both. I can configure in alsamixer", in that situation, the sound is supposed to be played through headphone, so could you please generate 2 alsa-info.txt, the first one is generated when problem is reproduced, the second one is generated after you use alsamixer to workaround this problem.
