laptop speaker is working but headphones jack no

[Dedalus1983]

Hello everyone, I use Ubuntu-Gnome with kxstudio repos on my Dell Inspiron laptop.
I was doing all right, I was beginnig to explore audio-linux world
Then, I upgraded Ubuntu from 14.10 to 15.04 ..
Since then, laptop speaker is working but headphones jack no!
I am running a lowlatency precompiled kernel, with Jack and Pulseaudio bridge.
Since I am a beginner in some way to audio configuration in Linux, can you help me in finding where is the problem?
Thanks!!!!

I am also having the same issue as Dedalus1983 or luca. I am not new to linux but I have been away from the community for awhile but I am now back. I have a Toshiba Satellite Radius 11 with 15.04 with Gnome installed. I know the port works when I had windows 8.1 installed but I had a difficult time trying to get it dual booted so I just went full linux. When I plug in my headphones while there is sound, it continues to play in the speakers but not the headphones. I am not sure what's going on here but I will continue to research. Any input would be greatly appreciated, thank you!!
