I have recently installed Fedora 21 Mate on my desktop which runs on Intel DG41CN motherboard with Realtek ALC662 Audio. Prior to this I was running Linux Mint. It was working all fine then, I may have fixed it when I had installed Mint two years ago but I do not remember what was done then. I also run Windows 7 on the same machine and there is no problem with the audio.

So the problem I have is that there is no sound from my speakers. A few times, there is a little "choppy" sound but thats it. When I put the headphones on, the sound is there.

I must also mention that I also installed Ubuntu Mate on it and faced the same problem.

I have run the Alsa diagnostic tool and the output is uploaded here: http://www.alsa-project.org/db/?f=1f6dd98e26f68e890258fa2fe5eb08ee343c5c13

I will really appreciate any help. I am stuck bad here..
