Comment 53 for bug 874535

I did what David said in #49

I run alsamixer
Flickers are still there but now Master, Headphone PCM and Front sliders do not change for full level (before they was going at full) and Front mic slider jumps.
Input Front Mic change to Line.

I checked again with hdajackretask, I confirm "Green Headphone, Front side, Jack detection Not present"

@Raymond
I don't have speakers. I have headphone on the green front jack and audio player on the blue line input, rear side. Nothing else.

Headphone is connected, but above still active "Green Headphone, Front side, Jack detection Not present"
