Hi,

I had a problem with muting speakers when headphones are plugged-in on my  
Benq S32B. So I added proper board configuration to  
sound/pci/hda/patch_realtek.c and now it works.

I wonder if anyone has similar hardware (S-series Benq laptop) to test the  
patch (attached) if you find it useful.
