[alsa-devel] [PATCH] Line In for Acer Inspire 6530G model

[Tony Vroon]

The Line In connector is set up as PIN_IN by default, using 
VREF_HIZ. It is connected to both ADCs, so add it to both 
input selectors.
Also add the ability to use the input mix (on a SoundBlaster 
one would call this "What You Hear").
