Hi all,
        There are some Inel HDA codecs like ALC272 that inverse phase of one 
channel when capturing..
        remap_channels remaps stereo to mono by simply add one channel to 
another. the sum is always very very close to zero.

        ALSA works around this by using "copy" route policy for all Intel-HAD 
card which is equivalent with PA_RESAMPLER_NO_REMAP set in PA's resampler.
        
        Attach is a patch that set a REMAP flag for source when its underlying 
H/W is ALC 272. Then set REMAP flag for source-outputs associated with this 
source.


Cheers.
Long
