pulseaudio use "Line Jack" to determine whether line in is available or not
In 8ch mode, do the "Line jack" return true when you plugged "Side Speaker"
should "line in" list as not available when channel mode changed to "8 ch" ?
Should changes in "channel mode" , "Headphone Mic jack mode" or "Mic Jack
Mode" trigger an event so that pulseaudio server probe the sound card again
There is still bug in the patch
should check (cfg->line_out + spec->multi_ios) >= 3 instead of
spec->multi_ios > 0 so that the channel mode is not added for notebook with
line out and mic jack
