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"
?

pactl list

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
