commit e4efa82660e6d80338c554e45e903714e1b2c27b upstream.
This is a Lenovo ThinkStation machine which uses the codec alc623. There are 2 issues on this machine, the 1st one is the pop noise in the lineout, the 2nd one is there are 2 Front Mics and pulseaudio can't handle them, After applying the fixup of ALC623_FIXUP_LENOVO_THINKSTATION_P340 to this machine, the 2 issues are fixed.
