"Line Out CLFE" refers to the center/LFE stereo connector on a sound
card that supports surround sound. "Line Out" refers to lineout in
general without specifying the channels. I expect that hardware that
provides "Line Out CLFE" doesn't have a generic "Line Out" jack control
and vice versa.

This change has the effect that if the center/LFE connector is
unplugged, the lineout port becomes unavailable. This is not good, if
you want to use the sound card in stereo mode and have only the front
channels plugged in.
