If there is a "Line Out" jack present, then add this path. The fallback
analog-output will be a subset of this path and removed.
I only use the "Line Out Jack" or "Line Out Front Jack" for actual jack
detection - without anything connected to the front jack, it makes little
sense to enable the port.
(Another option could perhaps be to use different paths for stereo line out
and surround line outs, but that could be a possible future improvement.)
