Further on the subject of playback vs capture vs other...
Of course we do have controls that are obviously "Playback" or "Capture",
however we also have controls that connect PCM out to PCM in i.e. both
Playback and Capture are involved,

"PCM0 to PCM1 Playback Capture Volume"  .. nooo!
"PCM0 to PCM1 Loop Volume"  ???

and others that connect linein to lineout ie. neither Capture or
Playback involved.

"LineIn2 to LineOut3 Volume"
maybe "LineIn2 to LineOut3 Loop Volume" ?
