Capture controls affect audio data that is recorded by the computer. Playback controls affect audio data that comes out of the sound card.
OK. I think everything fits one of these two.
I find the asymmetry a little odd. (i.e. Capture controls defined by destination of PCM Capture, while Playback controls not defined by source of PCM Playback)
In both cases, it's the destination that determines the type.
When it comes to partitioning the controls into two groups according to overall direction, using the destination makes the most sense in practice.
Yes, basically this is a heuristic mapping to the traditional mixer interface. Not all components match properly, indeed. We need either give compromised element names or implement something new...
I.e. in reality they are "Capture" and "Output"
Yes, but this naming convention is already there for hysterical raisins.
Still better than angry grapes :)
