No, of the hardware.

Not always. When I wrote the RME driver for the digiface/multiface/digi9652 etc, I knew that status bits were available, but I don't recall exporting them to user space. At this point in time, I don't even remember what the ALSA abstraction for that would be. The "control" device? The mixer?
