Introducing a /proc/asound/card0/pcm0{p,c}/hw_limits or similar might not be
a bad idea though?
That would be good idea, with completion with 'alsainfo' about device.
How to do that properly, any clues before I try to sink my teeths in ALSA code?

Current sample rate only has meaning with the device open , and if I
understand you right, a cat /proc/asound/card0/pcm0{p,c}/sub0/hw_params
will then get you what you want as to the get part (substitute for 0 in

You might consider this less of of a hack -- it uses the ALSA API to query

Only if you promise to never drop CCs again (although I don't know about
plugins).
