Thanks as ever for your time and insights Tanu. Deeply appreciated.

Forgive the confusion. I had not intention of alluding to a change in 
card name per se. I mentioned the idea of a localname only (not meaning 
to replace a name or id or any other property that already has meaning 
and function in some context but as a place to store a name that can be 
edited by the system admin to read meaningfully for a given card/port to 
users of the current system).

It seems that description is intended to fill that need, so totally no 
need for another property like localname.

It seems from what your saying that:

a) providing such descriptions from the lowest level not the highest,is 
desirable so that consistent descriptions reach all apps and efforts are 
not duplicated.

b) pulseaudio already has the infrastructure for saving and remembering 
such descriptions and ALSA probably not. So pulseaudio may be sensible 
place to see it implemented. Such features may even be a feather in the 
cap of pulse.

c) at the pulseaudio level there are already description properties 
available (on sinks, cards and ports) and all it would take to allow 
tweaking them is an interface of sorts (update-sink-description, 
update-card-description, update-port-description?). Not sure if these 
stored descriptions survive the unplug, plug scenario mind or if they 
are overwritten when replugged.

It seems to me that on MINT at least the Sound settings and the System 
tray sound app list output devices differently (superficially it looks 
like one lists ports the other sinks).

Either way, I'm curious if pulse publishes a document or spec which 
stipulates what the expected (planned for) manner of describing sinks, 
cards and ports in apps is, in order to promote consistency?

Bernd.
