For example, on my card  I have 25 sliders/buttons. I have absolutely

idea what most of them mean, nor any idea where I could find out what
they
mean.

Since ALSA has to expose all the hardware details, I think the best
solution is to do what the Gnome mixer does, and hide all but the most
important ones by default.

The best solution would be to define ALSA HAL (not just API) first,
along the following lines:

A general coundcard is:

1) user-accessible connectors which can be inputs, outputs, inouts, analog
and digital;

2) a there may be connectivity matrix connecting the above connectors with
ADCs, DACs, DSP ? (let's leave it for a time being), so each card should
be accompanied by a machine-readable description of the connectivity matrix;

3) there should be machine-readable description of ADCs' and DACs' sampling
rates, per input connector if necessary.

Etc.

I'm just giving a direction of thinking.

With existence of properly defined HAL per card mixer generation (with 
meaningful
control names) should become trivial.


Easier said than done when so much of the driver support had to be
reverse engineered.  We don't even have this info for a lot of hardware.

Yes, that the alsa support is there is pretty amazing and huge kudos are
deserved by a few people who have put in a huge amount of work. Thanks.
