There is a related case that I mentioned a long time ago. I had a
Creative X-mod USB card (I sold it, so I can no longer test this). It
has a big round volume knob that I thought would be nice to use to
control the volume of the sound coming from the device.

But no, the volume knob doesn't do that. I simply acts as a keyboard and
sends increase-volume/decrease-volume keystrokes. This means that it
would usually (depending on how I configure things) not control what
comes out of the Xmod, but instead control the main volume (which are
the internal laptop speakers or headphones.

The workaround was of course to make the Xmod the "main" device, and use
the internal card as a secondary. But I was really annoyed by this
misdesign.

Could this be solved in PA somehow?
