What I am trying to solve, is the problem that people have with my snd-pcsp driver. Pulseaudio uses "hw" to bypass some pcm plugins, and then people are left with the non-functional softvol control, and they blame my driver. I am looking for the way to mandate the softvol plugin even for the "hw" device. Is this possible?
