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?
