Because when I run Maverick (the upcoming Ubuntu release) from a Live-CD, the "PCM Playback Volume" control is still there (and there is no asound.state, neither in /etc or in /var/lib/alsa). When I use the plughw interface, the "PCM Playback Volume" does not affect volume output. Should I use another device string to test the softvol plugin, to see if it's there or not? Btw, I still think it's strange that a userspace plugin, with controls that only effects userspace, still can create controls in kernel-space.
