Isn't this an ALSA bug rather than a PulseAudio bug?

In Hardy, I could change my XPS 1530's built-in microphone recording volume via the control named 'Digital' in the gnome-volume-control 'Recording tab' (you have to enable it first via the preferences window). But in Intrepid there is no such control.

In Hardy, I can see this control in the /var/lib/alsa/asound.state file:

 control.32 {
  comment.access 'read write user'
  comment.type INTEGER
  comment.count 2
  comment.range '0 - 120'
  comment.tlv '0000000100000008fffff44800000032'
  iface MIXER
  name 'Digital Capture Volume'
  value.0 120
  value.1 120
 }

but this control is missing in Intrepid's /etc/asound.state file (which is created when I run /etc/init.d/alsa-utils start) and /var/lib/alsa/asound.state file.

This is with alsa 1.0.17. Hardy uses alsa 1.0.16.

I've also tried alsa 1.0.18 (http://ubuntuforums.org/showthread.php?t=962695) in Intrepid and it doesn't detect the capture volume either.
