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.
