Comment 204 for bug 275998

It might be something to do with your /etc/asound.state file, which I think is created by alsa. I think I had to reboot a couple of times and possibly even run a configuration command before the new alsa recognised the digital mike control. Now there is an entry at the end of asound.state that says:

 control.29 {
  comment.access 'read write user'
  comment.type INTEGER
  comment.count 2
  comment.range '0 - 120'
  comment.tlv '0000000100000008fffff44800000032'
  comment.dbmin -3000
  comment.dbmax 3000
  iface MIXER
  name 'Digital Capture Volume'
  value.0 96
  value.1 96
 }

ie this is control 29 out of 29 controls.
