I have just installed Lucid from the alpha 3 image, applied all updates and
tested the workarounds:
- The solution given in comment #30 *does* work (this amounts to 2 lines
added to the alsa/cards file).
- The solution given in comment #63 (#52) *does* work (I am using this one in
Karmic, so I just copied the files over).

How about fully specifying all subsytem IDs instead? E.g., the following
/etc/udev/rules.d/ice1712-pulseaudio-workaround.rules would work for everyone
subscribed to this bug who has reported success with this approach, and
should not affect any other card:

Some subdevice IDs and card names are from http://envy24.svobodno.com, as
usefully linked in comment #80. I have tried this version of the file and
it works. This of course should go with a matching
/usr/share/pulseaudio/alsa-mixer/profile-sets/via-ice1712.conf
as indicated above.
Would this be a suitable solution for the time being, until ALSA and/or
pulseaudio
fix the cause upstream?
