This is a well-known change that really isn't PA's fault; it's really
the OEM's but unfortunately affects everyone else downstream in the
supply chain.

See http://bazaar.launchpad.net/~ubuntu-core-dev/pulseaudio/ubuntu/annotate/head%3A/debian/patches/0090-use-volume-ignore-for-analog-output.patch
for my change which allows you to work around the symptom.

It will not ship in Karmic final, because it will break a far larger
number of users.
