Hmm, in that case, something somewhere is busted.
Flat volumes will generally be able to increase your device volume but
wont decrease it.
Can you mail me a debug log from pulseaudio when you make the changes.
If possible can you replicate the problem using a PA mixer only? e.g.
start things running, then use pavucontrol to adjust the stream volume
(the playback tab, not the output devices tab).
The debug log will generally show the volume changes and ultimate what
app causes them etc.
It is however very strange that the master volume is directly linked to
the stream volumes.
Incidentally, I presume you are using a fully integrated phonon complied
with pulseaudio support? (i.e. the volume calls truely are going to
pulseaudio - using pavucontrol to change the stream volume rather than
amaork directly should prove this).
