FWIW, the messages are coming in, but I don't do pulse-audio at all so 
can't help with it, my main machine plays (digital output, kmix doesn't 
do anything anyway) thru my home 5.1 system so has plenty of volume, and 
while my netbook sound is a bit soft, I'm not using it enough for that to 
have worried about it.

So at least here, not much I can suggest...  As it seems I'm one of the 
more active regulars as well as one of the more technically inclined 
regulars, unfortunately, the lack of response could well mean no one else 
has a clue either.

Meanwhile, while I don't know much about pulse audio, I do know a bit 
about audio in general and computer audio in general, and it seems to me 
that if pulse can be set to further boost volume in software, as we see 
gnome doing, there's a good chance that you can configure it to do so by 
default, regardless of the client used to control it.  But you'll likely 
have more luck researching either the pulse documentation or googling it, 
or asking on the pulse-audio lists or forums, which I presume they have 
tho I've no real idea, personally.  Barring someone stepping up here 
right away with more info, that's where I'd be looking next.  Try googling 
on the three terms "linux pulse gain" (without the quotes as that would 
try to match those specific words in that specific order).

I hope you find a working solution.
