The module-tunnel-sink module should take a rate= argument. There is no
GUI tool to configure this, but if you enable it via paprefs, you can
hack it into the mix using gconf-editor (for now at least - I am
intending on changing this eventually).
FWIW, some kind of tunnel compression technology has been mooted in the
past and will likely eventually make it's way into PA, but there are
several other things that are further up the priority list, so I
wouldn't hold your breath for too long! :p

You can use it, but you have to use the numbers 0-9... for some unknown
reason (read: no ones really be bothered enough to seriously look) the
arrow keys don't work!
"amixer set Master +10%"
Should get your your volume adjustment.
