Hmmm, that's funny. I use a different volume module (umslider) and still get the same exception. :\
I can set the volume to a specific level and *then* use the up and down bangs, but something goes wrong with them once you're at zero. So... I can't help you, but I can sympathize. =P
UPDATE: Ok, I think I found the problem, assuming the v_bang source is similar to the umslider source. The snippet of code looks like so:
The volume is computed by
a) determining the balance (right/left)
b) changing the left channel volume, and then
c) multiplying left*balance to get right.
When left and right are zero, step a) causes a problem (0/0, balance not well defined). If none of the original module authors step in and fix this, I can update the code and compile a new version for you. And me. And anyone else who's been annoyed by this. =)
