This sounds exactly like the problem with my Hercules Game Theatre XP.  
What I'm pretty sure the problem is that there is an external amp (mine is 
in  the breakout box) that was not turned on by the driver, I figured out 
the bit to flip by looking at which bit the alsa folks flipped, then 
figured out how to do it in the FreeBSD driver.  So you'll probably have 
to figure out how to turn on the external amp for your card.
