CT4831 SBlive! Value not working

I just installed a new sound blaster card.
I disabled my on-board audio in the bios
I ran alsaconf and the onboard audio still shows up as VT8233/A/8235/8237 AC97 Audio Controller
I configure the sound blaster but no sound plays not even a test sound
and sound still comes from the onboard but not the soundblaster

update: when switched to another user sound comes out of the SBLive! but not the on board
