XINE with no sound

I downloaded and compiled the xine/xine-ui 0.9.9 sources yesterday, and it works well on the video end, but no sound :( i didn't have my sound configured on my box when i compiled it yesterday, so i uninstalled it, configured sound and reinstalled it, but still no sound. when i click the volume bar in the UI nothing happens. i got this to work on my other box with sound without any tweaks, but not on this one. anyone have suggestions? sound card is a SB PCI 128 (i know, it's a POS), and i can hear sound from other apps (xmms). thanks, Jason
