[LAU] what have i done wrong here.

hey crew. not sure what i have done wrong here. i upgraded my kernel from 2.6.23-rt1 to 2.6.24-rt1 and i have lost my sound. i'm using a rme multiface and an onboard intel. the .config file is virtually exactly the same and the modules load, the hdspmixer loads and sound appears to play "into"(as i can see levels on channels 1+2) when hdsp mixer using jack but not out alsa(no levels on output of the mixer show at all), and alsa doesn't work at all. however, the onboard intel work fine(alsa and jack) when the multiface is not plugged in. i've probably missed something really simple but i can't put my finger on it. kernel 2.6.23-rt1 http://pastebin.com/m6e0c4c43 kernel 2.6.24-rt1 http://pastebin.com/m4beca721 any suggestions welcome.. ta. t gentoo with pro audio overlay
