I upgraded from Suse 10.3 to Suse 11.0 on Thursday 6/26/08.   The kernel changed to 2..6.25.5 and with it the /dev setup for the sound.  /dev now has a subdirectory of snd instead of audio with the pcm dev units and controls. 

Everything I had before stopped working.  I've been through the /etc/modprobe.conf file and and readded the usb product and vendor id numbers, modprobe and lsmod show that snd-usb-audio is loaded and /proc/asound/cards show (I think) the right information, but amixer says there is no audio cards at all. 

Is anyone willing to help me troubleshoot this off list?
