The snippet of the dmesg indicates that the kernel was not built with the patch to /sys/conf/files. #!/bin/sh perl -pi.orig -e "s@(dev/sound/pci/csa.c\s+optional pcm)@#\1@g;s@(csapcm.c\s+optional) pcm@\1 csa pcm@g" /sys/conf/files diff -u /sys/conf/files.orig /sys/conf/files The perl command above will do the patch and print a diff. It should comment out one line and add "csa" to the next line. After running this, rebuild the kernel cd /usr/src; make kernel KERNCONF=Your_Kernel_Conf A reboot should show a clean probe line for pcm0 and no csa0. R.
