When I ran the GENERIC kernel, message that stated I cannot load osscore.ko
module stated

Starting Open Sound System
osscore: Open Sound System conflicts with FreeBSD driver
osscore: Please remove sound(4) from the kernel or unload it
module_register_init: MOD_LOAD (osscore, 0xffffffff818b4010, 0) error 16
kldload: can't load /usr/local/lib/oss/modules/osscore.ko: Exec format erro=
r
Loading the osscore module failed

Maybe this weill be useful too.
