Hi Chris !

These symbols are exported from the sound-core-module, which you have to
load.
Do a "depmod -a" as root to update your modules-dependency files.
Then load your driver again with "modprobe usbua100". This should load all
required drivers. If not, you have to list all dependencies of usbua100
explicitly in  /etc/modules.conf (man modules.conf).

An Object file is produced by the assembler, not the linker.
If you link a prog, the linker puts together the o-files if he can resolve
all symbols; in case of a kernel-module insmod/modprobe look if all symbols
are resolved.

No sound-core -> No usbua100 ->  no audio facilites ...
