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).

...
  I'm a bit stumped here because I don't
understand how the .o file can be 
 prduced if there are un-resolved sysmbols. 
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.

...
  I also notice I have no audio facilites listed in the
Mandrake Control 
 Centre. Does this machine believe it has no audio, and could somebody 
 please elaborate if at all possible? 
No sound-core -> No usbua100 ->  no audio facilites ...
