First, I haven't rebooted my amiga to test  the audio device yet.

However, If you're running -current and want to try Tim's audio device
there are two things to change.  One is that auconfig must *not* be
compiled with -DKERNEL, otherwise sys/types.h won't get included and
no types will be available.  The other is a generic problem with LKMs
in -current which I have described on current-users.  The quick fix is
to try this patch:

===================================================================

  	}								\

I hope the patch is clean, it's been pasted into an X-term with a
modem connection to work.  I haven't tried that file transfer protocol
before :-)  Then lkm_audio.c will compile cleanly.
