Hi Hans,

Fortunately I have three different laptops, all compiled out of SVN with
the following SVN revisions:

r214444  - micro of c910 does not work
r220692  - micro of c910 does not work

r226986  - micro of c910 works!

At the same time a look into SVN for uaudio.c gives:

$ pwd
/usr/src/sys/dev/sound/usb
$ svn info uaudio.c
Ruta: uaudio.c
Nombre: uaudio.c
URL: svn://svn.freebsd.org/base/head/sys/dev/sound/usb/uaudio.c

$ uname -a
FreeBSD vm-9Current 9.0-CURRENT FreeBSD 9.0-CURRENT #2 r220692: Sun Apr 17 03:28:12 CEST 2011     guru at tinyCurrent:/usr/obj/usr/src/sys/GENERIC  i386

this means:

1.
the last change of sys/dev/sound/usb/uaudio.c was done before
r220692, a revision in which it does not work;

2.
the problem is not in uaudio.c itself, but elsewhere in the kernel and was
fixed between r220692 and r226986;
