Hello Jian,

I can assure you that the process works, many many people do it and works.

So, we need to find the error.

1) are you sure you have moved away the correct sound modules
directory? check with "uname -a" to know which kernel are you using,
and then move away the sound directory under the correct kernel
directory (you may have more than one kernel and modules installed)

2) you really have to move that directory away, not rename it in place

3) are you sure the ALSA drivers were correctly maked and installed?
Also, don't do the depmod on the command line if you are unsure you
are using the correct kernel in command line (make install will do the
depmod for you, the second one is just a little redundant)

4) if still fails to modprobe:

a) find all the sound directories under the kernel you are actually
using and move them away or delete them
b) delete the /usr/src/alsa-drivers directory
c) do the tar xjf again on the alsa-driver archive you downloaded
d) do configure - make - make install - overwrite the dummy.c with my
dummy.c - make - make install
e) reboot
f) modprobe snd-dummy

Let me know how it goes.
