After you have installed ALSA, you need to reboot the machine, or to rmmod all the snd* modules from the kernel, before to modprobe snd-dummy
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. -giovanni
Now I am getting exactly the same problem as if under virtualBox or VMPlayer. So it's not a VM problem. Please help! Thanks! Jian

Hi, I tried real machine. Got different error: FATAL: Error inserting snd_dummy(/lib/modules/2.6.24-26-server/kernel/sound/drivers/snd-dummy.ko): Unknown symbol in module, or unknown parameter (see demsg). Then if I type demsg, got the attached screen. Please help. Thanks!

Tried under VMPlayer, got the same problem, will try real machine later. Attached is the screen shot.

Maybe is a problem with virtualbox. Also, is known that fs+mod_skypopen+skype clients does not works in virtualbox.
Try it on a real (hardware) machine.
Or (but is less popular) in a xen like virtual machine.

Hi, I am trying to follow this wiki: http://wiki.freeswitch.org/wiki/Skypiax_Skype_Endpoint_and_Trunk to setup FS and Skypopen on Ubuntu 8.04(64bit server inside virualbox).
There is one step asks me to build snd_dummy:
http://wiki.freeswitch.org/wiki/Skypopen_Skype_Endpoint_and_Trunk#ALSA_and_t... The section is like below:
Ubuntu, Debian
Note, Ubuntu may have alsa sound drivers installed at /lib/modules/<your kernel version>/ubuntu/sound/..., you may need to remove the dir to allow modprobe search from the default place: /lib/modules/<your kernel verision>/kernel/sound/ (don't forget to rerun /sbin/depmod after removing the old sound directory. Eg: /sbin/depmod -a 2.6.24-24-server).
./configure --with-redhat=no \ --with-cards=dummy,usb-audio,hda-intel,hrtimer,rtctimer \ --with-card-options=all make && make install
After the first make && make install, copy mod_skypopen/configs/alsa/dummy.c to alsa-driver-1.0.20sound/drivers/dummy.c .
make && make install #again :)
The problem is after I did all of them, when I entered modprobe snd_dummy, it always crashed and returned as "killed" on my terminal, I could see it dumped out a huge block or data(numbers, etc) on the host but don't understand the meaning. While if I used the original dummy.c inside alsa-driver-1.0.20, it worked fine. Besides, the default ubuntu installation doesn't include kernal dev and source, so I did one more step(or it cannot build alsa).
Did anyone try the same and get it working?
Thanks! Jian
