[Freeswitch-users] skypopen: problem loading the custom alsa driver

[Giovanni Maruzzelli]

Are you using a normal ubuntu installation? I mean, the normal stock
kernel that Ubuntu gives you?

Do you have done:
apt-get install linux-headers-$(uname -r)
before to do the alsa things?

If not, please delete all the alsa sources directory, decompress the
package again, and start from beginning.
