Thank Capriccio for the following information.
The skype can be worked properly now.
1. backup your existing /etc/modprobe.d/alsa-base
2. append the following to the end of the file:
options snd-hda-intel model=ref
3. reload your modules or reboot.
4. Audio system set to "OSS" in the skype option.
But Gnome-Media sound-recorder doesn't work yet.
