On my CentOS7 system, it’s either the libcanberra-gtk2 or libcanberra-gtk3, but I bet on centos6 it’s just the gtk2 one. You probably need the 32-bit libcanberra-gtk2 package. Repeat with pk-gtk-module. The problem is that it’s not strictly Required for Skype to have the entire 32-bit graphical environment installed, but it appears that it’s necessary to have parts of gtk installed as 32-bit. -- Jonathan Billings <billings at negate.org>
