Run a mixer of some sort and see if the input/outputs are muted and unmute them if so. Otherwise, post the same output from lsmod on the working ubuntu setup.
The future appears to be RHEL or Debian. I think I'm going Debian.
Info for USB installs on http://wiki.centos.org/HowTos/InstallFromUSBkey
CentOS 5 and 6 are deadest, do not use them.

Hello, I'm sure it's not a mute configuration problem.
How can I get the corresponding driver? I want to compile and install the driver manually
