If the live CD allows you to do this, run sshd, set a root password and log in
using ssh from another machine.

It might simply be that the volume settings need to be changed. First, run
aplay -l to find out for sure which cards have been recognized. You should be
able to use amixer to change the settings (e.g., to increase the volume).
Other programs that may help are:
lshw to obtain hardware details, and lsmod to find out what kernel modules are
loaded - there should be one for each sound card, plus the Alsa modules.
