Does sound work in any other program? If not, check your audio output settings: system settings -> sound. Also make sure it's not muted.

+1 on installing the 64 bit version. You can even install 32 bit applications on 64 bit Ubuntu by installing the 32 bit libraries (ia32-libs).

Try running this:


Sudo apt-get install ia32-libs
