I got another i386 Ubuntu 12.04 machine and on this one sound fail. This time i notice one issue in the log:
------- sound initialization -------
... EAX2.0 not found
... using 0 channels
sound sampling rate: 44100Hz
------------------------------------

------- use sound driver "joal" -------


So from the looks of it EAX2.0 is required if you want sound.
