/dev/dsp is Open Sound System specific. Ubuntu 12.04 does not faire well with Open Sound System (although I've got it working on my laptop, just for testing). But this is really OpenAL telling it can't find any output devices. You could try running openal-info but I expect it will also show no output devices in which case Linux does not seem to find your hardware somehow.

That should not happen.
