Joseph Salisbury, after reporting this bug I tried changing some
settings in alsamixer but it didn't seem to fix the issue.  Then, after
a reboot it started working although I didn't notice straight away so
I'm not exactly sure what has made it work.  This also happened on 13.10
-- i.e., it needed some encouragement before it starting working.

I've just installed and tested kernel 3.14-rc4 and the sound is also
working fine.

Once 3.14 is included on the daily LiveCD I'll re-test to see if I still
get 'no sound' on the fresh/clean image.
