mac pro mid 2012 startup chime missing

Hi All,


I have just realised that my start-up chime is missing.


I have done some research & tried to get it back using Terminal & typing in the following :

sudo nvram StartupMute=%00.

However, this made no difference.


I also tried resetting the PRAM - but again, no sound.

Any ideas?


Many thanks in advance
