Do you get sound from the external speaker port

No, that's dead silent as well.
Hmm... Try a PRAM Reset. Reboot the machine holding down Command(Apple)-Option(Alt)-P-R
Do it 4 or 5 times for safety. It might just be the volume setting int he PRAM is
confused.
If that doesn't fix it it's almost certainly a failure in the audio section on
the board, possibly a blown cap something similar.
There is also something called a PMU or CUDA reset button somewhere on the motherboard,
which may be a last-resort option. You need to be careful about pressing this as it should
not be pressed more than once (I vaguely remember something about possibly damaging the
motehrboard if you press it more than once).
I had a PowerMac G5 which just died after being switched off for a couple of weeks while I
was on holiday. As it was bought in Norway, it was covered by a 5 year warranty
("reklamasjonsrett"), so an Apple authorized repair centre spent a lot of time
and spare parts trying to get it working again. They eventually gave up, and Apple gave me
a brand new Mac Pro as a replacement. A happy ending, but it completely soured me on the
G5 PowerMacs.
