When I built my HTPC running Lite and connected it to a Sony TV with HDMI, I also didn't have sound initially. I was able to get it to work by removing power from the TV. Not just using the remote to shut it off, but actually powering off the power strip I have it plugged into. Waited about 30 seconds, powered things up and when the system started back up the sound worked.
While that may not work for you, it's worth a try.
