Sharp aquos 42"

I connected a Sony Vaio notebook via hdmi. Perfect picture but no sound. The notebook works perfectly with other TVs, so I don't think it's the computer settings.

Check the settings in the TV set for HDMI sound on the input of the TV that you are using. Try another HDMI cable. It may be defective.

It is also possible that there is a compatiblity problem for the HDMI sound between the TV and the computer's sound protocol.
