I have conected my laptop vaio fz-15g win.vista.home.prem to a 42"LCD phillips 42PFL7422 with an HDMI cable.
Picture is perfect. No audio.
Laptop is configuerd to use HDMI out for picture and sound. Tried ALL soundcard settings and new/latest drivers. Even from 4th party sites, different manufactors altogether...
When running, The audio out on the laptop VOLUME LEVEL control has bars rising falling etc...
I _have_ bastardised the Nivida 8400mgt driver to get forceware to run.
Could this effect the HDMI audio passthru?
Please no suggestion to connect it to another HDMI source, I just don't have one. Unless I take the lappy to someone else's house. which is the next option.
