Hello guys,
really struggling with this for a while...Sony or Panasonic tech guys have not been able to help.
previous LCD TV had no problems.
I'm trying to connect a sony media centre vgx - xl201 (running win XP) to a Panasonic TXL42d25b. LED TV.

Tried setting audio HMDI as default ouptput device (makes no difference)
The panasonic has 4 hdmi - tried all of them.
Tried other cables known to work.
Tried other equipment which produced sound.
Tried all options on sound configuration on tv...but still no sound not a beep!
Any Ideas- I'm no techie so plain language would help!!
Help pleeeaaaaseeeeee!!!!!!

What finally worked for me was completely deleting the NVIDEA HDMI driver, rebooting, and allowing a new driver to be downloaded and installed. Good luck!

I'm afarid that is no help, i've tried all setting and combinations in the control panel with no luck..
any other ideas??
Have you ever found the answer please? I have the same problem...
I got the same before. the fix is the setting on your TV. Try to look for an option at the "Aspect Ratio" and choose "Just Scan". Mine is a LG TV, maybe different in other TVs.
i had the same problem but I just turned off the tv then when I turned on again the sound already worked :)

I think the problem is some TV's need to be on that input while the computer boots up. If it's not, then it only pushes out display through the HDMI.
