Thanks for your reply...
Getting through to Sony I don't think is even possible in a fashion that will make a difference . Sony USA's opinion is that the computer came with Vista.... and it should stay that way.
Under some pressure in Europe and Asia-Pacific, they provided I believe all drivers for XP (leaving a couple problems which most now can be overcome).... But in this case, the driver doesn't work properly in XP for HDMI audio output. Its hard to deny that the hardware is not there and working to use it ...Its just that their driver can't do it... The software for installing it is already present in the install package.... its just seems they either thru error or as a delibrate act have prevented a feature from working properly in XP. The video driver does provide HDMI video output.... just the audio driver is broken.
If features that are turned off can't be added to a driver if available, aren't all the modded INF's at for example Laptops2Go also in violation???
What about your own repackaging of drivers.... if somehow you now accidently allowed a certain driver to install on a computer that wasn't supposed to get it.... is that also a violation...
I know... I am preaching to the choir...
