Scenario.
PC (nvidia 7600gt) used to be connected to HDTV via DVI to HDMI and the sound was carried by 3.5mm jack (speaker output on PC) to 3.5mm jack (PC audio in on TV)
Everything worked fine and dandy.

FF to today. Installed Nvidia 9800GT picture goes via the same DVI to HDMI cable but there is no sound.

The Audio cable is OK (checked)
Audio output is OK (checked)

Cant use RCA sockets as the TV only accepts PC audio in when HDMI is selected (TV doesnt have VGA D-Sub)

Could it be that it used to work because the 7600gt was pre HDCP GC and the 9800gt is HDCP and that the HDCP side of things is switching off the PC audio in because it wants the audio signal over HDMI and no other source (expecting that if no audio is supplied over HDMI then audio will be supplied externally)

Any idea's.

Thanks

Al

TV is a Tecnika 26-107 720p
GC is xpertvision 9800GT
