9800 gt compatability with Visio M420NV

[michaelb5452]

My tv is recognized as an hdmi connection in nvidia control panel, but windows audio settings does not list it to configure.
I have a lot of movies but I can't listen to them...?

ok. so my visio m420nv is audio compatible with ge 9800 gt! here's what else i found out today... my card is alive! i uninstalled drivers in safe mode and reinstalled driver 314.07... "nvidia installer cannot continue - this graphics driver could not find compatible graphics hardware. but wait... windows 7 successfully installed nvidia driver 306.987. Now here's the kicker: everythimg but audio drivers are installed, and again i am left without sound. HELP, i need a life preserver.
