[mythtv-users] SPDIF and HDMI

I'm setting up a MythTV box for my father.  He finally came around after him
and my mom were recording on VHS and it was just a pain.  So his TV only has
HDMI inputs, he bout a Nvidia 7300 with HDMI out.  The motherboard has SPDIF
out and the Nvidia card has a place for Sound in.  However, i can't get
sound through the HDMI.  At least i don't hear anything when i play a
recording.  I have a MSI 945GM3 motherboard  (

First, is it possible to get the SPDIF out to work with the Audio input on
the video card?  If so how do i go about doing this for all audio?  (at this
time he does not have like surround sound or any other way to get audio in)
and i don't know if his TV thinks the HDMI cable has audio, because when we
connect the line out to AV 1 Audio in on the TV, which the manual says to
use if it's a DVI to HDMI cable with audio separate, again no sound.  If i
plug in computer speakers to the line out we do get sound, so i know the
sound is working, i just need to know how to get sound to the HDMI cable
(all sound analog mostly since that's all he gets right now over cable
anyways).  Using a pvr-500.
