SPDIF used to work flawlessly with WMC7 and Intel G620 integrated graphics. I only needed to set the SPDIF as default in the Via HD panel.
Since installing an HD 6450 video card I have to re-select this option everyday, or more if the HTPC stays in sleep mode for a long time. In fact the HTPC is always on & just goes to sleep when not used.
The other day I found an SPDIF setting in Control Panel > Sound and made it the default, but that made no difference.
Any suggestions on how to fix this?
