I'm using Windows Vista. I can not get a digital signal out of the SPDIF out plug on the back of my computer. I have recorded through the spdif in okay. I'm playing a song with Windows Media Player. I think I just don't have the computer set to send the digital signal out. I've gone into Control Panel's Sound and audio section, but haven't seen anything that looks like it would send digital signals out. Any help would be appreciated.
