So, I have the card in the title. When I bought it, everything was hunky-dory (spelling?) I also have Astro's 2013 mixamp with a40 headsets (which WERE working) fine. Upon installation of the latest driver on creative's site, it seems that my sound no longer works correctly. Before, you would have to set "Speakers" as the default playback device, in order to use dolby digital live. Now, I only get sound when its set to S/PDIF, and I get an error message saying, "the operation was unsuccessful, blahblahblahnothing important" when i try to enable dolby digital live. Also, I am unable to get audio to go through the optical in jack. I cannot find the older drivers that i previously used, and I have uninstalled, cleaned, and reinstalled SEVERAL times, and I'm this close to just putting a hole in my monitor. please help.
