I'm trying to watch my Battlestar Galactica Blu-Rays on my PC, using Cyberlink PowerDVD Ultra HD 7.3 (fully updated). It plays the audio on the menus fine, and the audio for the Universal logo at the start of every episode, but as soon as the episode itself starts playing I get a loud buzzing noise which is then replaced by static. The audio commentary track works fine. I figure it's something to do with my onboard Realtek HD Audio, as it worked fine when I had my X-Fi card installed. Someone on the Cyberlink forums who had the same problem was told it was due to DTS not being supported by their soundcard, so I tried the cracked Realtek drivers found here but did not have any improvement. Do I need to go back to my X-Fi or another Creative card I have? I stopped using it because the drivers were buggy and kept flaking out on me.
