I have a new install of CS5 on a new PC with a new Blackmagic decklink extreme card. If I open a blackmagic timeline and add clips I can not hear any audio. I can copy the clips to a standard Premier sequence and they play fine but on the black magic timeline everything is mute.The meter moves but I can't hear it on the desktop. I have tried all he playback setting and various preference settings. Can someone enlighten me on how to set this up inside CS5?
