I have a fairly large and complicated older multimedia program I have updated to Director 12 and I have everything working except:
My sounds - both background music and narrations - are simple sound objects placed in one of the two directly visible sound channels. Everything acts as expected both in authoring environment and from a projector when the sound card configuration for the computer is set for stereo sound. However, when it is configured for 5.1 sound there is no sound produced at all.
Is there a simple fix for this? At this point I am trying to avoid completely re-doing all of the sound handling into mixers, with which I have no experience and really little inclination to put further hours into this project.
