I'm having the exact same issue, but changing the Dynamic Range in the game to Headphones as was suggested hasn't solved the problem for me. I've tried to find a way to implement the other solution of changing Windows to stereo, but I have no idea how to do that, and Googling it hasn't helped. Are there any other solutions anyone knows about? I've seen multiple other posts about this issue, does anyone know if EA is even aware of it?? The plot, character development, and dialogue are my favourite things about Dragon Age, so not being able to hear dialogue in every cutscene takes away everything that made me want to play the game in the first place...
