Re: Dragon age inquistion low speech volume during cutscences!
You need to go into the control panel for your sound card and manually change the sound to Stereo. The game thinks you're using 5.1 speakers and is playing the voiceover on a nonexistant front center channel, so all you can hear is a faint echo in the right and left surround.
Alternatively,
This could be a problem with your headphones. TO isolate the problem, try running the game on your speakers and see if you encounter the problem. If not, then I'd suggest you try a different set of headphones or use the headphones on another product.
It could be faulty or damaged wiring (a very common problem with headphones).
If all that fails, then try configuring your Audio options in Dragon Age Inquisition, and again test other games to ensure the problem is isolated to DA: I.
