Out of curiosity, which of the sound mods are you using. I was looking into using one of the available but I would prefer to avoid these problems.

This happens to me using windows 7 and a surround sound. When looking straight at a voiceover, its sound should be output to the front speaker but it does not. In order to hear something the speaking character should remain in the right or left corner of the screen so that the left and right speakers are used.

Hardware: Xonar D2X, 5.1 surround system.
OS: Windows 7 64 bit.

This seems related to Issue 0010145.

This issue is fixed in my case with the latest dev build (12/11/2013) and using a dedicated sound card (Xonar D2X) with surround speakers. Thanks for fixing this.

This is also happening in my case. Playing the campaign on a windows 7 OS with xonar d2x and 5.1 speakers (logitech z5500). The voiceovers cannot be heard from the front speaker. No mods are being used.
