From Character Creation clear to final mentor mission all the Comic Cutscenes play their music and sound effects but the voice overs are not working at all. Only in the 1st part of Character Creation just before picking a gender will the only VO I've heard play. I've ran a file check, I've even uninstalled, cleared the left over folders and then reinstalled. After a total shut down and reboot.
How are your ingame audio settings? Which language version? Do you have any interfering audio programs? Skype, audio driver filters, recording software...
