Hi,
I just recently bought Starcontrol Origins (without any dlc) and when starting the game I'm immediately confronted with a voice bug.
First of all; in the intro cinematic the text and voice are out of sync with the video. Text goes faster than voice, voice is lagging behind of the video and at the end the last sentence gets cut off.
The big problem is that once I'm in the game, the voice lines get cut off too early when speaking with different characters. It's not every sentence, but at least a third of them get cut and especially if the sentence(s) is long.
I've tried testing different graphics/resolution settings, edited framerate ratios and tried to start the game again several times but the bug persists. And oddly I can't find any reports either in here or in the steam forums regarding this bug.
It seems like as if the voice lines are not synced properly with the game, either "running" too fast or the clips timeout.
I hope someone has some ideas/tricks that I can try to fix this, because I find this to be a blocker issue for playing 
EDIT:
Issue is fixed!
For whatever reason, a simple reboot of the pc fixed the issue.
Most likely something went wrong in the first time startup and I assume windows had something to do with it. Once computer was rebooted and game files were loaded again for the "first" time, all the sync issues were gone.
