So if you want to spend your money on that garbage, be my guest. I'll just be happy that I was of help to other people who weren't so reckless with their choices of PC game entertainment.
I bought the game during it's weekend sale on Steam, beat it twice and all the DLC once. I did not have the sound problem you're describing at any point.
I had the left channel surround sound problem, which I "fixed" by switching to two channel and my headset, along with a couple bugs here and there (worst being the game not transitioning to a cut scene properly, leaving me running around the end of Shaak Ti's level confused until I reloaded to a checkpoint), and being firmly annoyed by the 30 FPS cap.
I'm sorry you got stuck with that sound problem, I really am, but the attitude you're bringing into this thread is a little much. It's a terrible port (really, just saying it was done by Aspyr gives THAT one away) but for this price there's no need to rage on people for wanting to play it regardless.
It also probably hasn't been mentioned, but stay far away from TFU unless you have a 360 controller. Aspyr did the smallest amount of work possible and didn't even add the option to rebind keys in game and stuck it on the loader. In addition, the default controls are awful and when you *do* change the keys they don't update to the new ones for the QTEs. There's also a specific section of the game that's significantly harder with KB/M. It's reeeeally bad.
360 controller works perfectly though.
