Sound Problem with BOSE Companion 5.

[ikkithehunter]

I have a PC version of Bioshock, and X360 Version of Bioshock 2.
There is a problem with Bioshock 1.
I'm using BOSE C5 speaker system, also using Windows7.
I cannot hear any sound in game.
There is a solution for Windows7 user who has same probelm.
but this solution doesn't work for me.
because my sound and speaker system is BOSE C5.
Is there any way i can play Bioshock with no sound problem?
