Amnesia: MFP has no sound at all!!!

[assasin199127]

well, you misunderstood me. I use sound card for movies and games when friends are with me. I have HDMI for Screen not for Audio and Amnesia was working before with drivers for HDMI audio installed (while I didn't use them). I use sound card because ASUS used crappy micro chip for mobo integrated 7.1 surround sound and it either burned or something else. so the only 2 events I can remember is changing screen (I bought 27' LED screen and connected with HDMI cable for best quality) after that I didn't play game for a while but recently when I tried to, it had no sound. I tried tweaking with settings different configurations no use (I returned them to default after). so here I am...

p.s. headset is wireless
