I am using an ASUS Xense audio card with the included Sennheiser headphones, after the latest patch, I cannot hear any sounds at all. It did this during the BETA and it was due to multichannel sound. I am going to try switching from 8 channels to 2 channels and see if it fixes the issues. I think the same BETA problem has resurfaced.
**EDIT** Within game I keep getting a FMOD Sound Engine Error...... any command to restart or reinitialize it??
