Hello, I was about to make a thread for this topic and here it was....I cannot get the simple OpenAL to work for the life of me! I am getting great Dolby Surround as my ASUS Xonar soundcard has a headphone amp...but forcing OpenAL via the darkmod.cfg file crashes the game with the "hardware buffer" error! Don't know why it's not working, I tried re-installing drivers and OpenAL...it was working gr8 for me before in Doom 3 but I recent upgraded my PC and re-formatted the HDD, and that might have screwed something up! I believe it doesn't work in Doom 3 either for me now. I guess even turning it on will not make much of difference as it will only probably give the Dolby effect that I already am getting.....But OMG! If we can get sound via EFX or some other alternative like in the EAX video posted above, the immersion factor of TDM will be increased tenfold!
