I noticed that some games won't even start, and some that do will have ZERO audio and you can not switch the audio once the game is going. In such games I have found something that works almost 100 percent of the time. What I do is I set the Nu-Audio control panel to 32 bit 96000 and hit apply and leave that window up on the screen. Then I start the game, the game loads with sound, and once I can hear music or sounds and I'm in the menu to the game I will hit control+escape (or whatever method you can) to get back to the desktop where there I select the Nu-Audio control panel and then set the audio to 32 bit 384000 and then go back to my game............PRESTO!!!!
I don't know why this works, or if it is truly working, but according to the Windows sound icon it is reporting 32 bit 384K audio, so think of this as being to audio what "upconverting" is to video. It would obviously not sound as good as something truly recorded at 32 bit 384K (and almost nothing is ATM and true 384k samples would demand serious cpu bandwidth to already over taxed cpu's while gaming) but it does sound more warm, livelier, and more appealing to the ears as the D/A (digital to audio) convertors are rendering 384,000 slices of stereo 32 bit audio PER SECOND which gives the illusion that the sound is closer to reality....and thus...."Lifelike audio".
But it seems the newer games like Battlefield V and Battlefront 2 are not allowing over 192K sample rate with this current driver (1.0.3) without distortion (buffer?).
