Alright, I have a M-Audio Audiophile 2496 and am runing Sonar 4. I can get audio fine playing a CD, etc. but can't get any sound from Sonar. I have tried various driver setups and configurations (ASIO, WDM) and still get no sound. Soooo frustrating! I think I have tried every combination possible, please help!
I don't use the same gear as you, but I did run in to the same problem. What I had to do is uninstall everything, all software and soundcard, then install the soundcard, then install the software. Also, if you get it working right, set up a restore point on you computer in case things go haywire again. Hope that helps.
