Under Win XP I could record any sound played on my PC using Adobe Audition 1.5. After I upgraded to Win 7 64-bit Prof, I keep getting this error message: "Can not find the mixer program "sndvol32 /r". I have received the same (or similar) message using other audio / video programs like Camstudio and Audacity. Is there a setting I need to change? I don't find that file on my PC. Please help.
