My work colleagues have introduced me to Sonar Cakewalk music software. I think everyone knows that this software rocks.
Unfortunately Dell laptop owners (such as Latitude and Inspiron) will experience Audio Driver problems when using the Sonar software. I found that by going into Options/Audio/Advanced and setting Driver Mode to MME will solve the problem. Remember to restart the software after any changes made.
If you still don't have sound, go back to Options/Audio/General and change the Playback Timing Master from None to the Sigma Tel C-Major Audio, hit OK, and finally restart.
