I attempted to update the 44VSL driver to the latest version. I tried uninstalling the old driver per instructions in the Presonus KB and then reinstalling using the installer, and also tried by just running the installer by itself.
Each time 4 drivers showed up in both the playback and record options in Sonar:
*AudioBox ASIO Driver Mic/Inst 1
*AudioBox ASIO Driver Mic/Line 3
AudioBox VSL ASIO Driver Mic/Inst 1
AudioBox VSL ASIO Driver Mic/Line 3
The ones with the * were selected by default. The other ones were the old drivers designation. I even tried deleting the AUD.ini file to see if that would get rid of the olrder driver designations and it did not. I am pretty certain I removed the old drivers first, but I had to revert back to them as I was getting the "rice krispies" (snap-crackle-pops) where before I did not.
Have any other Sonar users experienced any issues with the Audiobox drive update?
