So, as you can see in my Signature, I have a couple of other nice audio pkgs; which fortunately, are NOT having the same audio issues Sonar is having. I've noticed that Sonar has a particularly tough time keeping the Bit/Sample rates that I established for my Alesis I/O 26 (24/48). According to the Bit/Sample rate display in the lower right corner, it keeps reverting back to 16/44.1 despite verification of ALL...YES, ALL...settings that can be checked, or that I've ever checked before, which incl.: 1.) The Audio tab that configs the ASIO driver. 2.) The Audio Bit Rate under Tools 3.) The Control Pnl under my Alesis device. 4.) The Win7 Contrl Pnl under Properties for my device (Playback AND Recording). Both are set to 24/48. I've even tried setting it to 96kHz, but Sonar keeps resetting it back to 16/44. Neither Samplitude ProX, Audition 1.5, or RealBand, or BIAB2013 does this. Also, I had tried updating to X2 Studio, and was still having the problem. I'm NOT bashing Sonar, just stating facts, so please hold the negative comments. Thanks, KC
