When using the UAD-1 powered DSP card plug-ins as DirectX effects and SONAR's transport is looping, a "Powered Plug-Ins Error" dialog may appear, and audio may eventually become silent. if this occurs, disable looping and restart SONAR's transport in order to regain any audio signal. The UAD-1 plug-ins should work properly if looping is disabled.
