Problem: Repetitious Sound.
Possible Cause: An IRQ resource conflict with the USB controller and another device (PC only). Often this will result in a small segment of sound (0.5 to 1 second) repeating itself over and over, sometimes completely locking up the computer. See the general troubleshooting suggestions at the beginning of this section.
•Problem: I’m getting some pops and clicks in my audio recording.
•Possible Cause 1: Input levels are too “hot,” causing clipping or input distortion. Make sure you have the proper signal levels coming from your source audio device, and lower the output if necessary.The incoming levels may be easily viewed from the Audiophile USB Control Panel peak meters.
•Possible Cause 2: Your application software may not have the proper audio buffer sizes set. Each software application handles this differently, but typically there is somewhere in the software’s setup to set the size of the playback and recording buffers used by the application. Some applications also require you to run a calibration (sometimes called “profiling”) the first time you use the software with a new audio interface. For instance, if the clicks are present when using Cakewalk SONAR, then try to run SONAR's Wave Profiler.
•Possible Cause 3: Some accelerated graphics cards use excessive amounts of system bandwidth, preventing the recording buffer of an audio interface from keeping up with demand. This can cause clicks in the recording. Reducing or turning off the graphics card’s graphics acceleration feature often resolves this problem. In Windows, the level of graphics acceleration is accessed from Start Settings Control Panel System Performance Graphics.
Problem: My software application keeps telling me “sample rate not supported” or some similar message.
Possible Cause: This would most likely occur if you were trying to select 96000Hz as a sample rate, and the Maximum Sample Rate available from the Audiophile USB Control Panel is 48000. Open the control panel, and uncheck the Active Port boxes until you have only one port selected for either input or output.
