[. . . ] Configuring the for Driver version: 5. 00. 2000 Build 112 ControlPanel version: 1. 03. 25 Build 112 Sonar version: Date: 1. 0 Aug. [. . . ] Sonar uses the hardware's standard WDM driver support and achieves, thanks to the kernel streaming, a latency comparable to ASIO. Start with the setting "DMA Buffer Transfer Latency" in the Settings menu of the EWS88 (EWX 24/96) ControlPanel (a secure start value is 10 ms for example). When more than one card is installed in a cascaded system the settings must be made for each card individually (always with the same value). With the first starting of Sonar automatically the "Wave Profiler" will also be started to carry out the audio hardware test. If this does not happen automatically, then you can start it manually in the menu Options \ Audio Options -> Wave Profiler. 2 SonarTM After the hardware analysis you have to select the input and output devices in the menu Options \ Audio Options -> Drivers. Optimizing: To optimize the latency we recommend the following configuration steps: 1. In the EWS 88 (EWX 24/96) ControlPanel you can set a shorter DMA Buffer Latency time. Pay attention that on cascaded systems with more than one card each card is set configured separately. [. . . ] If you hear clicking, drop-outs or if the sound completely cuts out when using Sonar then set the changed values from points 2 and 3 back to their original values and/or adjust them in smaller steps to determine the correct settings for your PC. Important: After making any changes to the parameters described above the Wave Profiler must be started again and the selection of the in and output devices must be controlled in the menu Options \ Audio Options -> Drivers. 4 SonarTM [. . . ]
