Removable (USB) Sound CardsControls: Edit Menu >> Start Preferences >> Device Changing device numbers is a particular problem with USB sound cards. In a typical situation you may have a single internal sound card, but occasionally want to use a USB sound card. The internal card is Device 0 when only it is present, but the USB card becomes Device 0 as soon as it is plugged in, and the internal card becomes Device 1. To handle all possibilities, you could have three different icons, as described under Managing Multiple Devices: The default icon with no parameters would be used when the USB card is not present. When the USB card is plugged in, you'd click another icon to tell Daqarta to use that device, with DaqartaU (for example) as the base filename. The Target command line under the Shortcut tab would be: "C:\Program Files\Daqarta\Daqarta.exe" O:0 I:0 N:U When the USB card is plugged in, but you want Daqarta to ignore it and use the original internal device, the Target command line would be: "C:\Program Files\Daqarta\Daqarta.exe" O:1 I:1 N:0 Note that here N:0 tells Daqarta to use the same Daqarta0 files that are used in the default situation, while O:1 and I:1 indicate that the internal device has been renumbered by Windows. You can change the icon appearance to have a transparent background instead of a black starfield. This can help to tell different Daqarta installations apart at a glance.
