      title Important.
      The default microphone/speaker is defined when adding a Video capture device object. If you switch the default microphone/speaker (for example, by connecting a USB camera or microphone/speaker connector, or simply changing the system settings) after that without unloading Axxon PSIM, then switching to the new default device will NOT be performed automatically. To update the linked device, restart Axxon PSIM or delete the Video capture device and Audio card objects and re-add them.
