Audio recording control comes up with wrong
device and wrong inputs
The cause of this problem may be that you currently have or have had previously, a Video for
Windows audio capture driver installed in the system. The Osprey AVStream install process normally
removes a previous Video for Windows driver, but if you have multiple Osprey cards installed you do
have the option of running the Video for Windows driver on some cards and the AVStream driver on
others. Unfortunately the Recording Control does not work smoothly in this situation. The Video for
Windows device will always try to act like it is the selected device even if it is not. You have to
manually enter Recording Control’s Options  Properties dialog to select your device.
If you no longer have a need for the Video for Windows driver, you can uninstall it using instructions
obtainable from Osprey technical support. If you are comfortable using RegEdit to edit your registry,
you can instead go to the following location:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32
