the list of audio input and output devices, including one or more Osprey cards. When you have chosen
the device, click OK, and you will be returned to the Recording Control display (Figure 71).
The Osprey device is not a mixer in that it does not allow for mixing the various audio sources.
Therefore, when you select one audio input, any other input you previously selected becomes
unselected. The Select check box at the bottom of each source sets which source is actually being used.
Osprey cards have hardware gain control. To control hardware gain, use the volume slider in the mixer
applet. The unity gain setting is when the volume slider is all the way up (in default driver settings).
The quick-access volume control (left click on the speaker symbol) on the task bar controls recording
volume and playback volume. To change record levels, go to Options  Properties  Recording.
