I will admit I haven't played with this lately that was a problem as of a few 
months ago. Specifically using multiple sound devices with speech recognition 
(or any other app requiring audio input such as a telephone.

For some reason, Lennox audio systems don't seem to cope very well with a USB 
microphone  because instead of letting it stand as a second device, it seems to 
displace the primary audio device in favor of a USB device and not leave the 
application which one it wants to use. My favorite use case is using a headset 
to speak with someone (voip) while running rhythm box playing some tunes in the 
background. For voip, you can also substitute wine running NaturallySpeaking.

in any case, I think is a generic problem dealing with multiple devices and if 
you can fix it, that would be fantastic.
