I have had this same problem. The short story is, don't use the Creative driver for the USB Xi-fi. Use Windows' built-in "USB Sound Device" driver instead.
I have a hypothesis, but someone with more RAT programming experience would be able to say if this is plausible: It seems that the Creative driver [for the USB Xi-fi] separates the input and output mixers into separate devices. Since these individual mixer devices are not 'full duplex', the AG software no longer considers them a valid sound device selection. I spent some time editing the driver's device setup to see if I could merge the devices, but never could get AG to work with the driver. -Nikkos Svoboda LSU Department of Mathematics On 4/11/2011 12:39 AM, Mike Lake wrote: > Hi all > > I am not able to detect the Audio Device under RAT/Options/Audio. > Hence we have no sound.
