I don't know if this may be the problem, since I do have audio into and back out of the usb device, but I'm a bit confused about the wiring at http://usbradio.org/usbfob.pdf for the resistors. The written instructions say that the end of the resistors that are twisted together get connected to the white wire and that the loose end of 68k goes to ground and the loose end of 470k to pin 3 (I'm guessing to RX Audio from radio) The picture shows the white wire (black in the picture) is connected to the loose end of the 470k while the loose end of 68k is connected to ground and the twisted end to pin 3. I don't know if this has been talked about before, I gave up searching through the archived manually. It would be a lot easier if this were on a forum so that you could just search the forum for keywords. Any help on which one of these would be right would be greatly appreciated.

I know I have audio going into the device. When I made the modifications to the usb device, I decided not to remove the audio output jack so that I may use it for testing purposes. So I plugged some speakers in, went into alsamixer, un-muted the microphone, turned it up a little, and I had sound from the radio without any problems. So why can't asterisk hear the sound when tuning? Have I forgotten to do something else before trying this?
