I still get a reverb trying it that way too. Here's what's happening. I plug a phone into the, "line in" jack (Blue) jack. I hook a CD player into the, "front mic" jack on the front of my tower. I call my phone number. While the CD is playing, I also talk into my cell phone which is connected to my home phone which is connected into the, "line in" jack. I say something and it comes across on the stream. About 10-12 seconds later, the same thing I said comes across on the stream again, only the quality is much less, like an echo of what I just said. On the recording tab, I have selected, "stereo mix" as the default communication device. That's the only thing that is checked. All of the inputs, the, "listen to this device" is unticked.
