The laptop is sitting in a docking bay on the same table as the desktop, but is not connected to the stereo. It is the desktop that serves as the audio source. The desktop has no microphone, although the sound card does have an input jack for one. There is a microphone on the laptop, but I don't see how it could have anything to do with the problem. Also, it is only a little hole less than half a centimeter. When the wailing started a few minutes ago I put my finger over it and there was no effect on the feedback. As for the desktop, not only does it not have a microphone, but I have turned off all microphone inputs in the alsa sound thingy. Those that I couldn't put a red X on I moved the sliders down to zero. > Or perhaps it is the radio eavesdropping device implanted in your > house by FBI agents back during the J.

It would even be difficult to diagnose if you were standing in the room. Because every slight movement of your body affects it. The fact that body movement changes the frequency and volume tells me it has to be RF. Does there exist a device for sniffing out the source of whatever is transmitting RF? Maybe I could point the thing at all the electronic equipment in the room until it lights up. I'm mostly pissed off that my fancy triple shielded audio cables that I paid $5 for on eBay actually made the problem worse. The signal has to be coming into the receiver via that cable, because it is the only cable connected to any of the input sources on the receiver. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
