For the last 2 hours or so, I have been cursing at youtube for having some adverts pop up operating in the background or some site I went to. Producing a noise that sounds exactly like being at the ocean with the waves coming in and crashing on the shore. I mean the sound was so perfectly reproduced there was no question that it was a sound wave being played in the background in loop.
A nice pleasant sound btw, low in the background etc.. I decided it was time to rid it.. I looked around and could not find anything on the PC running producing it however, my Ham rig is on at the moment and I have the audio out connected to the MIC input of the PC isolated with a audio 1:1 transformer for Slow Scan tv.
Apparently, a poor connection in the Jack+Plug of the MIC port in the front must of been causing some diode connection along with the transformer being inline and due to the fact that the MIC input does have a small DC on it to power up microphones.
A phenomena you could hardly ever produce if one tried in a 100 years.
