This afternoon, I bought a pair of ear plugs (the large flat kind that hook onto my ears). Plugged them in to test and they work perfectly. I'm listening to streamaudio.com as I type this. However, when I tried to watch a youtube.com video (my wife exercise dancing) just silence. She had the same video on to test and the sound was fine on her box. Then, I tried system-config-soundcard and with the volume set at 100%, just silence. Does this have to do with lower voltages coming from youtube.com and system-config-soundcard or is there some other explanation and a cure? TIA....
