    Cool GNOME ALSA Mixer Mic Not Working

    Hi, I'm trying to stream my microphone in real-time.
    I have a Logitech C300 Webcam which I'm using as my microphone, the mic is built-in and shows up as "Webcam C300 Mono" in hardware when in Sound Preferences.
    When I untick the "Mic" tab in the program, the only thing I hear is a constant white noise.
    I am trying to stream my mic through the speakers so that I can make 'Let's Play' videos, without recording 2 seperate tracks as this causes desync.
    In the past, I have tried VLC, Mplayer, Aplay all to no avail (lag)
    I have also tried RTP streaming with VLC (using the address rtp://234.5.5.5:1234), but there is STILL 1-2 second lag.
    I have also tried to get this to work using Pavu control, but nothing happened.

    Furthermore, I tried to use JACK as an alternative, but when I try to start it, it says:
