    I host a server and some participants complain about static noise coming to their headsets. Let me know anything they can do to get rid of static noise.

    1) They might be having too much Overall Delay, causing static.
    2) Mute each other participant until the static goes away, then the last person muted is the source of the static.

    Hi Emi,
    The static noise is not coming from your server.
    The noise can be coming from the communication (Ethernet) to the server or from client hardware.
    Jonathan's point 2) is the way to find where to look further. (note that if the noise is always there no matter who you mute then the noises are coming from your own client setup :) )
    Once you have found where the noise is coming from that client can try using other buffering or audio quality to find a combination that works better.

      Hi Don,

      Thanks for your comments below.

      Since I am not a tech person, would you expand on “other buffering or audio quality”. It seems I am the source of the noise. Does “audio quality” mean I should use a sound card to improve the quality or eliminate noise? As for buffering I set (on the setting panel) buffer delay 256. Should I do anything on Jitter Buffer?

      Best,
      Emi

        Hi Emi,
        open the "Settings" window. On the left at the bottom you will see all the buffering options. Try them all with and without "Enable Small Network Buffers" set. The Jitter Buffer in the middle of the window you can leave Auto, although sometimes turning "Auto" off and setting the sliders somewhat higher can improve things. On the right of the Settings window are "Audio Channels" and "Audio Quality". Try setting the Audio Channels to "Mono" and Audio Quality to "Low" and see if that makes a difference.
        Try all the combinations, you can't break anything.
        If you are able to find a combination that works OK for you you are in luck.
        In any case using an external audio box will give you better sound quality and lower delay than when using your computers internal hardware.
