Alright so yeah blah blah Bliz doesn't own ventrillo blah blah blah.

But I don't want to go to vent forums to make an account.

Anywho.

Last night everything was working perfectly. Until my brother got on after I went to bed. Now people hear what I hear on vent and I shouldn't be having this problem unless somebody installed a new sound driver or a new sound card altogether.

Now how to I fix this problem?

Hi Poison,

Making sure that your sound input setting is set to Microphone instead of things like What U Hear or WAV would be the first thing. Windows has this option, and so does Vent. We only have the instructions for Windows so you're stuck with Vent's settings if this doesn't work.

You'll want to try and edit Ventrilo's options. They should be under the Setup button, for Input device.
