You can adjust mic settings directly from the browser (in Flash Settings).
To turn on / adjust microphone:
1. In the Vyew application, right click somewhere on the page and select “SETTINGS..." .
2. Select the MICROPHONE ICON tab which is 4th tab from the left.
3. When you speak into your mic you should see the record volume bar jump.
If you dont, then select a different microphone device from the drop down list
until you see a green/yellow volume bar jump up and down as you talk into the mic.
Now when you press the “Push-To-Talk” button in Vyew, you should be see a red
volume line jump side to side as you talk, which lets you know you are broadcasting.
