Check your in game microphone settings: Options>Preferences>Game Sounds. You should have your onboard sound device there. Notice that Realtek which is the most common one has both a HighDefinition and Digital in- and outputs. The former is what you should choose.
In Options>Preferences>Voice set the Microphone slider at full to enable the boost slider.
This was it. It had realtek selected. But it had set it on digital for some reason.
Thank you
I have most of my house set up for ethernet. the only things that do wireless are tablets and phones and two TVs.
On another note.
Every time I log in I get the message
"Not receiving updates. switched to TCP"
Im using Fios with a brand new router (but this was happening even before)
Any suggestions/reasons why?
