My mic isn't working inn TF2 have sound but no mic. its a Stealth 700 if anyone can help me with this issue let me know.
Make sure there isn't a mute button enabled on the headset. Type "control panel" in the start menu search box. Click the Control Panel result. Click the Sound icon in the Control Panel window. Click the Recording tab in the Sound window. Find and select the microphone for your headset. Click "Set Default". Select your microphone and click Properties. Check Custom and Levels tabs for appropriate settings. (I need AGC checked on the Custom tab for my mic). I usually run the Voice Recorder app to see if it is working.
