Welcome to Seven Forums Matt123321. Easiest is right click the speaker icon in the system tray and click on Open volume mixer
> Make sure the mic isn't muted.
If it isn't, try some troubleshooting: Right click
the speaker icon in the system tray> Click Recording devices
> Does it show the microphone with a green check mark and default device?
If not, highlight microphone> Click on Properties
> Does the Jack information
show the location you are plugged into (IE: you have it plugged into front, does it list rear panel, etc.)
If the mic is detected and default, highlight it and click on Configure
> Click on Set up microphone
> Click on type of microphone (headset?), and click on next> Follow the wizard
If needed, post some screenshots of the sound screens. I don't use a headset myself, but I'm sure many who do can help if my suggestions don't. Screenshots and Files - Upload and Post in Seven Forums
