Mac mini and Logitech gaming headset

I take it you have already gone into System Preferences -> Sound -> Input Devices and chosen the headset as the default device for the mic ?

The line should be the mic option assuming you have a line in and a line out connection on the back of the Mini and the sound out and mic in connectors are plugged in to the right connections.

I have a USB camera with built in mic ( Playstation Eye ) connected to one of the USB ports which I use for the mic and it shows up below line in in the settings so I don't use the line in unfortunately.

The line in is meant to be the mic input. I have a late 2009 Mini and it has a line in and a line out as in the picture in the link below. Is yours the same ?

Having looked at the specs on that page again it seems as if the line in may not support mics after all. The other option would be to get a USB adapter with a female line in and line out and connect the headset to one of the USB ports as this should work. I've done just that on my MacBook Air which is running 10.6.3.

The Playstation Eye on my Mini is connected the same way. If you can't find an adapter for your existing headset then you might need to consider buying a new one that does have USB as an option.
