To Mr. Green, and probably anyone having problems with tinny, quiet or missing channels
With 5.1
capable sound cards like yours and my own, 5.1 outputs take the place of the ports normally used for Audio Out (green), Line In (Blue) and Mic (Red), and, seeing as the manual for these headsets doesn't come with a direct guide for people without labelled ports, after swapping around a few times and running a few tests to make sure, i found that (in my case, and hopefully your's too) that the sockets were arranged this way:
Audio Out (Green) = "Front"
Line In (Blue) = "Sub/Cen"
Mic (Red) = "Rear"
You also have to ensure that you have enabled 5.1 on your sound card in order for these headsets to work properly as i'm sure most people do, but for those that don't know how to do this, simply follow these steps:
1. Click Start and select Control Panel
2. Select The icon that has the word sounds etc on it, and select "sound and Audio Devices"
3. In the box that pops up, go to the bottom of the box and select "advanced" in the speaker settings box
4. Choose 5.1 in the "Speaker Setup" box drop down menu and then click ok, and then ok again to exit the sounds and audio devices menu.
Your sound card
should now be set up for 5.1 output, but remember that you may also need to select 5.1 audio output in any games or dvd player programs that you use for the headset to work with them, as all programs have their own independant audio settings, and probably wont automatically adjust themselves.
I hope this helps you guys who are having problems, the medusa headset is a brilliant headset, with great sound quality and they're really comfortable to wear for long periods of time, much better than the old generics 2.1 headset i had before
