Do me a few weeks ago a 5.1 headset jack bought. Unfortunately, I did because of my Master Slave outlet disturbing humming noises and the 5.1 was not working properly. As a solution, I have now bought USB soundcard. The result: sound card plugged in, connected headset, no humming noise and the 5.1 works. Driver Installation went with Windows 7 64bit automatically and so it was just plug and play. At this price very recommendable
