Hi all - If I can't resolve my headphone problem, I was wondering if getting an external sound card would do the trick, I've found one on Amazon that says: USB 5.1 Stereo Sound Card Adaptor - Windows 7 Compatible by SFH Distribution Technical Details a.. Virtual 5.1 USB sound card b.. Line out for speakers / headphones - Line in for microphone c.. No existing sound card required. This sound card works completely independently d.. No additional power required - Completely powered by the USB port e.. Compatible with Windows 98SE, ME, 2000, XP, Vista and Windows 7 I'm wondering how this would work in tandem with my onboard sound card, could I some how keep the onboard card for when I'm listening via the built-in speakers, and just plug the external card in when I want to use headphones? If so, tips on what I'll need to do to have both cards available, and how to switch between them would be much appreciated. Thanks - Andy
