If you have a non-amplified microphone plugged into a blue colored jack on a Sound Blaster sound card (e.g. Live!, Audigy), I'd love to hear about it. I have a Live! 24-bit that has a blue colored (doubles as line in/mic) and have tried everything I can think of to get it to work. My mic works very well on my on-board sound card and other sound cards that have a dedicated mic jack. I am all but convinced that a standard mic will not work on these low end SB cards. I'm hoping someone here will prove me wrong.
The cost difference between the cheapo SB's (all have the blue mic jack) and the ones that are split out (pink=mic, blue=line in) e.g. Audigy 4 is about double.
Thanks for anyone who can shine a light on this issue.
