Bill, Yeah, if you've already replaced the card once (did I 'hear' you say that?), and there's been no change, I'm betting on the mike or it's cable. Regarding headphones into the mike jack, actually headphones, speakers, and microphones are very similar electrically and in the way they operate. Mikes change physical movement (of their diaghram) into electrical impulses, and speakers/headphones change electrical impulses to physical movement. Actually, if you connect a microphone to a speaker output (like a headphone jack), and are VERRRRY careful (using VERRY low levels), you'll be able to hear the audio coming from the mike. Mikes are very delicate though, and very easy to "blow" with too much volume. Of course, impedences and such are wrong, but it works well enough for a test! Here's another idea…try the suspect mike with a known good tape recorder. Check for bad connections also, by wiggle-ing the cable, especially where it goes into the plug at the end of the cord, and also where it goes into the mike itself. Let me know! Mark Haase
