The front > microphone, BTW, keeps listening. I've had trouble on my old laptop where if I use a mono adapter I don't get anything. My radioshack mic has a mono-ish plug. Apparently my old laptop wanted a stereo 1/8" plug. But a pair of stereo headphones makes a fair mono mic (left ear only). At least a good pair of over the ear headphones, I've never managed to get much of a signal out of in ear headphones. Hmmm. I just tested my theory on my new laptop(compaq presario) and it can record from a mono plug. I could swear it didn't on my old laptop(sony vaio). I no longer have that machine to test that theory with. Or it could also be the need to enable mic boost for a non pre-amplified signal. In addition to mic + gain mixer settings.
