Can you try either another mic/earphone in the laptop, or the existing mic/earphone in a different machine? It could just be the mic is broken. Also, some mics on some earphones have a tiny on/off switch.

I have tried a number of other headphones and have the same problem.

[Bit of Googling later] Also no capture. Well it's listed but it may as well be on mute. These are new headphones that work with my tablet, by the way. I'm assuming capture and input are closely related.

In the event there are some who are not tired of this now, here's what amixer gives. Are there any clues here?
