I had a problem with Camtasia recorder sound not working. But i found out the reason:

The box (red arrow) that is to be checked with a microphone icon above and "Microphone" text next to is to be checked. I thought this was if you were to USE MIC, but it seems you need to check that to record sound (in my case using a headset). And a way to know you will be able to record sound is to look at the bar (Blue arrow), it senses sound (mouseclick if turned on, music and so on).

 

Hope it helps for those with same problem!

Use 'Manual Input Select' and select 'Stereo Mix'

 

Go through and make sure that 'Stereo Mix' is selected for everything. I found that 'Speakers' only worked when I was actually using speakers, and not front-jack headphones.

Coud you give a very precise direction instructions as to the thing you said? (Just so that i am sure i did exactly what you told me to do)

EDIT:

Here's what i did, i picked "Headphones" at Controll panel, and i choose "Stereo mix" in Camtasia recorder. But it went back to "Line volume". So when i click audio options, pick Stereo, after i click OK it goes back to "Line Volume".
