Problems with Audio Recording

[wonder]

So you have Line In and a Line Out as seperate jacks ?

Yes, I have Line In and Line Out separate jacks.

Like I said. If you can record the sound then you can also listen to it. You just need to find the switch to unmute that Line In or turn up its volume.
As the sound card is supported fully it should be only a configuration setting you need to find.

I think (its my think ) that not, because, in linux, I can record the sound but only by mic jack (rear or front mic) not by Line In.
For this reasson, I can hear that I recording, I can hear my external player, because are by line mic not by line in. Like are by line mic tt is not logical to hear what is being "spoken" by microphone.
In the config, only appears for select:
In line
Rear Mic
Front Mic

In windows, appears also Line In.

This is the difference.

Maybe it's a configuration problem, but I'm starting to go crazy, it's a few hours / days and I'm not able to find out what the problem is.

This is my alsamixer:


Not view any problem and how configure for Line In...my external player I need connect by Line In, not by Mic Line...
