I suggest that you run "alsamixer -V capture" so that you only see the
recording controls.  You may need to use a switch, rather than a sliding
control, to boost the recording volume.  For example, there may be a
switch to change the input from line-in to microphone mode.

I'm going to close this bug because the original problem is fixed.

Once a job is fouled up, anything done to improve it makes it worse.

Thanks for the suggestion but as I say no new channel appear so the capture section is empty (by the exception of digital channel).

The original problem was the lack of the channels and that is not fixed. The only difference is that I can now record with digital but I still need capture channel (or other one) to increase the volume.
I record with digital on .26 and only by increasing capture volume I can hear well.

If you believe that I must open a new thread to solve that issue I'll do that. But I think the problem is the same.

Thanks
