Cannot record piano

[Ionică Bizău]

I have a piano and a laptop. I use a jack - jack cable to send sounds from piano to my laptop. I can hear the piano sounds in my laptop without problems, but I cannot record them. The laptop internal microphone is recorded instead.

What can I do to solve the problem?

More information would be helpful. Which program are you using to record
your piano? Is it recording directly from alsa? or by using pulseaudio? (I
would guess the second as your info says pulse audio is running... but,
just checking) On your panel there is probably a sound icon that has
"Sound Settings" at the bottom. Selecting that should give you
pavucontrol, the pulseaudio volume control. The Input Devices tab should
show what input is being used and allow you to select between mic and line
input. You would want Line Input. There is a meter bar there too that
should show your audio in when you play. If you have switched anything you
may have to restart your recording application (audacity works well by
the way) to get the new settings. The recording tab should show the
application you are recording with when in record mode (record plus pause
is useful to set levels with before starting to record).

I am not using the same desktop as you are so my idea of how things look
to you may not be exact.

I use Audacity (http://audacity.sourceforge.net/)

I guess that by using pulseaudio. How can I record directly from alsa?

The default microphone takes sounds from room (it's the internal laptop microphone). When I select the other options no sounds are captured...

1x combo audio jack

is the icon near the jack look like a headset or
  headphone / Mic icons ?

you need line in for recording from piano 's line out

@Raymond I forgot to tell you that I use a splitter to split the COMBO jack in two: line in (the one the comes from piano) and line out (headphones).

The icon represents a microphone.

The sounds come in laptop because I can hear them. Is the problem somewhere in driver?
