I have tried with arecord test.wav and still no result. Testing it in windows all works normally

Solution

I do not know about Ubunbtu-Studio.
But I do for Audacity:

Set Audacity to use Pulse



in edit | preferences:

Then you need to correct your Pulse settings:

1. launch some music on your computer
2. start a recording on Audacity
3. open Pulse
   
   
4. go in 2^nd tab (recording) make sure that Alsa plugin is capturing: Monitor of Audio interne Stereo analogique (or something like that depending on your language)
   
   

and now you can record:

Thank you Boris. I have followed your instructions and all works well when I want to register sound from any other application. The problem with microphone not working still remains. No sound input in audacity or any other application that uses a microphone

[Boris]

@LucianMarian I suggest you to mark this answer as accepted. And create a different question for your micro problem.

[Boris]

@LucianMarian for the micro problem, I suggest you to include in your question pictures of your pulse settings, it could be the source of the problem.
