Thanks for answering. I am not able to  answer all your questions, I'll
try my best.

No. I just play sound from CD (or DVD) or from the HD if I have ripped a
 record. I listen to internet streams too (radio).

I did not install any driver, the sound card was working out of the box
after install.

How can check this point? And, if necessary, where can I find the good
driver?

As I told: CD, DVD, HD, streams

This, I don't understand/know. pulseaudio is working. I am a member of
pulse-rt group.

I don't understand how to configure anything with this: I can only
modify a level, but how can I know what is the good level?

I don't understand this question!

Thanks for helping.
