[Precision 3630] [Ubuntu 18.04] No sound

Hello everybody out there!

My laboratory has just purchase a Dell Precision 3630 desktop computer for me. According to directives from CNRS, I had to encrypt my hard drives. Also, my laboratory uses the last Ubuntu LTS, being 18.04 nowadays, while the computer came with Ubuntu 16.04. Well, I must say I also do not like standard Ubuntu partitioning. Therefore, I had to reinstall the whole system.

Everything works fine, but for the sound: I cannot get any sound any more, while I did hear some sound when I first powered on the computer with installation from Dell. Therefore, I guess this is nothing but a configuration problem.

In the audio mixer, all I can see is a virtual output (as I am French, everything is in French) :audio-mixer.png

Here are some information on my system:

Well, something is wrong with Pulseaudio configuration, I guess, but I do not know what to do. Does anyone have some suggestion?

Best regards.

Hi, about to buy the very same PC and do more or less the same reinstall like you. Did you figure out the issue?
