So basically I have a very old PC with an onboard-soundcard.
After installing xubuntu 18.04 the sound had worked perfectly fine. Now after I've had to reinstall xubuntu, the sound stopped working (it told me that some parts of the operating system might not have been installed properly)
All I see is described in this article. Just a dummy output channel.
I've tried the first two methods. All that it is showing me is
Unloading ALSA sound driver modules: (none loaded).
Loading ALSA sound driver modules: (none to reload).
Then I've tried the third method, but "RUN=no" was already there by deafult.
What else can I try? Also, I am not an expert, so please write an answer that is easy-to-follow.
