I am very sorry, but I am a true newbie in Linux.
I installed Fedora, started following tutorials that I found on the internet and I only managed to hear fog. I reinstalled Fedora and the rest you already know, I found it by chance moving bars in ALSA Mixer. Even so, today the sound has been deactivated when I open the settings and I had to fiddle with the ALSA Mixer again until it came back. When I reboot, the sound card that only has a bar appears by default. I’ve read something about changing the default card in the ALSA Mixer configuration file, but I have no idea how and I’m afraid of messing something up… That’s how I am…
