From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I don't know if I didn't install non free firmware. Pavucontrol is installed. If I type alsa on a terminal it returns: bash: alsa: command not found.

ETA: turns out I only had to update the system

There isn't an alsa command on my system either, so that's no surprise. But we'll need more information to track down the cause, such as:

What (sound) hardware are you using? (try lspci | grep Audio)
What happens when you try to play a sound? Does it get stuck loading / at 0:00, show an error, or just play silently?
Is your system using pulseaudio directly, or via pipewire? (try pactl info)
What shows up in pavucontrol? (Is it detecting your speaker, or just "dummy output"? Is sound muted, and can you unmute?) Try also alsamixer.
If you installed non-free firmware, you should have a few lines like deb http://deb.debian.org/debian/ bookworm main contrib non-free-firmware in the file /etc/apt/sources.list. If non-free-firmware is not present, then obviously you have no non-free firmware.
