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. Ifnon-free-firmware
is not present, then obviously you have no non-free firmware.
- What (sound) hardware are you using? (try
In such cases on Debian, as root, I try my "lazy" approach
apt install vlc mplayer vorbis-tools ffmpeg mpv
which may pull in the needed codecs to play mp3, ogg and flac files. Does playing a video in your browser work btw ?
