issue with alsa-mixer

whenever i try to use alsa mixer, i get this weird output.

ALSA lib confmisc.c:855:(parse_card) cannot find card '0'
ALSA lib conf.c:5178:(_snd_config_evaluate) function snd_func_card_inum returned error: No such file or directory
ALSA lib confmisc.c:422:(snd_func_concat) error evaluating strings
ALSA lib conf.c:5178:(_snd_config_evaluate) function snd_func_concat returned error: No such file or directory
ALSA lib confmisc.c:1334:(snd_func_refer) error evaluating name
ALSA lib conf.c:5178:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory
ALSA lib conf.c:5701:(snd_config_expand) Evaluate error: No such file or directory
ALSA lib control.c:1528:(snd_ctl_open_noupdate) Invalid CTL default
cannot open mixer: No such file or directory

i used

sudo pacman -S alsa-utils

and do have a sound card recognized by my system, however every time i enter the

alsamixer

command, i always get that weird output.

Re: issue with alsa-mixer

Does the mixer actually show bars for sound levels? What kind of sound card? Try lspci|grep snd.

Re: issue with alsa-mixer

Is this a USB device? It can often be normal that they do not expose an explicit HW mixing interface. If you wanted a volume for that you'd either have to opt for pulseaudio/pipewire or a softvol ALSA config: https://wiki.archlinux.org/title/Advanc … und_Volume

FWIW for other identifying info

aplay -lL
sudo dmesg | grep -iE 'snd|sof'

would help

Re: issue with alsa-mixer

it's a lowercase "L" not an uppercase -I but the fact you get so little from the uppercase L points to there not being a detected sound card in general.

What's your output for

lspci -k
sudo dmesg | grep -iE 'snd|sof

and in doubt install sof-firmware
