Ontem instalei o debian wheezy em uma máquina aqui, porém não tem som.
Ao ligar o computador, durante o boot já aparece a mensagem:
Já revirei o google, mas a maioria das soluções que postaram não funcionou.
amixer: mixer hw:0 load error: invalid argument
Vejam a saída do comando "/etc/init.d/alsa-utils restart"
Alguém tem alguma ideia do que fazer?
# /etc/init.d/alsa-utils restart
[FAIL] Shutting down ALSA...warning: 'alsactl store' failed with error message 'alsactl: get_control:250: Cannot read control info '2,0,0,Front Playback Volume,0': Invalid argument'...failed.

A saída do comando lspci é a seguinte:
Abs!

EDIT:
Resolvi usando a dica do colega, abaixo:
This is a known issue with the ALC887 sound codec.
See the following bugreport for details:
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/669092
Please run the following command in a Terminal:
gksudo gedit /etc/modprobe.d/alsa-base.conf
REMOVE the following single line using the gedit editor , IF it was previously added:
options snd-hda-intel model=auto
ADD the following single line using the gedit editor:
options snd-hda-intel model=generic
SAVE the change to /etc/modprobe.d/alsa-base.conf
Then REBOOT and retest sound using headphones and speakers.
After rebooting, make sure all channels are UNMUTED and volume set to 100% in alsamixer and gnome-alsamixer
Ou seja:
vim /etc/modprobe.d/alsa-base.conf
E adicionando a linha:
options snd-hda-intel model=generic
Obrigado!
