Sem áudio - Ubuntu 15.10

1

Minha placa-mãe é uma Gigabyte G1 Sniper M5 Na página de download da referida placa, mostra que eles fornecem apenas drivers para sistemas Windows.

Estou assumindo que é um problema de driver que tenho. Eu passei por toda a solução de problemas de áudio padrão e nada.

EDITAR:

Mensagem de erro para executar o gnome-control-center:

Eu só faço o ubuntu 14.04. Mas eu não encontrei nenhum problema de saída de áudio sobre as permissões dadas para / dev / snd e os arquivos lá. Nos meus sistemas, os arquivos têm permissões para o usuário raiz e grupo de áudio.

Não há permissões mundiais, portanto, um usuário deve pertencer ao grupo de áudio para ter permissão.


ls -l /dev/snd to see permissions.

.....@xen2[2145]ls -l /dev/snd

If your /dev/snd files have the same permissions 
grep audio /etc/group and see if you are in that group.  

I added my username to group audio with 
sudo usermod -a -G audio "myusername"
do not quote " your user name.

I use fvwm as a window manager and start gnome stuff in an xterm. Or Gnome-Terminial.

my quick test of sound
gnome-control-center sound see if the sound effect output. 
No then do it with sudo gnome-control-center sound and see if sound effects work. 
if it works for sudo or root and not for you then it is permissions.

I just installed 14.04 on my laptop using amd64 desktop iso on a usb.
but default it install unity.   Sound did work out of the box.
But there are not the gnome-control-center sound utility.
so I
sudo apt-get gnome   It installed lots of gnome utils .... also
it asked me to choose a window manager ligntdm or gdm.   I came with lightdm highlighted and I left it.    I will be installing xdm and then I will use it.
I suspect xdm is more generic than gdm or lightdm.
Then I ran
sudo gnome-control-center sound and under Sound Effects there was only the Default and it audio clicked as I tapped it with the mouse.
