I installed debian (gnome) and i can't get my sound working. When i use inxi -A i get the following result:

Audio:     Card-1: Advanced Micro Devices [AMD] nee ATI Cayman/Antilles HDMI Audio [Radeon HD 6900 Series] driver: snd_hda_intel
           Card-2: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) driver: snd_hda_intel
           Sound: Advanced Linux Sound Architecture ver: 1.0.24

My feeling tells me my sound output is on the HDMI instead of my jackplug on my motherboard.

How can i change this to my motherboard sound output?


You probably are using pulseaudio. Launch pavucontrol (from package of the same name) to see if pulseaudio is correctly configured:

  • in the 5th tab (Configuration) look at the status of the several device you have. Their you will be able to configure your hdmi device
  • in the third tab (Output device) you can then click on the green icon with check sign to set the default pulseaudio output.

For application not speaking pulseaudio, you can create a $HOME/.asoundrc file with

pcm.!default {
     type pulse

ctl.!default {
     type pulse
  • Thanks for the reply, meanwhile with the help of some friends i got it tow work. Only 1 problem left now. Flashplugin doesn't give sound. (for example youtube when not using html5 or the settlers online browser game) when i look in pavucontrol, it wont appear, tho the other browserstreams will. Any ideas? Jun 28 '13 at 14:55
  • I belive the problem is that flash speak only to alsa. See my edit for a full answer.

  • Nope tried that already, the stream doesnt show up. Others i get from iceweasel do (for example youtube video on html5 instead of flash). But well, i guess i need to get a 5.1 soundcard anyway, i miss my surroundsound (new motherboard seemed to have only stereo out) Thanks for the help anyway Jun 29 '13 at 19:42
