EDIT Added ls -l /dev/snd/

EDIT Added amixer -c 0

Im trying to get my ubuntu server 12.04 lts to play a soundfile. However I always get the following error, show from a speaker-test command.

UPDATE I no longer get the following error, sound files will play (had to add my user to the sound group), however no sound can be heard.

speaker-test 1.0.25

Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels

Using 16 octaves of pink noise

What is the output of ls -l /dev/snd/? –  CL. Sep 7 '13 at 8:33
    
@CL Eddited to include ls -l /dev/snd/ –  0x0byte Sep 7 '13 at 16:20
    
If you can access the devices only as root, then your user is not an audio member. –  CL. Sep 7 '13 at 20:48
    
@Braiam I added the output of amixer -c 0, I dont have pulse audio installed since this is just a server without a gui. –  0x0byte Sep 15 '13 at 18:09
    
@0x0byte you may want to ask another question so I can move my answer there. –  Braiam Sep 15 '13 at 18:23

Both Master Mono and Surround are muted. If you toggle them it should work fine:

amixer -c 0 sset 'Master Mono' toggle
amixer -c 0 sset 'Master Surround' toggle

If you want to change the off to on just repeat the same commands using the name of the device.

For changing the volume you should use:

amixer -c 0 sset 'Master Mono' 100%
amixer -c 0 sset 'Master Surround' 100%

Thats probably my problem with the integrated card, I got it working with pci card though and added my solution to the post. Although I had to do to unmute it as well. –  0x0byte Sep 15 '13 at 18:40
    
@0x0byte instead editing your question to add the solution, write a answer using the camp below... –  Braiam Sep 15 '13 at 18:42

Solved by adding my user to the sound group.

sudo useradd -G sound {username}

Then forced my integrated soundcard to have an index of 1 so the pci card defaults to 0.

Find the card you don't want to be the deafult. Mine is snd_intel8x0. The current default has the index of 0.

cat /proc/asound/modules

0 snd_cmipci
1 snd_intel8x0

Modify the conf file so the card you don't want as default is set to index 1

sudo nano /etc/modprobe.d/alsa-base.conf

Find the line:

# Prevent abnormal drivers from grabbing index 0

and add the following below it, using the name of your soundcard in place of my snd_intel8x0

options snd_intel8x0 index=1

Finally reboot and use the alsamixer to ensure the card isnt muted.
