Cannot play sound, ALSA lib errors
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

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_intel8x0Modify the conf file so the card you don't want as default is set to index 1
sudo nano /etc/modprobe.d/alsa-base.confFind the line:
# Prevent abnormal drivers from grabbing index 0and add the following below it, using the name of your soundcard in place of my snd_intel8x0
options snd_intel8x0 index=1Finally reboot and use the alsamixer to ensure the card isnt muted.
alsamixerBoth 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' toggleIf 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%
