No sound driver loaded? What's in /proc/asound/cards?

cola · 01-29-2010, 07:53 AM

cat /proc/asound/cards

Code:

 0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0xfdff8000 irq 16

Please check that /dev/snd/controlC0 and /dev/snd/pcmC0D0p exist, that you have permissions to access them, and that they have the same minor device numbers as listed in /proc/asound/devices.

... and is your user member of the audio group, and what are the contents of /proc/asound/devices?

Code:

I did:

Code:

chown <user> /dev/snd/controlC0 pcmC0D0p

ls -l /dev/snd

Code:

crw-rw---- 1 user audio 116,  0 2010-01-30 00:37 controlC0
crw-rw---- 1 root  audio 116,  4 2010-01-30 00:37 hwC0D0

crw-rw---- 1 user audio 116, 16 2010-01-29 20:24 pcmC0D0p
crw-rw---- 1 root  audio 116,  1 2010-01-29 18:38 seq
crw-rw---- 1 root  audio 116, 33 2010-01-30 00:37 timer

Still ,mpg321 01.mp3

Code:

ALSA lib pcm_direct.c:1113:(snd1_pcm_direct_initialize_poll_fd) unable to open timer 'hw:CLASS=3,SCLASS=0,CARD=0,DEV=0,SUBDEV=0'
ALSA lib pcm_dmix.c:1085:(snd_pcm_dmix_open) unable to initialize poll_fd
No default libao driver available.

Add yourself to the audio group.

Now it tried to open the timer device.

You are not supposed to change the permissions of the device nodes for each user; the user should get the appropriate group membership.
"usermod -a -G ..." should have helped.

Did reboot and it's done.
