Hi!

My problem is that all my apps freeze when instead of playing any sound unless I run them as root

aplay -l

**** List of PLAYBACK Hardware Devices ****
[freezes here]

sudo aplay -l

[sudo] password for peter:

Could you tell me your Ubuntu version, and your kernel version (you can get it by typing uname -r in a Terminal window)?

Try this in a Terminal window (copy and paste):

sudo usermod -aG `cat /etc/group | grep -e '^pulse:' -e '^audio:' -e '^pulse-access:' -e '^pulse-rt:' -e '^video:' | awk -F: '{print $1}' | tr '\n' ',' | sed 's:,$::g'` `whoami`

Hello, I have the same problem too. I've recently updated from Natty to Oneiric and I now my sound card is not detected. My kernel version is: 3.0.0-12-generic.

Also, I've run the alsa info script that generated a log file for me, here it is: http://www.alsa-project.org/db/?f=de...1572f97daab012.

Any help would be appreciated.
Thanks in advance

Hello lkjoel, thanks for your help.
The command returns:

aplay: device_list:240: no se encontraron tarjetas de sonido...

(in English: no sound cards detected)

What's next?
Thanks

I have followed the instructions which lead me to another post (http://ubuntuforums.org/showthread.php?t=1681577). Following the steps in that post lead me to an error while compiling (step 6):

seq_clientmgr.c:27:28: error fatal: linux/smp_lock.h: File or directory not found
compilation ended.
make[3]: *** [fastdep] Error 1
make[3]: se sale del directorio «/opt/Alsa-1.0.24/alsa-driver-1.0.24/acore/seq»
make[2]: *** [_sfdep_seq] Error 2
make[2]: se sale del directorio «/opt/Alsa-1.0.24/alsa-driver-1.0.24/acore»
make[1]: *** [dep] Error 1
make[1]: se sale del directorio «/opt/Alsa-1.0.24/alsa-driver-1.0.24»
make: *** [include/sndversions.h] Error 2

(note: I've translated the important part to English, so it may not be the exact phrasing)

Reading the last posts of the thread (#120+), I found out that the smp_lock.h file was removed from Oneiric. Another user states that installing the alsa firmware should fix it, but in my case it doesnt.

What should I do?
Thanks again

Could you give me the full output of this Terminal command?
