[ubuntu] Soundcard is not fully recognized (stuck on the troubleshooting procedure)

view story

http://ubuntuforums.org – Hi, I'm trying to understand what exactly is the problem, but not so sure. I’m using Ubuntu 11.10 (Kernel 3.0.0-26), and stuck on the troubleshooting procedure. When using the command: aplay -l It gives the following output: aplay: device_list:240: no soundcards found... So I go to Procedure Ac (Make the system/ALSA recognize the sound card), and everything seem to be fine there, so I'm a little bit stuck. Sound cards recognized by the system: 00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 02) Sound cards recognized by ALSA: 00: (Hardware)
