Just to comment: the system does not recognize the soundcard. You might want to reinstall the firmware.
To get manually the type you can command line: 'sudo lshw'
You will find appropriate information at "multimedia" tag.
Or optionally: 'aplay -l'

You will find more information about installing soundcard firmware below.

Hope this will get the device work.
