My installation of elementary OS does not detect my sound card. I suspect this is related to an incompatibility between my kernel and ALSA. Below I have attached the output of the commands in Step 3 of

https://help.ubuntu.com/community/SoundTroubleshootingProcedure#Step_4

I hope someone can give me an hint on what to do ... I really appreciate your help!

Best Mattia

Step 3

bash alsa-info.sh --stdout
alsactl: save_state:1595: No soundcards found...
cat: /tmp/alsa-info.CCfyZ3Xijy/alsactl.tmp: No such file or directory
