sound problems Lenovo ideapad s410p
I bought a new Lenovo ideapad S410p with windows8. I erased windows8 and made a new partition table where I installed Ubuntu 12.04lts. Everything is working except the sound.
I've installed GNOME ALSA MIXER where I can see Intel Haswel HDMI (IEC958) and Realtek ID 233. I have typed
sudo nano /etc/modprobe.d/alsa-base and change the document (which for me is actually empty!) by typing
options snd-hda-intel model=lenovo but after rebooting it does still not work.
I tried also options snd-hda-intel model=ideapad, and options snd-hda-intel model=generic.
Then I have used the following script to update ALSA with no luck http://www.stchman.com/alsa_update.html.
I'd really appreciate your help!
