Following a troubleshooting post I've found out that my driver is recognized in fact but is not listed at the sound settings and I think because of this my cinnamon sound applet will not appear. Altough my device does not appear in the Sound settings I get sounds (for example youtube and skype is working) but I can not increase/decrease the volume...
I tried enabling login with root, login-logout and then login with user, restarts, following other ideas saying to fix this but still no sound devices listed... still it works (browser, skype...), alsamixer works.
Any idea on how to fix this?

Also... in cinnamon the sound applet is not displayed in unity it displays as if it were muted.
