Comment 5 for bug 1398971

I have tried the instructions Fernando said: https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS

As they are not daily DKMS packages for Unicorn I have installed the Trusty ones but it does not work yet :( The only thing it's working are my headphones, but not the speakers which work properly in Windows.

When I do "pacmd list-sinks" I get unknown availability for the speakers, any ideas?
