[ubuntu] alsa-hda-dkms and kernel 3.4

view story

http://ubuntuforums.org – hello fellow ubuntu users, I have a Toshiba p875 s7200 laptop and at first I had no sound (except through headphones), then I installed alsa-hda-dkms and had sound from speakers, but I was having another issue with the system freezing. So I installed latest kernel 3.4.4 and freezing problem is fixed, but I have no sound again and when I try to install alsa-hda-dkms I get error: Building only for 3.4.4-030404-generic Building for architecture i686 Building initial module for 3.4.4-030404-generic ERROR (dkms apport): kernel package linux-headers-3.4.4-030404-generic is not supported Erro (Hardware)
