hmmm it looks like maybe it's already fixed in the new alsa builds.
basically nothing worked and I nearly gave up but found this guide
https://help.ubuntu.com/community/So...otingProcedure

step 4 and just adding the ppa and installing the hda audio daily build works

sudo apt-add-repository ppa:ubuntu-audio-dev/alsa-daily

sudo apt-get update

sudo apt-get install oem-audio-hda-daily-dkms

reboot

then both alsa and pulse audio outputs work
