Here's my alsainfo data: I installed Ubuntu Artful Ardvark on my macpro6,1 late 2013. no audio
http://www.alsa-project.org/db/?f=e2cb5ba4d9459547142aa6d3d2201c16ab0756a2 Please note I am plugged in to "line out" , not the headphone jack
/etc/modprobe.d/alsa-base.conf contains: options snd-hda-intel model=imac27 I tried auto, generic.. just about all possible combinations. I can only get audio out of the internal speaker.
Since headphones are detected and they are not.. I plugged in headphones in the headphone jack. No audio detected.
Does ANYONE have Ubuntu installed on thier macpro6,1 black can with audio working through the audio line out ?
