[Pkg-alsa-devel] Bug#743936: Bug#743936: alsa-base: Default configuration does not work on iMacs

[Paul Stewart]

I ended up reinstalling Jessie on this machine (I am trying to figure out
the best triple boot config).  I double checked that mixer settings were
correct and they were, but the headphone out did not work.  "# echo
"options snd-hda-intel model=imac27_122" >> /etc/modprobe.d/imac_local.conf"
+ a reboot fixed the issue.
