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

[Paul Stewart]

Package: alsa-base
Version: 1.0.25+3
Severity: important

Dear Maintainer,

I have an iMac 12,1 and an imac 13,2.  On both machines the internal speakers work after a fresh install of Jessie but the headphones do not.  Adding the line "options snd-hda-intel model=imac27_122" to the end of /etc/modprobe.d/alsa-base.conf fixes the issue on both machines.  I don't know if it is technically the correct fix, but it does work.  I don't know what needs to be changed to get it to auto-configure correctly, but it would be excellent if it did.

Thanks,

Paul
