From c54728d8aa59283ece86cb745e5085ece8b4eedb Mon Sep 17 00:00:00 2001 From: Nicola Fagnani Date: Thu, 19 Jul 2007 23:28:52 +0200 Subject: [PATCH] [ALSA] hda-intel: support for iMac 24'' released on 09/2006 Basic audio support for the iMac 24'' model released on 09/2006, including headphone jack detection with automatic speaker muting. This iMac uses the Realtek ALC885 codec, not a Sigmatel one as in other models. Functionality has been tested for internal speakers, headphone and microphone.
