From b201131c43c155c62e799d9410708d10b2c9a6ad Mon Sep 17 00:00:00 2001 From: Tobin Davis Date: Mon, 17 Sep 2007 12:45:11 +0200 Subject: [PATCH] [ALSA] hda-codec: Add 4 channel support for Realtek ALC883 I had a request for a 4 channel mode. This should implement front and surround outputs, leaving the 3rd plug for mic input.
