From ce764ab22e40a046065c9417ee5f04ad2a816ac1 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 27 Apr 2011 16:35:23 +0200 Subject: [PATCH] ALSA: hda - Add channel-mode support to Realtek auto-parser This patch adds the support of "Channel Mode" enum control to Realtek auto-parser. When line-in or mic-in jacks are capable to output and free DACs are available, the driver allows to switch to multi-channel mode via "Channel Mode" enum switch, as already implemented in some preset cases. Not implemented in all Realtek codecs. Currently, ALC880, 882, 861, 662 and the compatible codecs are supported.
