From 75919d7c057be888c7cd7b192fad02182260b04a Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 28 Sep 2009 11:15:49 +0200 Subject: [PATCH] sound: oxygen: better defaults for upmixing control On card models with two-channel outputs, the base driver can automatically disable the upmixing control so that the model drivers do not need to do this.
