From 3d8bb454c4fbe18cea1adfd4183a4a9ef5f0ef04 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 28 Sep 2009 11:16:41 +0200 Subject: sound: oxygen: add stereo upmixing to center/LFE channels Add the possibility to route a mix of the two channels of stereo data to the center and LFE outputs. This is implemented only for models where the DACs support this, i.e., for the Xonar D1 and DX.
