From 911b499af45e879ccf4b8db234278a7136d056c9 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 28 Jan 2008 08:33:44 +0100 Subject: [PATCH] [ALSA] oxygen: make line-in exclusive only on Xonar Move the line input switching code to the Virtuoso driver because only the Xonar cards bypass the analog mixer for line input.
