From e97f79994ac715e4c8724b201bd3328463ec9314 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Tue, 1 Apr 2008 10:02:18 +0200 Subject: [ALSA] oxygen: fix line-in recording selection (now for real) On C-Media cards, the GPIO pin 0 of the CM9780 must be handled exactly like on Xonar cards, so move the Xonar code to the common mixer code.
