From 080108c4747c7378c3601b8584237484f977d8a8 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 21 Aug 2012 14:47:18 +0200 Subject: ALSA: Follow channel position definitions to alsa-lib mixer There is already a set of channel position definitions in alsa-lib mixer.h, and it'd be more practical to keep the same order for the PCM channel map, too. The value is shifted with 1 to keep zero for UNKNOWN.
