From 7bb8442c111d5e1fba20eb101eb854edd5392627 Mon Sep 17 00:00:00 2001 From: Tanu Kaskinen Date: Tue, 1 May 2012 20:09:12 +0300 Subject: [PATCH] alsa: Add support for sound cards with 4-channel input. Changes in v2: - Call the mapping a generic 4-channel input mapping instead of a 4-channel mic array mapping. The mapping will be used also by sound cards that have two stereo input jacks, so in those cases talking about mic arrays is wrong. - Added a comment about using the "hw" device name.
