From 8fa7ab48acb636d24669dab291807b487dfb2804 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 26 Oct 2011 16:06:27 +0200 Subject: ALSA: hda - Fix surround/CLFE headphone and speaker pins order When 5.1 or more headphone or speaker pins are provided, the parser still takes as is without fixing the order of channel mapping, which leads in the unexpected strange channel order by surround outputs. This patch fixes the issue by applying the same fix-up not only to line_out_pins[] but also hp_pins[] and speaker_pins[].
