From cd4035e814b04c009ece9939396d06370c53ed44 Mon Sep 17 00:00:00 2001 From: David Henningsson Date: Thu, 10 Oct 2013 09:01:25 +0200 Subject: ALSA: hda - Enable surround speakers (when line out is also present) In the case where we have both line out and more than stereo speakers, the speaker DACs will end up in extra_out_nid. In fact, AFAIU, speakers are the only ones that can end up in extra_out_nid, and if we have several of those, they should be surround outputs rather than copy front.
