From 1af7c5f0d48dca385f29610cc62435afc13237cf Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 24 Jun 2011 10:43:03 +0200 Subject: [PATCH] ALSA: hda - Add a workaround for invalid line-out setups Some BIOS set up the pin config wrongly as line-out although it's supposed to be a speaker out. In most cases, though, we can judge the validity by checking the connection type -- when it's FIXED, mostly it's an invalid line-out but a speaker.
