From 5832fcf8b55cfdbd7d8511f747d15fd20ed4703d Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 12 Feb 2008 18:30:12 +0100 Subject: [ALSA] hda-codec - More fix-up for auto-configuration In some cases, the BIOS sets up only the HP pins with different assoc and sequence numbers, e.g. on FSC Esprimo with ALC262. This patch adds a fix-up for such a case. When multiple HPs are defined and no line-outs is found, the configurator tries to re-assign some pins from HP list to line-out, judging from the sequence number.
