From e8b99a1dcb49b0d362b19a4831a00d85c76bd4b3 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 27 Feb 2014 16:24:53 +0100 Subject: [PATCH] ALSA: hda/sigmatel - Allow auto-switching for dock line-in of HP laptops Many HP laptops with STAC codecs have a docking station port and BIOS sets the pins for the input on the dock as a line in. Because the generic parser doesn't handle a line in pin as auto-switchable, this resulted in the manual capture source selection on these laptops. However, from the usability POV, the automatic switching is easier. This patch adds the line_in_auto_switch hint in the fixup function for these laptops. Even if no dock port is present, this should be harmless as the generic parser allows the auto-switching only in a limited situation (all three pins are located in different positions).
