From eaeae5d9b783a62e435645122bed90561924a2d6 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Wed, 30 Sep 2009 09:27:24 +0300 Subject: [PATCH 01/12] ASoC: Fix SND_SOC_DAPM_LINE handling Since the SND_SOC_DAPM_LINE can be input or output, additional check is needed in order to determine if the widget is connected as input or output. When checking for connected outputs, if the widget is line, than check if the sources list is not empty (line is connected as output) For input endpoint check, when the widget is line, also check if the sinks list is not empty (line is connected as input).

This ends up with the doubled initialization of the same mixer widget, and it mutes the DAC route because hp_pins has no DAC assigned. To fix this problem, just check spec->autocfg.hp_outs and speaker_outs so that they are really detected pins.
