From fc1156c0b0f7ad45ec03d919866349eeca2bf18c Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 13 Feb 2012 15:04:06 +0100 Subject: ALSA: hda - Fix initialization of secondary capture source on VT1705 VT1705 codec has two ADCs where the secondary ADC has no MUX but only a fixed connection to the mic pin. This confused the driver and it tries always overriding the input-source selection by assumption of the existing MUX for the secondary ADC, resulted in resetting the input-source at each time PM (including power-saving) occurs. The fix is simply to check the existence of MUX for secondary ADCs in the initialization code.
