Subject: [24/28] ALSA: hda - Fix initialization of secondary capture source on VT1705
Date: Thu, 16 Feb 2012 16:55:58 -0800 [thread overview]
Message-ID: <20120217005537.243545942@linuxfoundation.org> (raw)
In-Reply-To: <20120217005609.GA17081@kroah.com>
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
commit fc1156c0b0f7ad45ec03d919866349eeca2bf18c upstream.
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.
