This seems to be an upstream kernel bug. I am having problems myself with this. Not sure if the latest ppa release will fix this. Upstream fix feb13, ubuntu ppa date feb16. Posting this up while the data is on my screen, before I do the reboots and such ...
From: http://www.kernel.org/pub/linux/kernel/v3.0/ChangeLog-3.2.7 commit 852c3a36c216e351d07ca96e9af30b81fff30ccc Author: Takashi Iwai <ti...@suse.de> Date: Mon Feb 13 15:04:06 2012 +0100 ALSA: hda - Fix initialization of secondary capture source on VT1705 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.
