Hi!
I looked around the diff between 3.18 and 3.19, reverted these, and audio quality is back to reasonable level.
commit 68f438378cde79e29f71c7e043b10d76001d8892 Author: Lars-Peter Clausen <lars@metafoo.de> Date: Wed Nov 26 20:57:57 2014 +0100
ASoC: tlv320aic3x: Cleanup manual bias level transitions
Since the ASoC core now takes care of setting the bias level to SND_SOC_BIAS_OFF when removing the CODEC there is no need to do it manually anymore.

ASoC: tlv320aic3x: Add output driver pop reduction controls
Output driver has two parameters that can be configured to reduce pop noise: power-on delay and ramp-up step time. Two new kcontrols have been added to set these parameters.

ASoC: tlv320aic3x: Add TDM support
TDM support is achieved using DSP transfer mode and setting a programmable offset which specifies where data begins with respect to the frame sync.
It requires 256-clock mode if CODEC is master (not currently supported in the driver). No additional dependency if CODEC is slave.
