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@xxxxxxxxxx> 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. Signed-off-by: Lars-Peter Clausen <lars@xxxxxxxxxx> Signed-off-by: Mark Brown <broonie@xxxxxxxxxx> commit 68d6626925c3529790a2055d41578415fa98495e Author: Misael Lopez Cruz <misael.lopez@xxxxxx> Date: Tue Nov 11 10:59:01 2014 +0200 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.

It requires 256-clock mode if CODEC is master (not currently supported in the driver). No additional dependency if CODEC is slave.
