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 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 Signed-off-by: Mark Brown commit 68d6626925c3529790a2055d41578415fa98495e Author: Misael Lopez Cruz 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. Signed-off-by: Misael Lopez Cruz Signed-off-by: Peter Ujfalusi Signed-off-by: Mark Brown commit 368494093354ac613a80c2e1d77602aa12473cf0 Author: Peter Ujfalusi Date: Mon Nov 10 12:27:33 2014 +0200 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.
