Subject: Re: 3.19 on Nokia n900: audio quality awful
Date: Fri, 30 Jan 2015 11:26:39 +0100 [thread overview]

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.

commit 68d6626925c3529790a2055d41578415fa98495e
Author: Misael Lopez Cruz <misael.lopez@ti.com>

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.

commit 368494093354ac613a80c2e1d77602aa12473cf0
Author: Peter Ujfalusi <peter.ujfalusi@ti.com>
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.
