17 Nov '17

From: Markus Elfring <elfring(a)users.sourceforge.net> Date: Fri, 17 Nov 2017 10:32:23 +0100 A few update suggestions were taken into account from static source code analysis. Markus Elfring (4): Adjust 13 function calls together with a variable assignment Delete an unnecessary variable initialisation in snd_riptide_proc_read() Reduce the scope for two variables in snd_riptide_proc_read() Use common error handling code in snd_riptide_create() sound/pci/riptide/riptide.c | 78 ++++++++++++++++++++++++++------------------- 1 file changed, 46 insertions(+), 32 deletions(-) -- 2.15.0

[alsa-devel] [PATCH] ASoC: Intel: Add defaults for SND_SST_ options and machine drivers
by Pierre-Louis Bossart 17 Nov '17

17 Nov '17

Add 'default m' when sensible, move common dependencies in if/endif block and clarify which options default to n - distro configurations should not enable legacy Baytrail stuff and NOCODEC (test only) Basic tests run with defconfig, oldconfig, olddefconfig, there should be no functionality change.

[alsa-devel] [PATCH 1/3] ASoC: nau8540: reset state machine for channel phase sync
by John Hsu 16 Nov '17

16 Nov '17

The four channel ADCs in NAU85L40 have difference control registers, it is hard to synchronous these four channels without correct sequence. The phase difference will not be a constant and not to conjecture easily. It may be 2.55 degree, or more ,or less. Intended to prevent phase difference of channels, the solution as follows: (1)Channel_Sync need to be enabled. (2)Do soft reset without affecting register when recording done.

It is possible to get the fake key press interruption when the codec do jack detection. We think it's proper to move the key interruption configuration after jack detection done.
