[alsa-devel] [PATCH] ASoC: tas571x: add input channel mixer for TAS5717/19
by Petr Kulhavy 31 May '16

31 May '16

Add channel 1 and 2 input mixer registers and the related ALSA mixer controls for TAS5717/19 chips. The mixer control coefficients on the chip are linear in the range -3.99999 to +3.99999, encoded in 3.23 number format. In this patch the mixer controls are limited to 128 values from 0.0 to 1.0 in 1/64 steps.

[alsa-devel] any reason for include/uapi/sound header files not listed in Kbuild?
by Robert P. J. Day 31 May '16

i just noticed that, in include/uapi/sound/, there are three header files: * asoc.h * tlv.h * usb_stream.h that are not referenced by the corresponding Kbuild file. is there any reason for this? or, in general, is there *any* reason for there to be header files under include/uapi/ that are not listed in their Kbuild files? thanks. rday -- ======================================================================== Robert P.

[alsa-devel] Baytrail audio port problem
by alan Paris 31 May '16

31 May '16

Hi everybody, well I send this message because I've got a problem with Baytrail audio port (rt5640). I followed the discussion about writing an alsa driver (see it : http://mailman.alsa-project.org/pipermail/alsa-devel/2015-June/094114.html) and I tried many solutions (as like that : https://groups.google.com/forum/#!topic/android-x86/GKBFxCZyxQg ). Now the system see the Baytrail card audio for speakers but as Michele Curti when I start the system I've got a minute freeze and I haven't got still sound. When I launch dmesg command, I see only those messages : Baytrail Audio Port: sst: error code = -22 bytt100_rt5640 bytt100_rt5640: BUG: , pos = -22, buffer size = 3840, period size = 480 Do you know how I can solve this problem and it is possible to operate baytrail audio device with alsa or pulseaudio ? Thanks. Regards. Alan.

[alsa-devel] ALSA timestamping for kernel SoC drivers
by Alan Young 31 May '16

31 May '16

Hello, I need to get accurate timestamping of the kind currently available for HDA into some Freescale (iMX) SoC drivers. Is there anyone already working in this area or is there anyone who would be prepared to discuss the design and implementation details? Alan.

[alsa-devel] [PATCH] ASoC: ak4642: Implement suspend callback

Add the suspend callback to accompany the existing resume operation. With the suspend/resume callbacks the regmap (regcache) state handling can follow the recommended sequence.

[alsa-devel] [RFC v2 0/3] ASoC: Add support to Qualcomm msm8916-wcd codec
by Srinivas Kandagatla 31 May '16

31 May '16

This patchset aims at adding msm8916-wcd codec support. msm8916-wcd codec is found in Qualcomm msm8916 and apq8016 processors. This codec IP is split in to two parts(Digital & Analog), Analog part is integrated in to PMIC PM8916 and the digital part is integrated into Application processor. Register access to the analog part is done via SPMI interface to PMIC, and registers on the Application processor are memory mapped. Data transfer between Analog and Digital Die is done via a internal bus called PDM. This series also add a new macro SOC_SINGLE_S8_TLV() which is used in the codec driver to control gain on a 8 bit signed gain control register. Most of this driver is ported from downstream Andriod v3.10 kernel. Jack support and Headset button detection code is not added in to this series. This codec support: - 3 Microphones: Primary Mic(Handset mic), Headset Mic and Secondary Mic. - 2 Digital Microphones. - 2 Mic Bias Circuits. - Earpiece - Headset - Loud Speaker. - Jack Detect. - Headset Button detection circuit. Tested this code on v4.6 with lpass driver Headset (Mic and speakers), Secondary Mic and Loudspeaker on DB410C. DMIC should work too. Thanks, srini Changes since RFC v1 (https://lkml.org/lkml/2016/2/16/710) - Lot of code cleanup as suggest by Mark Brown. - Fixed bindings as suggested by Mark Rutland. - merged all the patches to one as spliting the patches did not help review.
