[alsa-devel] [PATCH] ALSA: hda - Fix inconsistent Mic mute LED
by Takashi Iwai 06 Feb '14

06 Feb '14

The current code for controlling mic mute LED in patch_sigmatel.c blindly assumes that there is a single capture switch. But, there can be multiple multiple ones, and each of them flips the state, ended up in an inconsistent state. For fixing this problem, this patch adds kcontrol to be passed to the hook function so that the callee can check which switch is being accessed. In stac_capture_led_hook(), the state is checked as a bitmask, and turns on the LED when all capture switches are off.

>From 1ac8268330df7564edf252a542a27f3cf4f4472f Mon Sep 17 00:00:00 2001 From: Valentin Corfu <valentinx.corfu(a)intel.com> Date: Fri, 31 Jan 2014 08:06:23 -0500 Subject: [PATCH 1/2] Allow to specify a client name as parameters The current jack client name contains the process id of the application providing the audio samples. This leads to unpredictable jack client names which makes handling of the connections by a controlling application very hard. This modification now, allows to specify a client name as parameters in the configuration file. The implementation is backward compatible and simply adds a new configuration option to the plugin.

[alsa-devel] [PATCH v3 0/5] add a TDA998x CODEC
by Jean-Francois Moine 05 Feb '14

05 Feb '14

The TDA998x HDMI transmitter accepts audio input from either I2S or S/PDIF. Theses inputs have different intrinsic constraints and these constraints may be modified by the audio parameters of the connected video device. The choice of I2S or S/PDIF may be the done by the user or by automatic processing (DPCM?) at each audio starting time. This asks for a dynamic audio input switch in the HDMI driver. This patch series implements the TDA998x specific CODEC. A simple function call mechanism is used for exchanges between the CODEC and the HDMI driver. Note: the changes in the TDA998x I2C driver are based on my previous patch series: http://lists.freedesktop.org/archives/dri-devel/2014-January/052837.html - v3 - move the DT description of the CODEC as a subnode of the TDA998x I2C (Mark Brown remark - is this the right way?) - change CODEC loading mechanism - simplify tda998x i2c reference search - CODEC DT documentation in drm/i2c/tda998x.txt - v2 - add ACLK setting and code optimization in patch 1 - from Mark Brown's remarks in patch 2: - don't compile the codec when CONFIG_ALL_CODECS - simplify the code about start/stop audio - fix coding style errors - add audio-port-names associated to audio-ports - add audio-port-names in patch 4 - add patch 5 'adjust the audio CTS_N pre-divider from audio format' for the Beaglebone-Black board (Jyri Sarha) Jean-Francois Moine (5): drm/i2c: tda998x: add a function for dynamic audio input switch ASoC: tda998x: add a codec driver for the TDA998x ASoC: tda998x: add DT documentation of the tda998x CODEC ASoC: tda998x: adjust the audio hw parameters from EDID ASoC: tda998x: adjust the audio CTS_N pre-divider from audio format .../devicetree/bindings/drm/i2c/tda998x.txt | 17 ++ drivers/gpu/drm/i2c/tda998x_drv.c | 86 +++++- include/drm/i2c/tda998x.h | 11 +- sound/soc/codecs/Kconfig | 6 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/tda998x.c | 303 +++++++++++++++++++++ 6 files changed, 419 insertions(+), 6 deletions(-) create mode 100644 sound/soc/codecs/tda998x.c -- 1.9.rc1

[alsa-devel] [PATCH] ASoC: cs42l73: Don't mix SNDRV_PCM_RATE_KNOT with specific rates
by Lars-Peter Clausen 05 Feb '14

05 Feb '14

SNDRV_PCM_RATE_KNOT means that the device can support rates that can not be expressed using the rate bits. The driver will provide a list of those rates specified through constraints. Any rate bits that are set in the rates mask will be ignored. So setting other rate bits besides SNDRV_PCM_RATE_KNOT wont have any effect, but might be confusing to the casual reader, so remove them.

[alsa-devel] [PATCH] MIDI driver for Behringer BCD2000 USB device

This patch adds initial support for the Behringer BCD2000 USB DJ controller. At the moment, only the MIDI part of the device is working, i.e. knobs, buttons and LEDs. I also plan to add support for the audio part, but I assume that this will require more effort than the rather simple MIDI interface.

[alsa-devel] [PATCH] ASoC: cs4271: Remove outdated comment

Commit 1b1861ead ("ASoC: cs4271: convert to direct regmap API usage") removed the bus_type field from the cs4271_private struct, but left the comment that described the field in there.

[alsa-devel] [PATCH 1/2] ALSA: hda - hdmi: introduce patch_nvhdmi()
by Stephen Warren 05 Feb '14

05 Feb '14

From: Anssi Hannula <anssi.hannula(a)iki.fi> (This is a backport of *part* of upstream 611885bc963a "ALSA: hda - hdmi: Disallow unsupported 2ch remapping on NVIDIA codecs" to stable 3.10 through 3.12. Later stable already contain all of the original patch.) Mainline commit 611885bc963a "ALSA: hda - hdmi: Disallow unsupported 2ch remapping on NVIDIA codecs" introduces function patch_nvhdmi(). That function is edited by 75fae117a5db "ALSA: hda/hdmi - allow PIN_OUT to be dynamically enabled". In order to backport the PIN_OUT patch, I am first back-porting just the addition of function patch_nvhdmi(), so that the conflicts applying the PIN_OUT patch are simplified. Ideally, one might backport all of 611885bc963a. However, that commit doesn't apply to stable kernels, since it relies on a chain of other patches which implement new features.
