[alsa-devel] [PATCH 00/17] ASoC: Remove codec field from snd_soc_dapm_widget
by Lars-Peter Clausen 15 Jan '15

15 Jan '15

This series is the last part of the codec field removal from the snd_soc_dapm_widget. One small fix for an issue that slipped through earlier and the conversion of the TI and Realtek CODEC drivers and then finally the removal itself. The reason why it is removed is because it doesn't fit to well anymore in the componentized ASoC hierarchy. And the alternative of snd_soc_dapm_to_codec(w->dapm) typically generates the same amount of code, so there is really no reason to keep it. Depends on topic/w-codec and topic/rt5677. - Lars Lars-Peter Clausen (17): ASoC: mioa701_wm9713: Fix speaker event ASoC: pcm3008: Replace w->codec snd_soc_dapm_to_codec(w->dapm) ASoC: tlv320aic31xx: Replace w->codec snd_soc_dapm_to_codec(w->dapm) ASoC: tlv320aic3x: Replace w->codec snd_soc_dapm_to_codec(w->dapm) ASoC: tlv320dac33: Replace w->codec snd_soc_dapm_to_codec(w->dapm) ASoC: twl4030: Replace w->codec snd_soc_dapm_to_codec(w->dapm) ASoC: twl6040: Replace w->codec snd_soc_dapm_to_codec(w->dapm) ASoC: alc5623: Replace w->codec snd_soc_dapm_to_codec(w->dapm) ASoC: alc5632: Replace w->codec snd_soc_dapm_to_codec(w->dapm) ASoC: rt286: Replace w->codec snd_soc_dapm_to_codec(w->dapm) ASoC: rt5631: Replace w->codec snd_soc_dapm_to_codec(w->dapm) ASoC: rt5640: Replace w->codec snd_soc_dapm_to_codec(w->dapm) ASoC: rt5645: Replace w->codec snd_soc_dapm_to_codec(w->dapm) ASoC: rt5651: Replace w->codec snd_soc_dapm_to_codec(w->dapm) ASoC: rt5670: Replace w->codec snd_soc_dapm_to_codec(w->dapm) ASoC: rt5677: Replace w->codec snd_soc_dapm_to_codec(w->dapm) ASoC: Remove codec field from snd_soc_dapm_widget include/sound/soc-dapm.h | 1 - sound/soc/codecs/alc5623.c | 8 +++--- sound/soc/codecs/alc5632.c | 8 +++--- sound/soc/codecs/pcm3008.c | 4 +-- sound/soc/codecs/rt286.c | 15 ++++++----- sound/soc/codecs/rt5631.c | 28 ++++++++++++-------- sound/soc/codecs/rt5640.c | 11 ++++---- sound/soc/codecs/rt5645.c | 16 +++++++----- sound/soc/codecs/rt5651.c | 18 +++++++------ sound/soc/codecs/rt5670.c | 16 +++++++----- sound/soc/codecs/rt5677.c | 23 +++++++++-------- sound/soc/codecs/tlv320aic31xx.c | 9 ++++--- sound/soc/codecs/tlv320aic3x.c | 2 +- sound/soc/codecs/tlv320dac33.c | 9 ++++--- sound/soc/codecs/twl4030.c | 55 +++++++++++++++++++++++++--------------- sound/soc/codecs/twl6040.c | 4 +-- sound/soc/pxa/mioa701_wm9713.c | 2 +- sound/soc/soc-dapm.c | 2 -- 18 files changed, 132 insertions(+), 99 deletions(-) -- 1.8.0

[alsa-devel] [PATCH RFC] ASoC: simple-card: Enable and disable DAI clocks as needed
by Jyri Sarha 15 Jan '15

15 Jan '15

Call clk_prepare_enable() and clk_disable_unprepare() for cpu dai clock and codec dai clock in dai statup and shutdown callbacks. This to make sure the related clock are enabled when the audio device is used. Signed-off-by: Jyri Sarha <jsarha(a)ti.com> --- This patch is needed for Beaglebone-back HDMI audio. There is no direct dependency between this patch and the other (dts and DRM) changes needed for the HDMI audio so these changes can be merged independently.

[alsa-devel] ASoC Machine driver
by Ghadiya, Anil 15 Jan '15

15 Jan '15

Hi All, I am new to ALSA architecture and want to understand the flow of the driver. So I took one of the existing codec driver "adau1701" and build it for the my imx6q-sabrelite development board. I am able to build and insert it on the board. Now I want to write ASoC machine driver for the same. I am hoping that I do not need to write ASoC platform driver as my codec is not using any I2S, DMA, S/PDIF or any SOC specific driver. I have seen the machine driver for other platform. I can see that sound card is getting registered in the probe function of the machine driver, but . I am not able to understand the flow here. Could you please help me understand the flow of execution like........ when probe function of machine driver gets called? When will the probe function od codec driver gets executed? and so on.... Thanks in Advance, Anil Patel

[alsa-devel] [PATCH] ALSA: hda - Select INPUT for Realtek HD-audio codec
by Takashi Iwai 15 Jan '15

15 Jan '15

The commit commit [33f4acd3b214: ALSA: hda - Enable mic mute hotkey and LEDs for an HP machine] introduced a quirk for a HP machine involving with the input event handling. Although the relevant code is protected via IS_ENABLED(CONFIG_INPUT), this doesn't suffice when the audio driver is built in while the input is module. As an easy workaround, this patch forcibly selects CONFIG_INPUT in Kconfig. This shouldn't be a practical problem since CONFIG_INPUT is almost mandatory for all systems. Also, this allows to remove the ugly ifdefs in the code.

[alsa-devel] [PATCH - UCM 1/1] ucm: add binary configure file parse
by han.lu＠intel.com 15 Jan '15

15 Jan '15

From: "Lu, Han" <han.lu(a)intel.com> with cset command, UCM set kcontrol parameters directly: cset "name='<KCONTROL_NAME>' 1<,2,3,...>" This patch enables UCM to set kcontrol with parameters from configure file: cset-bin-file "name='<KCONTROL_NAME>' <path/to/file>" where "cset-bin-file" is a newly added keyword alongside of "cset", to indicate cset with binary data in file. The binary data is parameter only for audio DSPs, and it's just passed by UCM/ALSA as raw data. The data type of the parameter element must be byte, and the maxim number of parameter elements is 512 (the maxim value that struct snd_ctl_elem_value can hold).

[alsa-devel] Configuring slave output for ALC889
by Dheeraj CVR 15 Jan '15

15 Jan '15

Hi, I am using an Intel Desktop Board DX58SO. I am using S/PDIF for HDMI Audio and there is no sound output via HDMI. I have checked with alsamixer and the volumes for the S/PDIF are stuck at 0 and I can't increase them. By looking at the commit history, I have found this commit which enables 0x10 as a slave output for 0x6 on ALC889 for the exact same board that I am using. http://mailman.alsa-project.org/pipermail/alsa-devel/2009-April/015901.html However, it appears that with the commit "ALSA: hda/realtek - Drop ALC882 desktop model quirks", the older workaround has been removed, which caused a regression. I have checked the output of alsainfo and it seems that 0x06 is still being used instead of 0x010. Node 0x1e [Pin Complex] wcaps 0x400300: Mono Digital Control: name="SPDIF Phantom Jack", index=1, device=0 Pincap 0x00000010: OUT Pin Default 0x99430130: [Fixed] SPDIF Out at Int ATAPI Conn = ATAPI, Color = Unknown DefAssociation = 0x3, Sequence = 0x0 Misc = NO_PRESENCE Pin-ctls: 0x40: OUT Connection: 1 0x06 I was planning to edit the "patch_alc882" function to configure the "spec->gen.slave_dig_outs" and set the values to "{0x10, 0, 0}". However, I was not sure if this was the right way of doing. Please advice. I am running Arch-Linux with 3.17 kernel. -- Regards, Dheeraj CVR.
