[alsa-devel] [PATCH v2] ALSA: hda - Enable mic mute hotkey and LEDs for an HP machine
by David Henningsson 07 Jan '15

07 Jan '15

On this machine, the mic mute hotkey is connected to GPIO2. We therefore create an extra input device for this key. Also enable LEDs connected to GPIO3 and GPIO4. (Note: if this patch is backported to older kernels, where KEY_MIC_MUTE is not available, change the KEY_MIC_MUTE to KEY_F20, which was previously used for mic mute keys.)

[alsa-devel] [PATCH] ALSA: fm801: PCI core handles power state for us
by Andy Shevchenko 07 Jan '15

07 Jan '15

There is no need to duplicate the work that is already done in the PCI driver core. The patch removes excerpts from suspend and resume callbacks. While here amend a definition of the snd_fm801_pm. The PM core has the stubs for non-PM_SLEEP cases, thus we can always define the variable.

[alsa-devel] Intel HDA / ca0132: Multichannel + S/PDIF support
by Stefan Oltmanns 06 Jan '15

06 Jan '15

Hi, I own a Gigabyte G1.Sniper M3 Z77 mainboard with ca0132 onboard audio. Currently only stereo out and headphone out (at the back, always same signal) work by default. I was able to fix S/PDIF out by changing the headphone pin in function ca0132_config to something below 0x0d, like: spec->out_pins[1] = 0x0a; No idea why this fixes S/PDIF, but no other effects noticed. No idea if it´s going to break something on other devices. Original value is 0x10. In this function also 3 DACs are listed. The board has a total of 5 stereo outputs: -Frontpanel (HDA pin connector on mainboard) 4x 3,5mm output at backpanel: -Stereo out -Headphone out -Rear out -Center/LFE out I tried to increase the number of channels and create additional outputs and connected to the other DACs. The maximum I´m able to is to get different signals out of stereo out and front headphone (not useful, just some weird mixes) or same signal from all 3 outputs. Rear and c/lfe out always no signal. During initialization snd_hda_parse_pin_def_config is called and two outputs are found. I tried to override that and change spec->autocfg after that function is called, no success. Also no matter what I change there, a little later I get this kernel messages: kernel: [ 2.642972] input: HDA Intel PCH Line Out as /devices/pci0000:00/0000:00:1b.0/sound/card0/input8 kernel: [ 2.643142] input: HDA Intel PCH Front Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card0/input7 kernel: [ 2.644932] input: HDA Intel PCH Line as /devices/pci0000:00/0000:00:1b.0/sound/card0/input6 kernel: [ 2.645050] input: HDA Intel PCH Mic as /devices/pci0000:00/0000:00:1b.0/sound/card0/input5 I could not find the code where this messages are generated, where is that? Any ideas what I could/should try to get multichannel support working? Is there any kind of documentation on the ca0132 that could be helpful? Best regards Stefan

[alsa-devel] [PATCH 1/4] ASoC: wm8960: Let wm8960 codec driver manage its own MCLK
by Zidan Wang 06 Jan '15

06 Jan '15

When we want to use wm8960 codec, we should enable its MCLK in machine driver. It's reasonable for wm8960 codec driver to manage its own MCLK. When current bias_level is SND_SOC_BIAS_ON, it is preparing for a transition away from ON. In this case, disable the codec mclk. When current bias_level is not SND_SOC_BIAS_ON, it preparing for a transition to ON. In this case, enable the codec mclk.

[alsa-devel] [PATCH 00/21] ASoC: Use static DAI format setup
by Lars-Peter Clausen 06 Jan '15

06 Jan '15

There is still a rather large amount of board driver which manually call snd_soc_dai_set_fmt() for both the CPU and the CODEC DAI, while pretty much all of them can use static DAI setup by setting the dai_fmt field in the snd_soc_dai_link struct. Using the later method results in shorter and cleaner code and will also make it easier to eventually switch to a component type independent way to specify the clock master/slave settings (Right now the meaning of the value depends on whether a DAI belongs to a CODEC or not). This series converts all the trivial cases of snd_soc_dai_set_fmt() users to use the dai_fmt field instead. - Lars Lars-Peter Clausen (21): ASoC: sam9g20_wm8731: Use static DAI format setup ASoC: db1200: Use static DAI format setup ASoC: eureka-tlv320: Use static DAI format setup ASoC: mx27vis-aci32x4: Use static DAI format setup ASoC: wm1133-ev1: Use static DAI format setup ASoC: mxs-sgtl5000: Use static DAI format setup ASoC: ams-delta: Use static DAI format setup ASoC: raumfeld: Use static DAI format setup ASoC: zylonite: Use static DAI format setup ASoC: goni_wm8994: Use static DAI format setup ASoC: h1940_uda1380: Use static DAI format setup ASoC: jive_wm8750: Use static DAI format setup ASoC: neo1973_wm8753: Use static DAI format setup ASoC: rx1950_uda1380: Use static DAI format setup ASoC: s3c24xx_simtec: Use static DAI format setup ASoC: s3c24xx_uda134x: Use static DAI format setup ASoC: smartq_wm8987: Use static DAI format setup ASoC: smdk_wm8580: Use static DAI format setup ASoC: smdk_wm8570pcm: Use static DAI format setup ASoC: smdk_wm8994pcm: Use static DAI format setup ASoC: migor: Use static DAI format setup sound/soc/atmel/sam9g20_wm8731.c | 30 ++---------------------------- sound/soc/au1x/db1200.c | 19 +++---------------- sound/soc/fsl/eukrea-tlv320.c | 21 ++------------------- sound/soc/fsl/mx27vis-aic32x4.c | 12 ++---------- sound/soc/fsl/wm1133-ev1.c | 12 ++---------- sound/soc/mxs/mxs-sgtl5000.c | 27 ++++++--------------------- sound/soc/omap/ams-delta.c | 18 +++--------------- sound/soc/pxa/raumfeld.c | 35 ++++++++--------------------------- sound/soc/pxa/zylonite.c | 12 ++---------- sound/soc/samsung/goni_wm8994.c | 23 ++++------------------- sound/soc/samsung/h1940_uda1380.c | 15 ++------------- sound/soc/samsung/jive_wm8750.c | 16 ++-------------- sound/soc/samsung/neo1973_wm8753.c | 25 ++++--------------------- sound/soc/samsung/rx1950_uda1380.c | 15 ++------------- sound/soc/samsung/s3c24xx_simtec.c | 20 ++------------------ sound/soc/samsung/s3c24xx_uda134x.c | 12 ++---------- sound/soc/samsung/smartq_wm8987.c | 16 ++-------------- sound/soc/samsung/smdk_wm8580.c | 21 ++++++--------------- sound/soc/samsung/smdk_wm8580pcm.c | 19 +++++-------------- sound/soc/samsung/smdk_wm8994pcm.c | 16 ++-------------- sound/soc/sh/migor.c | 12 ++---------- 21 files changed, 65 insertions(+), 331 deletions(-) -- 1.8.0
